1996 MX-3 RS... soon to have MY BP! (X to 56k)

[therieldeal]

a 22 may be too small, an MH 23" slick is just about right.

Shades are you going to the MX-west meet in Kelowna this July???

[Shades]

Yeah I'll be coming just for the Saturday... going up to Kamloops on Friday and over to Kelowna on Saturday.

Nope don't have too... they're just a really negative offset.

[smoke187]

They're OG's (Axis wheels)... Racer X 15x8. http://axiswheels.com/wheels.php?id=racer-x

Just so you know that unlike everyone else I love your wheels. They remind me of the four spoke wheels run Chen on a wicked fast MR-2 in USCC 2. Light and strong is what it's all about.

Ooo gee... 21psi of boost! Hitting the track this Friday... weee!

[mx-3_4evr]

Good luck! I say high mid 11s if you know how to launch on slicks without breaking the tranny

[carrotsnax]

out of control mate! That is one fantastic Mx3! excellent work on the porting and manifold. I was in shock when I saw the turbo mani. Hope you pulled off a fast and non transmission exploding pass.

Thanks dude!

Well, my times are still CRAP!... can only pull a 14.5 and the tranny is still holding. Something is wrong...

I checked over the whole car and nothing appears to be out of order... so I went and upped the boost again to 25psi. Yeah I know scary, but after doing some research and looking at the compressor maps from Garrett, this puts me in the middle of the efficiency island. It pulls a lot harder now, and feels a lot more responsive.

I guess the only thing is to take it back to the track...

It seems to lose power at the very top end of things, but this doesn't make sense since it's such a big turbo it should be making gobs of power at the top end... I'm thinking this wastegate is not holding shut long enough, well now it is at this new 25psi setting.

We'll see, maybe one more trip to the track.

Unfortunately the top end loss of power is due to insufficient head flow. All BPs have a strong midrange and weak topend. You'd need some higher lift cams at least.

Haha or just up the PSI so that you can squeak more air in...
