S2 with Precision CEA 6262 A/R 63 or 82 ?

[Audicoupe20V]

Hi

I`m searching for some results from a 20VT 2,2 with a 6262
At what rpm hit full boost .

A/R 62 or A/R 82

Sorry my english is bad

[Audicoupe20V]

it is possible at 4000 rpm 30 psi to have?

[MrVain]

Not at 4000... look at a 5858

[A80Avant]

4000rpm at which gear?
with what engine setup? stock head? ported? what exhaust system?

everything plays a role. I think i have read somewhere that its nothing near 4000rpm, more like 5000rpm on 3d gear. but i dont remember the specifics.

I use a 58/65 ar 58.
1 bar at 4700rpm 2bar at 5100rpm and 2.5 at 5300rpm. On the road it kicks in a little earlier
ported head, bigger exhaust valves, race cams +++ alltough I could get some more boost at lower rpms with different cams, but it looses power on the top end.

Hi
My 5857 A/R63 make in 4th gear 2,1 bar at 3600-7600 bevor he died

Now i can choose between a 5857 or 6262
if it makes at least 4500 2 bar then I'll take the 6262 otherwise I'll take back the 5857

My Setup:
2.2l
head is Ported but Std. Valves
ratio 8,4:1
revers Intake Mani
ABY Camshafts
3,5 " Exhaust

What power do you make with your current setup?

I dont no
The Car was not matched.
It runns with a Software from an S2 with GT 3076 with save ignition timing an 2 bar boost.

0-100 Km/h 4.05 sec.
(62.13mph)

100-200 kmh 8.1 sec.
(62.13-124.27mph)

0-200kmh 12.36 sec.
(124.27mph)

That sounds about right to what I would expect. That turbo is pretty close to a 3076 so it sounds good enough.
I get on the similar setup the same boost curves, maybe 200rpm later.

Are you sure you would loose power? With a "small" 58/65 I guess the turbo is maxed long before race type cams are needed. 99% sure your car would be faster with not more then 7A type cams.

I'd like to know what results you get. I'm building up a stroker 2.6L engine with the same Precision 6262.

[quattrofrank]

Maybe I shall try 7a cams. Have tried oem 3b, jonus cams, krb and km cams.

I drive with a precision 5858 63 a/r

full boost (2bar) at 3000 rpm. But it´s also a strocker 2,6

I will go for the 5857 it´s a nice street setup
