We switch turbo and it paid off, we are very proud to offer the full line of bullseye power turbo wich we used on my passat. these turbos will support 40psi no problem and comes with a full year hassle free waranty.

we used a S258 with SS turbine housing .55a/r t3 and 4"inlet ported shroud cover.

they flow enough to make 600whp but they spool alot quicker than similar sized ball bearing turbo. they have extended tip technologie wich increases flow and map efficiency. but these turbos are not Ball bearing and are only oil cool. more info www.bullseyepower.com

this turbo gets full boost at 4100rpm but flows like a gt35r on 1.8T

made 360WHP 300ft/lbs@23psi pump
418whp 384ft/lbs on race fuel

this is a 100% stock small port head/intake tb and only uses IE rods.


huge thanks to eurodyne.ca for the great tune

What kind of warranty does the manufacture cover? Is there a dramatic drop reliability since it is not water cooled?

hassle free for 1 year. these turbos last no problem, they are not alot of people making waranty claim. www.bullseyepower.com

Do you guys offer a water-cooled ball bearing line-up?
I heard banks systems aren't water cooled or ball bearing, and will go out after 30,000 miles.

I'd deffinatly be a good switch from ATP. I don't like their products, but sadly already bought one of their turbos.

Can you post the dyno plots from the Passat? Some pictures of the install would also be great. Sounds more like 3071 power than 35r.

I have a buddy swapping out to these guys turbos. He is expecting good results. Saw the turbo this past weekend and it looked good. He is making around 900whp in a moostang.

Apparently this thing gets more boost/power/torque at lower RPMs then a GT30R

im not seeing this turbo make 600fwhp unless it's at 40psi on C16.. mike hoods make more than 600fwhp(i know he's AWD, but just for comparison) on only 32psi with his 35r on a 2.0l.. i wan't to see this dyno plot and what psi/octane you acheived this 418fwhp..

08-27-2007, 05:22 PM
this is 100% stock small port head/intake/tb motor with small precisison 300hp intercooler, there is more in the set up right now but i told him to stay conservative. boost settles at 28psi on C16. Dyno is just a number im hitting the track this sunday with my passat wagon full leather heavy ass car to see.

compresssor wheels flows for 62lbs@70%efficiency and will support 40psi no problem.

would love to see the dyno and motor set up on the 2.0 20v 600whp@32psi numbers.

look at both GT35R VS S258 that don' t lie but dynos can be adjusted if wanted too.

again this is my set up im picking up the car tommorow and will post the dyno sheet after.

I tuned my buddy 1.8Tmk3 gt30R .63 t3 ball bearing and he gets full boost at 4800rpm i get full boost at 4100rpm wich is what i really enjoy about this turbo and it flows 62lbs. wich to me is best of both worlds. IMO

You cannot compare apples to oranges, you had a GT28 variant in there and swap it out to a turbo with a 58mm compressor wheel lol, do even a GT3071R turbo at least for the comparison, otherwise it's a joke of a comparison that you have going.



we used a S258 with SS turbine housing .55a/r t3 and 4"inlet ported shroud cover.

they flow enough to make 600whp but they spool alot quicker than similar sized ball bearing turbo. they have extended tip technologie wich increases flow and map efficiency. but these turbos are not Ball bearing and are only oil cool. more info www.bullseyepower.com

all that i can see there is that the turbo uses bigger wheels than your GT28 variant, and you need 4:1 pressure ratio to flow 60lbs/min. Have you ever seen a GT35R put down 650awhp? I have. also, garrett does have a GT35RST that's smaller then the full 35R, spools much faster and flows about the same, but i'd like to see your dynograph first.

Not hating but you're not saying much unless you post at least a dynochart and small port heads flow pretty good and have a better air/fuel mixture than the large port heads due to their port shapes being concave up and forcing the air to have a swirl effect.
hope this helps

I never compared my gt28s to this turbo??

i made a turbo kit using the gt28s wich i maxed out at 360whp.

then i wanted to try something different and it paid off since i wanted to make 400+whp.

like i said this turbo flows 62lbs that you like it or not. and at 3.1 pressure ratio you hit 60lbs .

I still don't get you guys the GT35R flows 60lbs same has the S258 but how me a GT35R that gets full boost at mid 4000rpm.

local guy here could not get full boost to even make the car driveable on stock 1.8t

yes mine is .55 VS .63

and gt35 .63 surges

i have yet to post a high hp number without you Paul being all over me for reasons i don't get?

what if i had made those numbers with a garrett everybody would be happy?

I never said this is the best thing, i said it flows for 62lbs and i get full boost mid
4000rpm. if you don't like it i don't care, im still hauling my 2 kids in my 400hp wagon everyday....

