332.6kw

Wouldn't the problem be your wastegate?

Wastgate "bleed off" can cause your boost levels to spike when to much hot exaust gas is being re-directed back into the tubine, rarther than out the internal wastgate,this could be due to the actuator being to heavy?

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

hey all,

just thought I'd drop my dyno sheets cause I made it into the 300+ club

Just a few things I wanna ask some people...

Firstly, I was expecting around 350+rwkw... but for some reason the boost was spiking all over the place when it got to about 14psi. 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

What's happening with the cooler inlet/outlet? Has it been modded yet??

[Jeremy]

haha that's arright tom... yeh its droped a lot of jaws lately when people go for a spin in it.

A few updates:

1. 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 :)

[Dirty32]

Must of been travelling at some speed if it was full stick in 6th lol!!!

[Jeremy]

within the WA speed limits of course. I dont condone dangerous driving

[TH0MM0]

if this is a helping hand. 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

[ysoslo]

that's good work mate, nice power and sounds like you have more in it !
