Floor stands, hydraulic jacks and wood!But my hands hurt.I am getting to old to do this myself.But I am to cheap to have anyone else do it.I have about redone the whole car.Can't wait to take her out.Wish I was in California.

Wow,sweet setup. How much hp are you going to set the stage 3 at? I did notice that the upper brace was not on the kenne bell supercharged gt500 on his web page.I'm hoping that was removed just to take an unosbtructed view of his supercharger.Did you get the polished unit? Anyhow lucky you:) GGBIW

Say goodbye to the strut tower with the KB kit. There's barely enough room as it is and as most will concur, the strut tower on these cars is more for show than for function unless you're autocrossing at 9/10ths. As far as HP. I should be ending in the high 600's if all my moons align correctly!

I can run 91 but as the kit says in the instructions, its not a bad idea to keep a can of N.O.S. octane booster in the trunk just in case you get a bad tank of fuel. I went with the black case 2.8H instead of the polished unit basically because the valve covers and just about everything else in the engine bay is black and it looks more "factory" and less "blingy".

Nice choice. I will be getting the KB also but am gonna wait a while before I do. I dont like the idea of having to cut on my hood to get the 2.8 KB to fit.
By the way did you say what pulley you will be using?

Im using the 3 1/4" pulley to start. With the headers it should put me near the high 600 HP mark. Thanks!

I thought about the Whipple as well, but as far as I know they arent offering a larger throttle body and the big drawback is that it wont fit under the stock hood and I didnt want to replace the entire hood on my car and have to have it repainted and striped.

I was under the impression that the Whipple was a direct bolt on replacement not requiring any major modfications. Thanks for the input as I will research this further.:)

Have you read the the piece on the KB 2.8 being put on the GT500 in the latest issue of 5.0? I think it says you will have to take the hood pad off and do a small amount of cutting on your hood to fit the KB. But they have great results, 810 rwhp and they figure about 1000 hp at the engine ( not flywheel ). KB says the stock headers are so good they dont have to be changed, maybe for weight is all. Good luck with your transplant hope to learn alot thru your experience on with it.
Also there is a nice chart in the 5.0 mag showing hp and torque with stages 1,2,3 and all the pulley combos. I think if you have the 77 throttle boby you will easily get 600 hp without changing headers, since you got the stage 3 you have all the goodies to make it happen.

Was your 3.8 a typo or were you talking about the 2.8 twin screw? I don't mind taking the brace out but don't want to mess with the hood.:confused:

yep typo and i try so not to make those. fixed. But yes it says you have to make a small cut on the hood to fit the 2.8 KB. It also says you have to take off the pad under the hood. I dont know if you have to leave it off or just take it off to make the cut.

Just received a email from Whipple and their twin screw will be out in a couple of months. The reason for the delay is they are attempting to get it under the stock hood. Will keep you posted.

You do need to remove the hood blanket and make a notch in the X brace. I comes with trim material to make it look factory. You can replace the hood blanket if you wish, you just need to make the same notch in the blanket to clear the supercharger case. Im not worried about notching the hood at all. Im didnt buy this car as an investment, I bought it to enjoy it until the next best thing comes out from Ford!

I totally understand. I'm not putting this on my "investment" shelby. I'm going to purchase a second one that I'm going to "hop up" so to speak. I still say the Kenne Bell is tops as it puts cooler air into the engine. No sense in working against basic physics as heat works against efficiancy. My wife has calmed down on me purchasing another gt500 as I told her the one in the car capsule will be an investment for her to deal with later on in life. Her jaw dropped when she saw the bidding on Barret Jackson. How hard is it to remove the hood blanket? Thank you for answering my questions. GGBIW

Removing it is extremely easy. Just a few plastic fasteners. I may put it back or I might just line the underside of the hood with some heat absorbent or reflective material to make sure I dont hurt the stripes or paint. Im not sure yet.

Can't wait till you get it set up. I hope youve done some of the suspension stuff that the other members did to stop the wheel hop. Are you doing an upgrade to the driveshaft to handle all that torque? Kenne Bell twisted a couple of them on his dyno. GGBIW

Yes Ive got the driveshaft as well. Same one that KB is using. The initial ones they broke were the wrong length. The aftermarket GT500 driveshaft is shorter than an aftermarket Mustang GT driveshaft and this wasnt noticed until they had a bind and it broke. Inland Empire Driveline went to KB and took measurements and found out that it was indeed shorter, so they went back and made them a new steel shaft and they havent had a problem since. I got my new shaft from Inland Empire as well so I dont anticipate any issues. Other than that, all Im doing is the LCA's and maybe the pinion angle adjuster.

Hmmm interesting developement. Im glad I waited and didnt order the KB right off. Maybe a price war will get going and maybe Whipple will do something about hood clearance. Whipple is making some big claims about their GT500 blower so I will wait and see how the direct comparisons between the two turn out. I will want to see air temps and parasite drain on the hp with the Whipple.

I wonder if the Whipple will run as cool as the Kenne Bell? I saw a couple posts about engine compartment heat that were troublesome. Anyhow ,that is something I want to avoid if I can. I'm assuming the Kenne Bell Doesn't have this problem. I saw Shelby was developing a cold air system to the front brakes. You need to modify your front grill though Looked good but that wouldn't help in the engine compartment I would think. Cooler air makes more hp as well. Be nice to be able to get 650-700 rwhp without a substantial increase in engine compartment heat. That might be unrealistic though as hp produces heat. :confused: :) GGBIW

ggbiw,

Thanks. I know nothing of superchargers and I'll be the first to admit my ignorance when it comes to anything to do with their make up.

That's why I think it's helpful to try and stay away from acronyns.

I must admit that all of this information sharing is certainly not going to waste.

You guys are providing a very good service, so please carry on.

cgoeschel
03-25-2007, 09:32 PM
Sorry about the acronym. It is in fact the throttle body. The initial ones sent out didnt have a necessary teflon piece on the rod that holds the throttle body butterflys. Consequently it was letting a very minute amount of air past the rod and causing idle issues. Easy fix, just not so easy to find at first. I should have it back by Wednesday and Im spending all day installing the supercharger and waiting for it to show up!

Its not on yet (tomorrow). I expect engine/supercharger temps to be lower than stock. More importantly the IAT (inlet air temp) will be lower.

By design the screw as opposed to roots supercharger will produce less heat with greater efficiency. The key question is cost over HP out put. Pulley idler or heat vs. $$. At some point screw, but for now pulley and idler. Just my opinion.

The limitation is in the smaller pulley with the Eaton. You cant get more than upper 500's with a pulley change on the stock supercharger. Upper 600's to low 800's are available with the screw blower again at lower IAT's than a pullied Eaton (safer) and with that comes less chance of detonation from heat. 100-200 HP is a HUGE difference on a car like this.

You have a good point. I just don't like raising the heat .Thanks for the info on the supercharger efficiency. I believe adding heat works against efficiency.The Kenne Bell , I believe is the best. I don't like taking out the strut brace but will .Evidently Whipple has one also. Maybe you can still have the strut brace with Whipple.cgoeshel will have one of the baddest Gt500's in our Forum.

Yeah. I figured it would be pretty easy too. Changing a supercharger for a supercharger should be no problem. I wish I knew what to do first so I could start on it though. I have done centrifugal kits which are a lot more involved. Especially the intercooled procharger kit. Not hard to do, just time consuming, and I wanted to make some improvements along the way. I don't expect to change anything on the KB Kit.
