View Full Version : big turbo feels like what?

For those of you BT people... what would a big turbo feel like compared to a K04?

My car went from bone stock to a fully tuned K04 setup, and it was an amazing difference. Will a BT be the same type of feeling, or is it more high-rpm power?

I have fairly bad turbo lag as it is now, i imagine it gets worse with a BT.

just curious...

its definately more higher rpm power. I'm sure your setup is super torquey

It actually doesn't feel as strong down low - it is constant power vs. a surge of power

A KO4 is like having foreplay but she sends you home before the big grand finally. Having a Big turbo is skipping the foreplay and going straight to the Grand Finally.

depends what turbo you get. if you want spool close to the ko4, you get a 28rs .64 or a t3 super60, full boost by 3200-3300 and much more up top than the little ko4

K04 feels like you are going warp 9 due to the torque spike.

BT feels like you are doing 40 when you are actually doing warp 9. The onset of power is really smooth.

And that turbo lag thing? Doesn't really exist if you know how to drive properly.

yea, BT setup is verry smooth.

I really hope you dont think your K04 is laggy! The bigger turbo I go, the more I like the powerband. Winston described it perfectly, feels like your going 40 and granny driving until you look down at the speedo and its booking around the dial like no ones business! Smooth and constant powerband FTW!

winston@podi.ca
04-15-2008, 07:46 PM
What happens when I tap the throttle in 2nd gear at 4000rpm with my BT setup is just ridiculous.

Once that turbo is spooled there is no lag. Just launch.

i would never call a BT setup smooth..
the onset of boost is smooth, gradual and linear, but when it hits full boost, it hits much harder and produces much more torque than the ko4...
The ko4 hits early with early torque spike and low power, but is definitely much smoother than anything else bigger

The power/torque onset is smoother, not the car itself (or the tach) lol

bernB5
04-15-2008, 08:09 PM
i still won't say smoother! maybe laggier, and takes longer to reach that inital thrown into seat feeling, more gradual.
im not trying to argue lol the word smooth just kind of bothers me tonight, when describing powerbands

biketsai

Well once your in the powerband, its all the same shit from there on

bernB5

Well once your in the powerband, its all the same shit from there on

you're right.. being in the powerband of a 220whp k04 feels exactly like the powerband of a 400whp 30r...

my t3/t4 was a tad bit laggy but when boost hit ~19psi it was like the whole car came alive and reared up on its back tires and just pulled like a mofo. The thing was that after about a month of that, I wanted MOAR!!!!

In other words, a K04 is like you didn't bring enough money and had to cut the hour short....

Mike, do you run a completely stock 5spd Trans? I'm worried about 3rd gear, everyone making more than 350whp has blown it, including myself a few months ago (n0t everyone but a handfull)..

........ hahaha thats the thing about these little 1.8ts, even if the turbo spools @ 4k (BTs & Bats), it still doesn't get real fast until 4.5 - 5k.........

I wonder if some mid-range cams would help with that.

sean1.8t
04-16-2008, 11:20 AM
yeah, after i posted i realized the info was there. but i was too lazy to edit..

but a 30r should hit 20lbs before 5k i would think ?

bernB5
04-16-2008, 11:54 AM
it hit 25lbs at 4000-4100

Thats happens because the CFM doesn't start to really increase till after the turbo hits the boost you wish to run. The RPM the boost hits is the boost threshold, the time between that and the time you feel the power is boost lag.

sean1.8t
04-16-2008, 03:29 PM

O RLY?

cause is it just me, or does it sound like your WG doesn't open up til a little after 5k rpms?

i would like to see a video of a 1.8t pushing a 30r to 25lbs by ~4000rpms.. so if you can, please post on. cause that will difinately convince me to upgrade to BAT

bernB5
04-16-2008, 03:41 PM
it's just you.. you're judging that from 1st gear, and in the vid, i didn't even go WOT til about 4500.. 1st gear has very little load..
In two weeks I'll take a vid once the car is up and running again and I'll floor it from 3000rpm in 3rd gear..
4000-4100 is really not too crazy..

audiness
04-16-2008, 05:47 PM
Wow... this turned out to be a good conversation. I guess what i'm feeling is torque spike, because i am definetly boosting, but for a second or two i get nothing and then all of the sudden, BAM .... i hit the powerband and I'm hauling ass.

I haven't decided to go BT yet (mostly due to lack of funds) but it's a possibility if the right setup shows up in the classifieds [cool]

well actually, in first gear, you your WG didn't open til almost 6k.. so i was going off of 2nd gear lag. and i couln't really judge 3rd..

but sounds good man. can't wait to see a vid.. there are plenty of BT vids out there. but not too many BAT vids.. especially in car

Don Supreme
04-16-2008, 06:07 PM
^ He really didn't do a full low rpm pull in that video......

