Mr Man Mad Scientist Member 816 Member For: 19y 11m 18d Gender: Male Location: Vic Posted 14/07/11 12:58 PM Share Posted 14/07/11 12:58 PM From memory a few people on here over the years have made similar numbers with similar boost at HPF. Maybe its because their dyno reads lower, but really rwkw is just a number... As long as you're happy with the car and the way it drives is what matters, if not then get it tuned elsewhere that will give you the rwkw number you're after Link to comment Share on other sites More sharing options...

Trying to cram 17psi through a pin hole ain't gonna make power.He doesn't have the stock UBP. He has a gT2 HDI... They are good for 350rwkw +... they run the cold side out the passengers side... And up in front of the engine back up to the crossover...Bring it to another dyno... I had 350 admittedly with shorter cooler piping, however, it was at 15psi... And I had stock exhaust with high flowed cat... Link to comment Share on other sites More sharing options...
Jez89 Donating Members 30 Member For: 14y 5m 15d Posted 14/07/11 09:36 PM Author Share Posted 14/07/11 09:36 PM Cheers for the feedback guys. I have run it on another dyno not long after HPF just to compare because I thought it was low and got about the same rwkw. I'm not chasing a number or anything I just want to make sure I'm getting the power I should be safely. I also ran it on another dyno just to check AFR's and boost because the only graph I got off HPF was the one I posted.... not sure why some things have to be so f-ing hard sometimes... . Anyway I will be definately going to Pitlane as it sounds like everyone that goes there comes out pretty happy and actually knows what their car is doing. It's just a pain in the ass because I live in Albury which is far away from pitlane and a proper drag strip. Hopefully in the next month or 2 I might get them to have a look at it.

The internal diameter of those 3" tips you see is only about 1 3/4" not even 2". I measured them a while ago using a telescopic guage in there.

In 4th gear 120kph - 3625rpm 136-4121 152 -4606 168-5090 184-5575.So looking at your graph there is very little extra power from 4121 - 4606 and then it lays over. Something isnt quite right.
