I just got off the phone to my engine tuner.

Had custom intake fitted which was for sale on here, car has just made 295 rwhp.

Previous best was 245 rwhp, this is on a Dyno Dynamics, so although it might not sound much to you US guys, our dynos do read 15-20% less than Dyno Jets etc which would put it up around the 340 rwhp mark.

Will write up a bit later after I have driven the car to compare the differences

Yeah thats the final tune, I will know more when I head down the coast to pick it up this arvo.

This would be equal to around 354 rwhp on a dynojet, going on the loss difference

How do the dyno dynamics compare to a Mustang dyno. Because the mustangs dyno about 10% less than a dynojet I think? And the mustang is what I did all my runs on.

Also, DAMN, you gained over 50-60 rear wheel horsepower!!!

What diff gearing are you gonna use next? I remember your video entering the freeway. You went through the gears and when you reached 5th, you weren't going very fast.
Reminded me of my REPU with its 4.625.

That was when I was running in the engine, hardly reving it

It has plenty of top end, don't worry about that

Here's a video of top end going, 4th gear, had to back off, but it was well over 200 km/h

This is before the new intake too (50 rwhp less)

Have the coolant and oil temps gone up any? What is your normal temp range?

I'm runnning stock guages, it is all staying the same as before though

You lose a bit of low end, with the tripple tb's it is very responsive, a bit harder to drive on light throttle than before.

But the mid & top end difference is huge, my engine builder is a well know drag racer and rotary shop over here, he's stating it would run 120 mph down the 1/4, I will take it down the 1/4 to find out what it does.

So the 20B temp sender's range is similar to an '83 guage? That's good to know for when/if I put mine in a 1st gen.
