Can you guru's in the forum tell me if I'm ok here.

Will I be ok up to 12 psi ??

Will I be ok to 14 psi ??

Here are the mods.

Street ported motor
Knights Sports ECU tuned for Intake & Exhaust
Non-Seq twin turbos
GReddy Main UD Pulley
K&N Drop in filter
Stock OEM Down Pipe (for boost control with no electronic boost controller at present)
3.75" Internal diameter Off Road Racing exhaust (mid pipe and cat back)
Stock everything else (injectors etc)

(Using 93 octane fuel with option to increase to 98 for race days.)

I'm presently running 5-7 psi as I've just broken in the motor (1300 miles on it) and I have not replaced the pills as yet to get the 10 psi.. planning to go with a Profec B instead of messing with pills.

Once I get the Profec B installed, can I remove the stock DP and run a 3" aftermarket DP instead and use to profec B to control boost or would removing the OEM DP put me into the LEAN ZONE ?!?!

I'm thinking 12 psi MAX would be wise but I'm wondering if I can make 14 psi with the present set up ???

Please advise,
3rdGen7

 

what's an oem downpipe? the only thing oem about that area is the stock precat...the downpipe replaces the stock pre cat (which is garbage and #1 cause of engine **** ups)

 

It all depends on if your Knightsports ECU is tuned for 12 or 14 psi. Almost all chipped ECUs are good for at least 14 psi, so you should be fine, however I'm not sure how non-seq will come into play there. To play it safe don't run more than 10psi until you get it on a dyno.

 

I'm from Trinidad ...all we have are BUTT DYNO's !!

I don't know how much boost the ECU is tuned for...but it is supposed to be tuned for intake and exhaust which means a little more fuel I guess.

 

Screw it, just pump it up to 20! JK.
