dont really know to much about these cars or what power levels are capable from them so I thought id ask here.

ba xr6turbo with the following mods

-valve springs

-siemens 60lb injectors

-actuator upgrade/ flapper mod

-walbro fuel pump

-xforce 4", twin 2 1/2 system

-custom tuned at HPF

-standard intercooler

using 98oct fuel it made 277.5 rwkw on 15psi

just wondering if I should be expecting alot more from those mods or if it sounds about right.

before I got the injectors, fuel pump n actuator fitted, the car felt faster wen it spiked to 15psi, than it does now tuned to 15psi.

any help would be appreciated.

Sounds a little low for 15 PSI and all those mods

My cars making about that on 10 psi

I don't have an actuator upgrade or flapper mod done and no upgraded fuel pump

I have all your other mods and a Rapid cooler and making 290 @ 12psi

The standard cooler & piping will be a major restriction as will the standard cat if it's still in place. Have you got a 4" dump & cat or just dump??

I was just about to ask if using the stock cooler and stock cold air intake would be the reason why power levels are down that much

and its a full xforce system, cats n all, 4" dump

yeah its the stock cooler for sure!!

my sedan makes 265rwk with only a custom 10psi tune and the mods in the signiture...

who tuned it??

Sounds similer to mine. Iv got same mods but iv got PWR cooler. I got 284rwk at 16psi. I was told it was my standard pipe work and cooler to blame.

284 @ 16 psi :s geez

Mine was making 300+ @ 12 with just injectors and cat/dump

My BF was making 280 rwkw with only Siemens Deka injectors and a typhoon cold air intake, at 10-11 psi measured on a 40 degree day :D

That certainly sounds low on the power figures mate, but like mentioned above its probably limited by the stock cooler..etc.

it will probably feel heaps quicker than the previous power though, that's for sure
