s2 xxxhp 90% ready

[aronmatic2]

The target is 14.7 but then it won't last long , it seems to be running good. Looking forward in seeing some cool time slips!

14.7 is good for no power, but on hard pressure, its need richer.
Like porkkis and jamo said, i will try on leaner, around 12-12.5.
I have egt gauge to check the temp.
thanks guys, i will try it anyway. maybe i get more hp-s.

[porkkis]

100% surely you can push more out of it when you dont flood it like that
Needless to say that listen for pingning while you make it leaner.

i allways listen for pinging,but my ecu has knock sensor. his ear is better than mine.

I know aron I was just kidding with the 14.7

Porkkis is a Suomi crazy guy.

i know you kidding, but not a bad idea


i replace the engine, tranny and diff mounts.
dont want to kill my tranny.

Cool. Still the GT30R? When do you get full boost? Around 4500 if I read your movie tacho right

[james_bufkin]

2 more days and ready to kill

Aron,
I like what you have done.
If I could make one quick suggestion. The 90deg Hose on the Intercooler exit. You might consider replacing that with an aluminum bend welded to the intercooler. Then use a regular straight hose section to connect the next pipe. I can't see that staying put. And I'm a big believer in linkages supplementing the hose clamps.

yes. that is the best turbo. i have .86a/r hotside on this stroker.
i have 2.0 bar on 3500. its goes like crazy. much different like on the video.

thanks james. yes. your right. i planed to put an aluminum pipe, but i cant get at that time.
can you tell me , what clamps you mean?
any pics?

thanks

The Audi Race cars use a thrust linkage. Greatly helps prevent boost leaks by taking the stress of the hose connections and clamps. Clamps, beads and hoses isn't a good way to hold pipe together under pressure. I've not had one single boost leak when using these linkages. Only Hoses and clamps is just a matter of time till one comes loose.

Well... after reading all these 22 pages of different opinions, comentaries, videos, photos, troubles, accidents... I might say just 3 words... OH MY GOD! Aronmatic, you did a superb job...and you did it by your self! Bud luck with those 2 accidents you had before, but drive carefully! hahaha Your car seems 2 be a lil' undriveable when you start from zero, power comes like a bunch! Take your lady to the circuit and tell us hows it goes!!!

thanks, but not exactly true. lot of my freinds and mechanics worked on this car. when i strated with this project, i didnt have any knowledge about s2. now, i know couple of things, but not much. i am learning every day. i am learning from my freinds and learning many things from this forum.(thanks for everyone )
i done lot of thing, but not all. i build a large garage on this year and i can do all work on this car and on my racecar.

the car is very driveable. i am using almost every day. my wife can go to shopping with it,if she wants. i can go with 15liter gasoline 100km, if i am not crazy(it happened 2 times).

[20vQC]

hehe well your boys know how to do it very well!!! I THOUGHT I know a lot the S2... but now I know that I don't know anything hahaha these guys from the forum know a LOT! And I appreciate the help they gived to me, and I'll need a lot more when my project will begin LOL Thanks you all guys!! Congrats again Aron!

we went to the dyno for finish the maping.

the day is started very bad. i broke 2 rear halfshafts.
i said that is ok. the car is strong.
i fixed and i thinked, better if i finish this day, go home.
no, its not me. lets go, finish the maping on dyno.
this was the worst idea today.
started to work on dyno. the car is almost flyed from the machine around 4000rpm.
the tires are spined over on 4400rpm.
on the third run, blown the engine.
i think the 2.2 bar was too high on 5500rpm for the 9.0 compression engine.
now i feeling very bad, but i am happy with the results.
i had 732 nm on 4000rpm and 512hp on 5400rpm.

[Acidburn]

Sorry to hear the engine blew, any idea what went in the end but will say one thing the results you was getting just beforehand was mental. Good luck with sorting it out and hope if it not anything too bad//hard to fix.

Sorry to hear that mate, but feckin A on those results 732 nm and 512 bhp on the same setup I'll be running except in the tall block

You've become my inspiration

I hope you fix it soon. I didn't realise you were running that high a compression!

Have you got a hi res pic of your RR print out?