Just a tap in 1st

and a slow roll in on second.

bernB5
04-16-2008, 06:15 PM
thanks for backing me up Don :)
I PROMISE to have a vid up of in-car, driving around and an easy view of the tach from a 3rd gear roll so you can see exactly what's going on.

There woudldn't have been any respool time in 2nd if I was really shifting hard, I didn't rev out 1st at all AND I was spinning, which is why when it goes to 2nd, the wastegate doesn't open immediately.

221whp and 195ft/lbs of torque! on 24psi and a BETTER tune haha. I floored it in 2nd getting onto the highway with my wheel slightly turned and the car just starting drifting. amazing what 200whp does haha

I think I may stepping up to a 30r. Who's buying my gt3071r? PM me, its coming off in a few weeks.

Anyways....you wanna know what a BT/BAT feels like? Follow this 10 step process

Step 1 - Reach in back pocket and remove wallet

Step 2 - Use a set of calipers to measure thickness

Step 3 - Remove paper form of money

Step 4 - Remove plastic form of money

Step 5 - Fold wallet and measure

Step 6 - Put wallet back in your back pocket

Step 7 - Sit on a wooden chair

Step 8 - Verify that the wallet is indeed significantly thinner

IMHO,a Big turbo with the correct mods feels like a semi stock B5 until 4000 rpm's.
When I was younger I use to drive a AE101 Corolla GT and that has less power NA that what the Audi has turbocharged and to me those felt rather nice so driving around a ~140whp - 180whp Audi A4 until 4000 rpm's is not that bad.I dont get why people bolt on GT2871R's onto there motors.I think I have sold probably 1 to a customer.I always try to sell them on anything as big or bigger than a GT3071R.Of course a 2.0L with a GT3082R is to me the perfect turbo for a DD audi A4.500whp on tap and off tap it drives just as nice....

lag is only what you make of it.

Don Supreme
04-17-2008, 05:10 AM
^ Indeed.

Sometimes I think about downgrading to a 2871 or something, but I have never seen an A4 making any real power before 4k any dam way (with a BT (2871+)).

Additionally, I have been thinking the same dam thing about lag. I have been driving around my wife's car with a 130 Hp toyota engine, and it does just fine..... EVEN @ 3.5K , the 35r with only 5-6 PSI... HAS to be making more power than that thing...

I'll agree with that. Until boost hit, my car was like a n/a 1.8. Perfect for around town driving/traffic etc...It was the proverbial wolf in sheep's clothing.

Making more tq then that which is what moves the car.

The #'s on my car at the wheels
3500 = 100hp and 140tq
4000 = 125hp and 175tq
Those #'s are plenty good enough for just cruising around the streets. Now after that point is when it gets fun.

4500 = 200hp and 240tq
5000 = 380hp and 390tq ( 180hp and 150 tq jump in 500 rpm)[eek]
5500 = 450hp and 420tq
7000 = 555hp and 415tq (355hp gain in 2500 rpm)

140 ft/lbs @ the wheels is more power than most 1.8 toyota engines make @ the crank and last I checked there are TONS of Corollas and the like running around happy as can be.

P.S. Even the Lotus Elise, which sports a hopped up toyota engine makes 138 ft/lbs @ the crank.......... I know the car is half the weight, but you get the point.

Back to the 1st page for a minute, for you ko4 guys wondering what it feels like, floor your car in 2nd gear, thats what a BT feels like in 3rd gear and a BAT feels like in 4th gear. I went from bone stock to 2871elim because i knew i wouldent be happy anywhere in between, now ive been a gt3071 for a year. Im fully spooled at 3600rpm(22psi), but the greddy profec b spec 2 EBC helps out with that, im tapp tuned 100% stock 1.8t transmission and i have not had any problems, im right around 350-360awhp with my alcohol kit at 22-23psi. I will try and post a video up too.

Have you dyno'd your car? Only asking because the last A4 1.8t guy running a GT3071r at even more boost on 90% meth and 10% water thought he would be close to 350-360 whp ended up still under 300 and that was a FWD car.

Have you dyno'd your car? Only asking because the last A4 1.8t guy running a GT3071r at even more boost on 90% meth and 10% water thought he would be close to 350-360 whp ended up still under 300 and that was a FWD car.

You statement is that he dynoed @ EVEN MORE BOOST - So your statement is false.

haha no need for an arguement! [:)]

I dyno'd on 18psi, that was with 93 octane and blue washer fluid (no meth mix like I run now), T6 on SPS and I did 264fwhp/251fwtq, same dyno I did 298fwhp/295fwtq with my GTRS, 24psi, 93/100 mix, T9 on SPS with 0's for CF's.

I will have a completed file in the next 2-3weeks, then Ill make it to the dyno! Should have a beta file hopefully today, if not Monday for my setup! [:)]

My guess would be Chris and Nick of REVO, since he has been trying to get the special GT30 630cc 8500 rpm file that they do for David at Eurocode which was something david paid for by flying Revo out to socal to do.

