What Power Have You Achieved?

[Flukey]

Luke, my old car was running 281rwkw's with centre muffler removed and gutted cat. With these mods I was still able to run standard valve springs as the backpresure wasn't an issue. My car was running 12.2@116 with Xede well before the edit came along. I'd think it would have gone alot quicker with the same mods with edit.

Geea.

I remember. Does that exhaust stink with a gutted Cat?

Hi Luke, I have 285 rw with just centre muffler removed no hotdogs Trying to get the cat off to gut it but running in to problems. Will let you know how I get on when I take it in to get the car retuned

Hey Luke, no it does not smell, I had 294rwkw with the complete standard exhaust except I had Geeas gutted standard Cat.

I would suggest it was close it it's limit as sometimes under full throttle or backing off you could hear it struggling under pressure and sometimes would hesitate until it had cleared itself.

What also made it very obvious that it was the next restriction in my car, was I put the APS zorst on at that level and the car felt so much freer on acceleration and deceleration. The noises and pressure build up I had no longer existed.

I picked up 50rwhp with an SMB dump pipe and cat. A good hiflow cat should get you the numbers your looking for with an edit to match the better flow.

I've got edit, injectors and valve springs done for 257rwkw's @9psi - I cant get any more out of it.

I definately have restriction in the exhaust but dont want to spend $2K on a Difillipo or APS replacement.

I am hoping a hi-flo ( or gutted cat ) will get me closer to the 290kw's and perhaps an 11

JB, did you have standard valve springs at the time?
