Guest Guests Posted 21/10/08 02:11 PM Share Posted 21/10/08 02:11 PM Nice work.... I have a similar setup and I am getting 335rwkw... I would suggest it may be your wastegate/flapper?I dont have the exhaust, but may do this eventually.335 and 350 wont be much different... 335 may be better for a 1/4 time, as you get so much wheel spin and you would really only make that at 5000+rpm, which is when you are shifting anyway.A good tune will see max power reached a little before 5000rpm & held for a while provided all the components are upto the task Link to comment Share on other sites More sharing options...

I had the actuator changed to a 12pound one for xr6turbo developments, and had the valve springs done etc etc. The guys at BPT reckon it may be my boost solenoid is sticking that's why it was spiking? They controlled it relativly well after about 4 hours on the dyno. But they said if they can get that sorted they should see more power.. any1 with any ideas? Also, My stage 3 PW cooler I put on it has only the stock inlet/outlet sizes so they said that would of been restricting flow which is why I probally didnt get to the 350+ mark...they are gonna re-engineer the cooler to bigger inlet/outlet sizes so hopefully that will fix the flow up a bit.Other than that I was resonably happy with the power and 900+Nm of torque which really made the difference.Also had the Malwood short shifter fitted... feels great a you can slam it into gears.going to take it down to kwinnana this next wednesday to see wat time she runs... hopefully I can get my mickey thompsons in time.Jeremy just took me for a run in his beast today man that has some serious grunt it has the "OH sh*t " factor thanks mate Link to comment Share on other sites More sharing options...
Guest Guests Posted 28/10/08 03:42 AM Share Posted 28/10/08 03:42 AM What's happening with the cooler inlet/outlet? Has it been modded yet?? Link to comment Share on other sites More sharing options...

Did the boost solenoid trick and didnt really fix the boost problem.. so im more looking at the wastegate/flapper mod now. Although it did come on boost a little more earlier in the rev range.2. Yeh I had a chat to the guys at BPT but they are flat out... probally going to have the inlet/outlet job done first before the flapper/wastegate job.. around early december. I'm going to get BPT to give it a go with the inlet/oulet job and re-tune.. see what they can produce..then if its still not around 350+ I will take on simons advice to get the flapper/wastegate mod done and give him a tune on the car. theres a lot of hype around weather or not this mod should be done and if its needed.. from what I know its more of a tunning thing rather than hp gains.Another little thing I like to add is that I went against a Blue R34 GTR V-Spec yesterday on the freeway.. had the N1 exhaust and by the sound of it had some work done to it. he couldnt pull away from me as hard as he was trying and I gained a car length on him when I was in full swing in 6th gear.... geeeeezz that made my day :) Link to comment Share on other sites More sharing options...

I have a stock rear housing that I planned to send away to get external gated. you can use mine to get ported, then do the swap on your car. and give me your housing when done..just a thought Link to comment Share on other sites More sharing options...