I also only run 110 octane to get that 600whp. Funny thing is that dave at eurocode was able to make 400whp/wtq on a FWD GTI with a 2 liter and just a GT2871R running 25psi on 105 octane. Now just think if I was just FWD, my car would be making about 650whp running the same boost level.


What I really find funny is the fact that someone is trying to post a "I sell this" thread but isn't a AZ advertiser.[confused]


Also what the hell is a GT28"S"? I have heard of the R, RS, 71R but never the S.




then i wanted to try something different and it paid off since i wanted to make 400+whp.




yes different but something that hasn't been tried before. I made 434whp on my quattro with the airwerks turbo pushing 24psi on a mix fuel that was around 95 octane.

Marc, it is great to see those rods working out for you. We put down 423 whp on one of our own daily drivers with a set on a 3071r. That was about all the turbo would do at this altitude without any headwork / cams / intake manifold etc.

sorry again if it sounded like a sales pitch im a sponsor on other forums and i copy/paste here, should of re-done it to not offend anyone here.

I have seen way to many high# dyno only to not even pull good trap speed for lighter cars. that is why im not a fan of dyno# they always seem to dissapoint, unless i rig it to get a huge number wich does not help anything.

nobody ran this turbo, i did got 418whp with no surging and alot more left. im sure one of you guys would install it and make more then me...

kinetic vr6 turbo kit only put down 222whp on 3 different installs at our shop. everywhere else i read about everyone is putting alot more down.

the flow map is what it is, the dyno# is always gonna be left for debate.

thanks Pete yeah those rods are working awesome, thanks again.

Just saying to post up the dyno that's all, i never had problems with a 35r surging on my car and i run T04S housings with anti surge. Not all over your numbers, just saying to post up a dyno really.

I dont have any kids but i do "haul" my boxer around my gti's and Audi everyday.
As far as rods go, i've made over 500whp with stock ABA's, dont mean that they'll last long though.

This is very interesting...if I still had my car and everything jived, I'd be really tempted to try one of these out. I made full boost at about 4100 rpm so with one of these, full boost at 4k+ and over 400 whp sounds more that tolerable to me. I haven't looked at the price point compared to garrett but whats the cost on one of these? Like I said, everything would have to jive...oh and I would need a car lol.

Either way it's great to see more variety from the aftermarket.

Well everyone here knows what a well tuned GT35r on a 2 liter will do since my car is a pretty big proof of it, plus a few other cars that make big power with the GT35r. My car put down 556awhp on a low reading dyno, really makes about 600awhp maxed out on 1000cc injectors. It has put down a 134 mph trap speed at a weight of around 2960 lbs with driver at Fontana(1400ft) in 80 deg temps and also put down 128+ mph trap at LACR(2710ft) also in 80 deg temps. With that people know exactly what they can get out a turbo that has been around for some time when put into a Audi A4. Hell I have even seen that same turbo put down 580whp on a friends Evo8 and 700+whp on a Civic at Full-race.

Rememer that is 400+whp on a fwd car, which would be closer to 370-380whp on a quattro.

Mike, a 35R can do 650AWHP depending on the head, this particular case was done on a 1st gen dsm.
Not talking about vtec civics because they have a different powerband.
The dyno isn't clear, i'd like to take a better look but it's just not clear enough for me.

Yeah. Right now I am only getting about 600whp since I am only running 104-110 octane at 11.5:1 AFR and maxed out 1000cc injectors. I am sure I could get a bit more out of it if I was running C16 and 12.5:1 which is what the C16 loves to be ran at. I would also love to see what the GT35r would make on alcohol.[:D]

really the one that they like to match up to the gt35r is there s362 line up not the s258. altough the map states a 60lbs for the s258 like the gt35.

i drove the car today and i so don't care what all the opinions are, this thing spools crazy fast shifting at 7500rpm no drop in between shifts like some xperts say etc etc. i love driving this car with this set up, period.

I would still love to see a dyno please of a gt35r .63 on stock 1.8t if possible. and GT30r .63. thanks on mustang not dynojet or dynopack

power curve is flater also instead of a peak. this is at same boost too 28psi

Is the first peak in your dyno the boost graph?

Asking because you said you run 28psi which I am going to guess is what boost level you hold but then how much boost is on that huge boost spike? Also it looks to peak at 4500 rpm while you say you hit full boost at 4100 rpm.


I notice all the points you use are where your car makes peak tq which is at 5k while his doesn't peak till 6k, this basicly means your acceleration is dropping off while his is still pulling hard. Yes your car would be quicker pulling from low rpm's which might be good for street driving or a tight road course/autox, but if both cars are drag racing his car would just pull pretty hard away from your car. I also think if you were to remove the boost spike you have your tq wouldn't be as high and this is going to happen when you dont put a huge load on the car like you got on the dyno.

the spike is 30psi but that is not where im making peak power.but woudl affect some. that happens when boost comes in quick.

on pump gas i get full 23psi at 4000rpm, on race you see it`s before 4500rpm and computer said 4300rpm sorry i was off by 200rpm. when i posted it i went with what chris told me.

my car has over 315ft/lbs at redline wich is close or same has the other turbo so it pulls harder earlier and stays that way till 7000rpm.

can you post a better picture, the #'s at the bottom are way to blurry to see.


