It's almost "showtime"!

[Paul Workman]

I'm hoping to expand the ranks of the "FBI" (Fast Boyz of Illinoiz) soon by completing the porting project this w/e and put 'er back together.

A new Marc H chip, tuned for an additional 50+ hp, NO secondary throttle plates or the stuff to run 'em, 36mm tapered waaaay down the throat of the heads

This is my first porting job of this magnitude. Gotta tell ya...I approach "the moment of truth" with a good deal of anxiety. Will the dreaded "SES" light come on...or not?

Drum-roll later this w/e. Once past the start-up, then on to install the headers and new exhaust just waiting patiently! (Can ya tell I'm gettin excited?? WooHoo!)

Paul good luck with the grand opening!

May all your DIC lights come on and go out promptly, except for the FULL POWER one!

Hey Paul, can you post some pics of your finished porting work?
And good luck with the reassembly and start up.

Yes on the pix (later). To those like Pete and Jeffvette, et al, I know I must sound pretty juvenile - to them "not a big deal". I guess it's kinda like sex for the first time...I can't wait, but have...worries about how well it will go! Those that pay someone else to do the porting...would just not understand; kinda like reading about it opposed to being there, I recon. No matter what, I'm having fun!

More later...

Marc's chip gives an extra 50hp?

Yes, but only IN CONJUNCTION with top-end porting and LT headers and low impedance exhaust. As always, air fuel and spark (timing) are the key to hp. Without moving the air (in and then out) there is only so much a "chip" can do on an engine that is already of the "high performance" variety to begin with.

What this particular chip is supposed to do is:

1. Increase timing a bit - requiring 93 octane "forever"
2. Anti-backfire for headers
3. Bring on the fans (x2) at around 190ºF
4. Set to operate the secondaries above 1% throttle (secondaries on allatime!)
5. Add fuel to accommodate the added in/out flow
6. Modify the knock retard program
7. Reduce that factory 2000 rpm idle habit our 90 LT5s come with
8. Optimize performance to peak at higher (than 160ºF) operating temperatures.

Looking forward to all these features!

WOW i gotta get me one of those 50 hp chips.lol

I think you mean 50 hp gain with all your mods.

Paul i would love to be there when you start her and first drive just to see the look on your face,ask your wife to be ready with camera.

After header/exhaust you should be around 400rwhp can you say 11's

Yep...Zackly what I meant: 50 WITH all the porting/exhaust mods.

Thats what I thought - otherwise I was going update my chip again
You won't believe the difference in the car!

Elevens? Are the heads ported aswell?
