He basically said the catback is restricting it. I thought I should be cracking 300 easy with these mods Link to comment Share on other sites More sharing options...

Ive got new atomik heavy duty valve springs recently fitted. I have spent about 10k in the last month on it. Link to comment Share on other sites More sharing options...

Future Donating Members 116 Member For: 13y 1m 19d Gender: Male Location: Brisbane Posted 05/06/14 01:08 PM Share Posted 05/06/14 01:08 PM Yeah it was just on dyno 2 days ago.Im concerned as changing the exhaust wont make the difference im chasing the only other stuff to do is crossover pipe and intake plenum plus a surge tank. That will be down the track but I shouldnt be having to go that far for just 300 surely Link to comment Share on other sites More sharing options...

Plenum is good for torque and surge is good to maintain fuel pressure.If cash is tight, just throw on a redback twin 2.5 cat back, that will be good for high 300s , and sort the exhaust out.
