Hi everetto, I'll be very interested on how your install on KB setup goes.
I'm assuming by now you've reviewed the "install" sheets in the kit. Are they well done?
I'm about to buy the KB kit myself. It's seems like a fairly straight forward install, but appears it will certainly take a few hours, or more.
Good luck!!

Hi Bill - you are correct, the first thing I did was sit down and read everything that came with the kit (the blower drive and power steering spacer installation, and the tune instructions). The instructions are pretty good, and so far I don't really have any unanswered questions. I will be putting on the tune today, and will report back on how that goes. I plan on driving it that way for a week or two just to get to know it, before I remove the blower for the front drive installation. By the way, if you are in the mile high city, then we are at similar altitude, so hopefully my "tune" comprehended that (I made sure to mention my altitude to Kenne Bell). A friend on this and another forum already has his KB kit in place, and he sure likes his, with some great dyno numbers. Will let you know how it goes.Bill Oxley said:

KB Flash Tune is in the House... er, the computer!
Whoooo Hoooooo! The flash tune (that came with the KB HCD kit) is on the car. Only one test drive so far, but I like it. Response, both full throttle and part throttle seems quite a bit better. It rev'd to 6500 "very quickly" I must say. But perhaps the thing I noticed (and liked) the most, is that at the end of the drive with the engine at full temp, while pulling into the shop, I could hear the fans running! This with the temp gauge at 180. Additionally, the temp stayed just below 180 for the entire drive - most of the drive was at speeds above 35, i.e., speeds at which the engine temp is not usually a problem, but we all know that as soon as you hit a light, or idle while pulling into the garage that the temp goes up pretty quickly. Well, the temp did not go up and the fans were on as I pulled into the garage (similar to turning on the AC as you pull in the garage to reduce the temp). In summary, the car ran great, and cooler. I am pretty sure the KB tune provides for more timing than the stock conservative tune - not sure how much they played with A/F ratio, but the car idled great, did not get hot, and no rattle or detonation. I am guessing that even this flash tune is a little conservative so there are no issues. So far so good - don't know if I can wait one or two weeks before pulling the blower off for the drive and pulley install.

Did you notice what the Rev Limiter was set at? I recently drove mine and by accident it went into the 7200 RPM range and backed off right away. I have an SCT tune supplied with the Accufabe installation.
When you get youre KB installed, I'll be interested if there is more of an SC whine?
Cheers!

That's strong, where are you located and what octaine gas? I only made at the rwhp 600hp with the Heffner pulley, tune and acufab. I posted this pull on the whipple thread. I am set up for 91 octaine California koolaid.
I would like to take a look at those graphs again, but I can't find the whipple thread you are referring to.
Where did that thread go?

That's my fault. I meant to delete one post but errantly deleted the whole thread. I can't recover it because it was physically removed from the mySQL db. Ouch.
Here are Bony's graphs:
Before: Heffner 2.7" Pulley/Tune/Accufab exhaust 602rwhp/551rwtq
After: Whipple Blower 750rwhp/678rwtq

I know of at least one GT with a real cool hidden NOS install.....! No kidding !
I was looking at the graph and expecting the low end hp and tq #s of both to be similar and that the Whipple would just keep going. But, at lower rpm the Heffner 2.7 made almost 150 more hp sooner than the Whipple.
I wonder if with the bigger sc, and less sc rotation that boost just takes a little longer to make. I not beinging critical, just analyzing. In fact, becasue the GT is now so traction impared with all the hp it makes, it may be a good thing the hp and tq build at a steady smooth rate. Any thoughts?

Could a smaller pulley be put on the Whipple blower to get power sooner, with a waste gate to release boost at a preset limit say 20 lbs?

Check with Dustin Whipple, but aren't we talking in a 300 rpm window, don't see the reasoning behind your concern.

I have seen the small bottles used on bikes, but I would guess you would only get one or two shots?? Why conceal the laughing gas?
The 2.7 is making more torque earlier, but with the speed the whipple builds power, I don't think any additional torque below 3k rpm is going to become very useful anyways...I think on the tires most people use on the GT, the whipple curve is preferable...
From 3000 to 5000 rpm the 2.7 pulley on the existing sc makes more power than the 3.3 Whipple, I thought it was significant enough to explore, am I missing something?

All what I can say from feel in the seat is an awesome change. It is hard not to bust the rear end loose when starting off. On a hard run when hitting second there is a little fish tail wanting to happen. Lets face it, this is an expensive mod, but worth it... at least so far... :biggrin
Cuda you're reading the graph wrong.
Dark blue is the HP curve of the Whipple(light blue the TQ), Dark Purple is the 2.7 HP curve (light blue the TQ). The power level of the Whipple surpasses the 2.7" at ~3600 rpm. You can follow the appropriate curves by following them to their intersection at 5250 RPMs.
