290rwkw With A Gt3071r

[Guilt-Toy]

Yavus is the man.

[usmair]

he knows his stuff thats for sure

[Don Dada]

why do you need rpm?!? is your brain not capable of a simple conversion?

No hablo espanol

[Granthem]

Wow. Nice. Not too much different from my GT-RS really - except you make the 250ishrwkw it does at 5000rpm

[Adriano]

Have to wonder if it would make even more if boost didnt drop. Now tune it for e85 and make 320

[usmair]

yeh I wouldn't think it would make that much more even if boost remained constant through out the rev range...

I'm seriously considering E85... going to have to look into bigger injectors and fuel setup... but might just wait till I see some more digits in the savings account

[usmair]

haha yeh... blardi pricey HKSsssss

[R33 0wnerrr]

thanks

nope.. motor is unopened besides the Injectors

Mods are the generic mods..

PFC

Profec B

550cc injectors

Full 3" Exhaust...

custom dump

custom intake

apexi pod

BOV

z32 AFM

walbro pump

etc

Nice power....

But I thought z32 AFM cant read anything after 260rwkw? And how much psi were u running to get that sort of power?

z32s are ok for a little over 300rwkw usually

as per the dyno sheet attached on the first page of this thread, roughly 18-19psi fading down to about 17psi near redline.

[R33 0wnerrr]

Just wondering....what kind of head gasket do you need to run to be able to handle that much boost on stock internals?

[TiTAN]

the stock one.

[Harey]

also, what AR is your exhaust housing?

Did we get the answer to this?

Keen to hear if its the 0.63 or 0.82 housing!

[usmair]

pretty sure its .82 ... best to double check with GCG themselves re the part number mentioned above...

[badhairdave]

looks like -5023 with .82 response to me.

Also no boost control issues so can't be a .63 IW.

Nice results mate, It's actually a very similar curve to my sr with .63 3071

[Don Dada]

.... GCG rekon this new rear housing is 'original' Garrett and much more efficient...

I would say this is the key ingredient for the better output you have now and is typical power for both the original Garrett Gt3071 with the .82 rear end and the Hks Gt2835..... with the extra 10kw or so just being difference in dynos

[R33 0wnerrr]

the stock one.

I thought and so have read, that the stock head gasket needed replacing when boosting over 1 bar or so?

[Granthem]

Many people on this site are pushing 20psi or more through via the stock head gasket with no issues

[kb-r33]

nice power your running there, i was planning to get a turbo upgrade but unsure of what to get lol.

I thought and so have read, that the stock head gasket needed replacing when boosting over 1 bar or so?

and where have you read that? I smash 1.3bar into my motor day in and out, and it's unopened.
