LOL yeah, I'll bet that made them all jump

One way to find out geezer. Wind the boost right up (on Sals car)sigpic

The commonly known limit on an S2 crank is around 700Nm. way to go there, 650Nm at 7000 RPM means 640-ish HP and 7500 RPM would be 680 HP...
So there's some margin left there.
The engine didn't go in a very spectacular way, but the main bearing caps jumped off
oh well... I know it's not my fault and I had done nothing wrong (EGTs were 860 before the turbo, no pinging or retarding detected/logged, AFR was solid 12.2:1), and quite honestly, yesterday's 515 HP/550Nm would have been enough for me... only the owner wanted more torque...

hehe! well fine with ou ah!
so it's safe o say that he 5 cil are stronger! and better built for theze extreme amounts of bhp and torque>?(wich i always found logic)Comment

Mihnea, any idea what size A/R hot side he was using on that GT35R?Mark - ModdedComment

1. What's the weight of the car? Mine does 100-195(measured with g-tech) in 8 sec with 1650kg (with driver). Havn't dynoed it yet so nice to get a hint if the g-tech is accurateOriginally posted by Mihnea!
1. The car takes 8 secs from 100 to 200 km/h on the GPS. So I guess the power/torque figures are about right.
2. , but oh well, at least someone found out where the limit is on a stock 210HP S3 crank...
2. Is the S3 crank forged? Someone once told me that only the first 1.8T crank's where forged (-95-96) Don't know if it's true, but if it is, then an early crank or another(2.0 or maybe TDI) forged crank would be a smart move yes.Comment

Car weight is about 1450 kgs, maybe a little more for this one because of FMIC and some other stuff...
I know that a 225 HP TT crank is indeed forged. I have no clue for the 210 HP S3 one...
The guy is going to get a 2.0l kit from Dahlback/MTM and there will be no more problems.
GTech is not that accurate IMHO. Even when you set everything right, 1/4 mile times and speeds are off most often. BTDT....
The dyno IS accurate. A stock TT 225 dynoed 224HP/282Nm (factory rating 225HP/280Nm) yesterday on the very same dyno.

yes my s2 has done 363tkm,engine only 163tkm,it´s a rip off i now,when i bought my s3 in de i payed 29300euro,drove 17000tkm,had 2 big service diff oil and plugs,2 times polish at the dealers(iám nut iknow buti wanted it to be perfekt for when i could take it home to dk service every 10tkm),had to sell it to the same dealer who only gave me 19300euro,when i sold it back 6-7months later 
,but i had fun in that car best car i´ve ever had 
,**** the money those s3´s handle superb.

the first model´s (s3)210 version where only 1295,mine was 225 with can-bus,and only minus was no navi and autopilot.Comment

Rix, WTF? I've heard some stories of 210HP S3s not being quattro, although I've tested and tuned a couple myself and it's hard to believe, otherwise, I can't figure out why the 225 with can-bus is SO heavy...'98 Silver Grey 2.7T S4, dual 2.75" turbo back exhaust with no cats, FMIC, BIG injectors, 10 Bar motorsport fuel pump, modded RS4 turbos, tubular exhaust manifolds, custom intakes, RS4 MAF, Bilstein PSS9, H&R ARBs, 19" BBS CH, custom remap, 511 BHP/505ft-lbs

they are all quattro(haldex),there must be ekstra protection,all the ekstras weight alot som off the first model didn´t have fog light´s reverse sensor,i had abblend bare speigel (all 3 of them),symphony radio(big),they all have zenon climate control heated seat´s and recaro,some in cloth,some like mine black leather and blue alcatare,the mirrors weigh a ton hand polish alu.other then that i don´t.
it must be that ekstra 15hp and 10nm,that gives the weight diff.

All S-cars have been and are quattro. Period. Full stop.-Comment

I know and will soon dyno it both to get accurate HK/Nm and to fine tune it(and rise the boost from 1barOriginally posted by Mihnea )
About the 2.0 kit : Is it a 2.0 tall block or?
Cheers,
