Why port the head that much? No reason really. Trying something "new" for the most part. The fact that it holds power for so long I kind of like though! Maybe we'll do some tests in the future on our staged heads and see what the difference is. Until then, I think our goal is just going to be getting it to hook on the dyno, making a clean pull up to 8500, and then getting it to hook on the track, and hope for a 9.xx @ 14x.

No offense, but hooking on the dyno?? Who gives a shit how it hooks on the rollers. You have been hanging out on TCS too long.:)

Lets get that tq number up a bit and make it to a track outing. Lets see some real track numbers, if I wanted to see some bench racing I would look elsewhere.

Dont get me wrong, you need to figure out your 'stages' but why post about them when you havent figured them out yet?


Again, nice car and great numbers, lets just not jump the gun here.

Kinda like how 550cc injs are 22% bigger than 450cc injs, but 450cc injs are 19% smaller than 550cc.

Umm, what? Can you give a link to an explanation or send me a PM with that info or something? I fail to see how standing on the top of a building would give you a different height to the ground than if you were on the ground looking up, metaphorically speaking. Math isn't kind to metaphores though.

450cc x 122% = 550cc
550cc / 119% = 450cc

In simple terms, 3 is 50% bigger than 2, but 2 is 33% less than 3.

It needs to hook on the rollers to get it to a good state of tune! We currently have no idea what the car is doing above 7700RPM as far as Air/Fuels are concerned.

Part of me likes the torque where it is at. It might actually hold up where it is at. Stock Evo3 transmission, stock axles, stock transfer case, and a twin disc might be able to do a clean pass.

I'm not really bench racing. I said we are hoping for, not we are going to run. The track is definitely in the near future, but we NEED a roll cage before we even street tune it. The car has NO seatbelts. I'll be damned if any of us are going to go out in a 700whp car and do street pulls without seat belts. The car was reckless enough at 530whp, I can't image 700plus.


As for you fattyboombatty, Shane is correct. Its all in how you look at it. Punch in the numbers. It's all about scaling.

450*1.22(22percent) = 550
550*.81(19percent) = 450

*Edit* I got super out holeshotted!

Alli can i say is, that i am really upset that i didn't get to see this car in person. But from what i was told, it sounds like an awesome car for MAP to have their name on. Good job guys.

I would think the clutch slip is a big issue also.

See that's the weird thing, we had no slippage on our dyno for the most part and it is a 4000+ lb roller. I also don't think that with such a light car that slipping will be an issue on the street...

A new twin disk on street tires, I doubt it.

Well the clutch was slipping bad on the dyno, so getting an accurate tune will be hard.

4000 lbs is light?