Yes you are right you do have tq much sooner, but after that point it is falling while his is still increasing and at 7k he making about 330ft/lbs and 450whp vs your 315ft/lbs and 417whp.

BTW it looks like you have a few boost creep spots on your pull, every time the boost creeps up your hp increases just after it. On the other dyno it looks like his boost is smooth thru the whole run which means he must be using a good boost controller.

he is making peak 375 and falling to 330ft/lbs so he is dropping off has well, wich is to be expected from small port head and cast log manifold, does he even have the motor has me and manifold??

im running the small kinetic intercooler wich is not a Garrett core like precision so im sure a better more efficient intercooler will of course increase hp.

not sure we are comparing same thing, but mine comes in sooner, makes alot more torque where needed at the loss of 40whp wich is not even on same dyno with same components... way too many variables to determine peak HP numbers, but can`t denied the power curve and when boost comes in...

and that chart it not the same has the mustang, so not sure if we are accurate to compare. i don`t have a scanner maybe i will borrow one.

once i put my fully ported AEB with supertech valvetrain, you will see much higher numbers has one should expect.

gonna have to do a in car video on pump gas to show i guess...

We can compare mustang to mustang right here.

On the dyno it doesn't matter what core you have since you are just doing 1 gear pulls, the fmic isn't going to come into play till you do full multi gear pulls or back to back pulls with no cool down.

Your turbo comes on sooner because the exhaust side is smaller. If you didn't have that boost creep your hp would have dropped just like his which means your peak hp would have been much lower.

with the name on the sheet im not 100% convinced it`s a stock small port head.
anyway this subject is long overdue.

That is my dyno sheet and yes you are right it has a AEB head with upgraded valvetrain and custom intake manifold. I haven't had a small port head on the car since 2002 when I had the PES T28 kit.

The small port head should help the middle of the powerband and hurt the top. Those smaller ports will increase velocity and help power up until they become a flow restriction at higher rpms. Same thing happens on the exhaust side. Smaller runners like a log mani will outspool a tube manifold that flows better up high. Which reminds me, if you are using the stock placement ATP manifold then you really need to swap in the 034 cast mani. Everything is in the same spot but flow is way up.

Pretty sure he isn't using the stock placement ATP manifold but the one that is basicly a copy of the ATP manifold with the turbo mounted right off the side. There are pics of his manifold/turbo on the first page and on another thread he had made.

it's not the atp but the replica im using.

this is pretty basic, this winter i will have the full AEB head/supertech valvetrain tkrace.com ported head etc then the numbers will be different.

just notice my SS WG flange had warped under welding and i did not check it, it was leaking pretty bad when i picked up the car, it was leaking at the manifold so boost pressure was affected

Duh. You're right. Still, a better manifold would be a large improvement.

It'd be nice to see a graph of someone with a "high flow" stainless steel manifold vs the same setup with a log cast. I'm using an ATP type manifold but with thicker walls and much better path to the studs. The other local guy using the same manifold on a B5 has put down well over 550whp. Peace of mind that this thing will never crack is pretty much priceless in my book. That's why i tell people that we can make Welded manifolds but if they want my opinion then they're better off with a good cast, and im not talking about that cheap gray metal BS found on ebay for $150.[:D]

I'd like to see a comparison between the stock placement ATP and 034's version. Flow bench numbers don't always correlate with dyno numbers or acceleration.

They seem to think that it does!

Why do you want to compare a stock flange mani to a t3 flange manifold?

I think he is talking about the 2 stock type of manifolds, the one from ATP and the one 034 sells which is the one Issam posted up about.

Exactly. It would illustrate the difference from a power production standpoint Then maybe 034 could cast a replacement for the manifold he is currently using with higher flow, better fastener access, and better turbo position. Guess I want a lot huh.

Equal lenght cast that puts the turbo right on top, that's the old AMS manifold for the 16v's, i love those[:D]

Or similar to the APR manifold. I'd also love to see a twin scroll manifold but there isn't much room in there.

im down for seeing that.

here's a transverse twin scroll mani that i know you've probably already seen. but man, the thing is a freaking crazy straw! im sure you could fit one in our car. but the intake/TP+DP setup might be a little tricky

Wow. That is a pretty lump of pipe. Not that I want to own or run it though. Or pay for all that tricky welding. That must take awhile to get to the point that it'll pass a pressure test.

looks awsome, but looks and performance numbers dont go hand and hand. [:D]

That's also a mitsu turbo.

Got any info on the manifold you are using?
