I read this whole thing and saw no dyno numbers.

Wooooooooooooooooo.

Jeepers already...272/?

Heaven forbid marines and unicorns visit this page before numbers are posted.

over 9000

Maybe not however it will make a difference in the hp esp if you change the injectors and pulley down which in return would gain back whatever tq lost by adding headers still money well spent. I know you've built and had faster cars which still confuses me even more why you refuse to do the simple things to make the most from that xpz cam..........

Ohh and post the numbers it made already!

Headers won't make anymore power either.

Anyways first pull with the stock airbox:

264hp and 275ish tq

Pulled that off, and stuck a filter on the MAF for the second pull:

266hp and 278tq

It was still running pretty rich, but almost a dead even afr across the board, so I changed my base PE table from 11.1 to 11.3. And, for whatever reason, it went ran richer. Most of the pull was ~10.9afr.

259hp and I don't remember the tq.

I told myself that I would be happy with 260whp before I went in. This is one of those dyno's that break hearts, so I was pretty happy with what I made. It's pretty common for most people to lose 15-20% on this dyno from the dynojet that's in town.

My injectors are at 100% duty cycle at 5100 RPM's, so my next mod will be some bigger ones. I may try to get it to the track first, but I'm sure with that high of a DC, I'm losing a decent amount of power in the upper RPM's.

To what degree are the heads ported?
How many #'s are you seeing, like 3-4?

I'll say..

254whp/313wtq

I spent about 30 hours porting and polishing the heads for it. I have some pictures posted in a thread I started on TCG.

And, I don't understand your other question.

Uhhhh...what?

Boost. Pounds. PSI.
I'm trying to picture how well your heads flow considering your cam profile and minimal s/c output.

Ah, ok. I guess I'm not really sure. Back in December, I was showing about 6psi iirc. So, maybe 5???? I haven't scanned boost for awhile.

(yes I get it that car has way better heads is intercooled and on a way smaller pulley that's not my point)

given the info on the cam and staggered pushrod length for intake and exhaust. I can understand the engine hp and tq numbers climb almost parallel to each other. Which mirrors your hp and tq numbers.

All of this still makes me believe headers injectors and a smaller pulley with another tune obviously would make this car an entirely different animal!

Btw please explain how injectors and a smaller pulley would help when its still being choked out? Can't cram more air in if you can't get it out.......

Because, exhaust manifolds are not a restriction. The car is having no trouble getting the air out. I don't understand where you are getting this idea.

No way you will see 400whp without an IC. I'm guessing with some race gas, pulley, and injectors, the car would maybe make 350.
