i'm running 330 hp on stock twins and stock boost. i wanna upgrade my turbos into another set of better twins...i see a lot of nice big single turbo conversions, but prefer keeping it twin. anyone ever done a twin turbo upgrade that can give me some heads up on what i am dealing with...or where to start looking.

Search here for BNR Stage 3s....

 

330 on stock twins and stock boost? you must be one lucky guy...I dont think anybody is at that level with the stock twins on stock boost..

 

haha 330 eh ? you da man !

 

Like rynberg said, i'd look into the BNR's.

Can be run non-seq or seq.

 

how exactly did you calculate 330 on stock twins / stock boost?

is this an actual dyno number?

 

Mine is running at 370bhp with stock internals.

 

this is wat i have

Er yeah, you might be making 330 at the flywheel, but no way at the rear wheels. Not at stock boost. A well tuned fully modded twin car with a streetport will generally make 300-310 rwhp at stock boost.

 

Stock motor, stock turbos @ 10 psi producing 330 at the wheels? I don't think so.

That's 390 flywheel hp from a motor that made 255 stock, with nothing more that breathing-enhancing bolt ons? nope.

Put it this way: the best numbers i've seen for ANY car using ANY sequential derivitive of the twin turbos is maybe 385 rwhp @ 15 psi on a streetported motor. Subtract 10 hp per/ # of boost, and you're looking at 335 @ 10 psi. If you're pulling that with stock motor and turbos, I suggest you KEEP whatever turbos you have, because they are GOLD.

 

Just FYI, he never mentioned rwhp.

 

noticed that myself...

 

i would post my dyno chart if i had a scanner..

 

so is 10 psi stock....or is it lower than that???

 

i would not touch your turbos. first rule of thumb dont fix it if it aint broke. if u can run that number now why change a perfectly good turbo setup. second how does that n1 exhaust sound.

 

see for yourself...imho i love it nice deep throaty sound

which setup twin or single,,...?

 

10 PSI is stock.

 

i'd thought so

 

If that's 330 rwhp @ 10 psi, don't touch a bloody thing!

 

ok enough said then i am pursuaded..thanks all
