GURUMAN'S final quest for 9 seconds, V6 single turbo style...

[antoanS4]

No way in hell is 93+W/M as good or better than E85. I've seen cars make almost as much power on E85 as Q16. My buddies Supra made like 860 on Q16 and like 830 on E85. Is 30 hp worth $7+ more a gallon?

I would love to get tuned for E85, you can run insane amounts of timing on it. Not to mention it burns colder. And is like $3 a gallon.

EPL does E85, do it

Good luck

But you do realize that your pistons have dual valve notches, right?

[GURUMAN]

I guess my engine builder will figure this all by himself

help me understand your point ?

[GURUMAN]

my old engine had the same...

[Reich]

the notch in the piston is to clear the midle intake valve. I don't see any issue here.

I think he is referring to the combination of quench pads and a piston with valve relief.

[pete@integrated]

Exactly, right where your extra valve relief is in the piston, is where the quench pad is. I'm sure it's not ALL covered by the valve relief, but that spare valve relief will certainly negate most of the effectiveness of the quench pad. I would suspect this is the reason audi deleted them in the first place.

So why do they do it? Laziness on the installers part? They don't want someone to put them on backwards? Honestly if you are building an engine, how would you not know to put the relief side on the side with the intake valve?

I'd always wondered why they did clearanced both sides; we just did some pistons for a 3.0L build with CAT cams and VVT. They had to be seriously notched in order to clear.

yo man - i love this build. congrats and keep chugging!

What do you do when you want to run more agressive cams then ?

That's actually a duplicate of the stock piston top geometry. Those reliefs don't line up to anything, just like the oil jet reliefs in the piston skirts. Look at some 1.8T pistons and compare what valve reliefs look like when placed in the correct position. That being said generally these pistons don't need any valve relief at all.

Sounds good. I got mistaken because of the area where it is. Looks close to a valve relief. Ohh well thanks.

[GURUMAN]

Just bought Salts custom sheetmetal intake manfold today.

I'm very excited about going forward with the engine, 1000 bhp mark seems to become more achievable as I see progress.

[4ringsonthagril]

Gorgeous.

[Dan[FN]6262]

I got to meet him. He is definitely one of the coolest people that I've met.

[Drizzen]

Whats turbo is that?

[GURUMAN]

not mine, Salts s375

mine will be a bit smaller, precision 6765

[Reich]

Very nice Intake manifold.

[Daniel360]

top notch.....!

[Mantis]

Nice pick up, I offered to buy it from him a month ago, I guess he likes you better

[Peacob]

mother of god.

[beemercer]

Yes! Competition is always good, I know you are familiar with what it takes to build a fast car so I can't wait to see the outcome! When are you hoping to have this thing on the 1320??

[GURUMAN]

Jeff, you are the reason I aborted my project on the LS conversion.

My goal is to equal or better what you did achieve with the VR car

Engine should go on Unitronic's DTS dyno in 3 weeks from now.

1320 in June

[Max@034]

Wow, that manifold is gorgeous indeed... If any more of those are available, let me know, jeez! I've been waiting months for my RS4 and my motor is essentially ready to go in.

only problem is at least 4 x Rs4 manifold

Talk to Javad so he makes some with his beautiful machines !

[Max@034]

Hahaha yeah. I already pushed that one pretty hard awhile ago; even did a fair amount of design work into it. The cost was excessive!!!

Flanges are easy since we already have the phenolic's program, but the runners would be difficult and time consuming. =(

That mani wouldn't fit if you're looking to run twin turbos instead of single, with a y-pipe in the standard position, non-custom bi-pipes, and the throttle body on the same plane as stock. It extends too far up and forward. It's perfect for a custom single turbo setup though! Keep your eyes open for a relatively decent priced performance IM option in the next couple of months

Guru, do you know what the plenum volume of that IM is? Are the runners for the standard big ports, or hogged out big port heads?

For my A4 V6 and not my S4. I shouldn't have combined statements lol.

[jibberjive]

Yeah, forgot about that one ha. If you want to shell out for it, I could design and make you one for your single. With those straight runners and relatively orthagonal faces, it would be 10x easier than these others that I'm dealing with. Just let me know.

[gearhead1186]

i wouldnt mind a "hi-rise" intake like that for a twin turbo application. IMO, when your willing to throw down the money for a sheet-metal intake, rerouting the Y pipe and extending the bipipes are small sacrifices for the easier design of a hi-rise. The y pipe can be ran down the sides of a hi-rise intake instead of over the top. just thinking out loud of course.

Micheal, don't worry and don't make assumptions what's best or not. I have the full paperwork and flow studies of this baby. Salts did it the right way trust me.

Do you honnestly think we would run and make small ports ?

[cjk]

Bad ass intake mani you got there! Salts is a cool dude who knows his shite

haha...defintely not!

[GURUMAN]

FAW loves me ! check ou QW

[csosnowski]

geez what is the exhaust size on the hot side of that thing (salts)? 3"+?

guru, will you be running a similar size exh? specs on exh, external wg? (sometimes im dumb lol)

Eh? I'm not worrying nor making any assumptions about anything, I just thought Max was saying he wanted one like that for his twin GT S4, so I was telling him some of the design difficulties I've found for doing a big IM on a twin setup (which obviously aren't issues with you with your completely custom balls-out single setup). And I know that intake is very well analyzed and designed, as Salts did the analysis for an MEEN school project or whatever. I shot him a PM a couple of months ago to chat with him about it, but got no response. Sick mani either way.

And I know you're not running that on small ports (you already mentioned and pictured the 2.8's, and that would just be retarded anyways), rather I was curious if the shaping of your heads meant that you ported and changed the size of the intake opening at the interface (ie stock 2.8 big port, or ported 2.8 bigger port).

If you have any requests or design ideas to throw around, I'm all ears (and the time is now, if ever). How do you propose to run a single MAF with the Y-pipes along the side of the plenum and keep them the same length (and there would be other obstacles there, like the aftermarket fuel rails)? Split directly behind the plenum somehow, where a single turbo would be? It's tough, because not everyone who is willing to spend the money on a new IM would be stoked to sell their shiny new ARD bipipes (or whatever) and run a completely new and custom fabricated whole intake tract. But if you have some cool ideas though, I'd love to hear them