Nope different file, was started for Bobby @ DTC Designs and remains unfinished. It is for a 3076R, 630cc injectors, No MAF. I inquired about getting a few extra codes removed from it so I forwarded them to Chris yesterday, he was going to get them removed from the systems check and send me the file. It is written for my ECU box but for a 6 speed, so the cruise will not work and few other small things, but they want to get the file correct first, then make adjustments for feature comforts. Both said it would be extremely "rough" at first but if I logged what they needed the would get it corrected and updated within a few weeks as well as the "features" working. Ive yet to bow to David's "special abilites" and am managing to get it done myself (and for MY car) thanks ...

Sounds like a new base map but pretty close to what david already offers which is also tuned for no maf.

No one said you had to bow to david, but the fact is that you just didn't want to have to pay david for something he paid very good money to get done and have exclusive rights on.


Hope the tune you are getting works out well.

Back to the original question, this vid should help illustrate the difference in powerbands between two turbo sizes.

I guess you haven't seen the Autobahn supra that goes 0-228 in a mile and about 20 seconds. The video feels like its making a run for take off. [>_<]

sometimes too me. a BT car feels like, "damn, why didn't i just get a stage 3 S4?"

but then i think, this car is A LOT easier(more fun too) to work on and hot damn if i didn't get 34 MPG on my last tank!

thanks sean, you just answered a question that i didn't even have to ask. i was curious as to what's more fun all around, a BT/BAT a4 or chipped/st3 S4.

i've never driven a stage 3 s4... but, I've driven a stage 2++ (all bolt ons, stock turbos)
and I've gotta be honest. Having such early torque and 330+whp to redline feels awesome, the top end power is where I'd want more. I think an s4 with k04's or rs6 turbos would definitely be more fun than any BAT a4, more driveable in all situations as well.
If my motor blows, I might switch over to the 2.7 and some 28r's.. we can dream!

It needs to have more low end tq because of the 500+ extra pounds. Sorry to tell you but a S4 with GT's doesn't have all that much low end tq and would have just as much lag as your A4 has right now if not more, that setup doesn't fully kick in till after 5k rpm.

yeah, but you don't have to have 28rs'. you can put on some gt2554's or gt2560's for a bit less lag and still have gobbs of power[granted you need to throw in rods, and usually build the heads, but if you have the means, no problem] to compare those with the 1.8t. it's like having gt35r power with a gt2871r spool! it may be heavier, up front, but you only notice it in the turns. and lets face it, the A4 is no super achiever in the turns either[:(]

the only great thing you can use to compare the 2 is timeslips..

there has to be over 500 S4's in the 12s. and maybe 40 A4's?

30 s4's in the 11s, maybe 3 A4's?

30 s4's in the 11s, maybe 3 A4's?



I know of 4 A4's in the 11's. Ctapp, Lucas, ATP employee and me.


10's = 2 S4's and 2 A4's in North America.

Lets also remember it cost more to buy a S4 and twice as much money to get it into the 11's/10's as it does to do the same with the A4.


The GT28r on the S4 is still going to have way more lag then any of the K04 setups. The lag between a GT28r and GT28rs on a 1.8t isn't all that much. Yes a set of GT28's on a S4 might be like having 1 GT35r on a 1.8t, but then your also paying twice the price for that power. If hp is the goal how does paying twice the price become "better"? [confused]


Weight is weight, less weight can make a huge difference when using the power. This is exactly why people use the power to weight ratio.

Weights with driver.
2900 lbs S4 making 450 whp = 15.52 whp/100 lbs
4000 lbs S4 making 550 whp = 13.75 whp/100 lbs
4000 lbs S4 making 600 whp = 15.00 whp/100 lbs
4000 lbs S4 making 650 whp = 16.25 whp/100 lbs
4000 lbs S4 making 750 whp = 18.75 whp/100 lbs

3400 lbs A4 making 450 whp = 13.23 whp/100 lbs
3400 lbs A4 making 500 whp = 14.71 whp/100 lbs
3400 lbs A4 making 600 whp = 17.14 whp/100 lbs
3000 lbs A4 making 600 whp = 20.00 whp/100 lbs

i wasn't talking about money. if that were the case, i don't know why we'd be talking about Audi's in general [:p]

im just saying, if money wasn't an option(and the VR-t swap wasn't around) then the S4 just wins hands down. there's no replacement for displacement in this case 2 larger turbo's are always greater than 1 larger turbo

Damn, i figured there was a ton of b6 a4's making over 300whp, stage 3 s4's dont impress me that much, i raced my friends before he sold his, he put 3-4 cars on me from 40-120mph, and that was before i had my alcohol kit, his s4 was always in the shop, his tranny went out too, a4 stuff is so cheap compared to a s4, but thats just me, everyone has a friend with a fast supra lol, my friend has a t76 750ish whp, when he is on it you can even blink, its got more of a adrenaline rush than bunji jumping haha.
