Has anyone ever rebuilt their motor and converted to a normally aspirated setup?

[Gulf GT]

Has anyone ever rebuilt their motor (removed blower) and converted to a normally aspirated setup on a modern Ford GT? i.e raised the compression to to 11:1 compression, converted to stacked injection, raised the redline, etc...

Found this post here related to it where Kuttner was going to do over 900HP normally aspirated with an 8 trumpet fuel injection system: http://www.fordgtforum.com/forums/showthread.php?t=7843&highlight=aspirated&page=3

I am kicking around the idea of buying another FGT motor, rebuilding it and switching it out to a normally aspirated race motor.

Gulf...interesting question.

A couple years ago I saw a Ford 5.4 naturally aspirated engine with carbon fiber EFI trumpets at SEMA. It was gorgeous!!!

I took pictures, but unfortunately have misplaced them. I have gone to their website and noticed something interesting that only appears the first time you click on their engines tab. A shadow view comes up of the 5.4 engine with 'prototype' embossed across the picture. You just can't get the image back the again...on the same computer (it must drop a cookie preventing the view).

Nonetheless....it is really intriquing. I just can't bring myself to lose the HP to get the look. But it's hot!!

Will the injection stacks clear the clamshell glass?

He doesn't actually say the engine will produce 900bhp though. I suspect the injectors and trumpets can flow enough air and fuel for 900bhp but whether the engine can actually do that is another matter. It depends how you interpret his post I guess....

Yes.

We figure 650-700HP max on pump gas.

Just thinking about the look and the different feel to the driving. How about 8 orange trumpets to look at through the glass? Also brings the car back closer to its roots. Could even add the “bundle of snakes” exhaust going over the back of the engine area as the current air box will not be needed. I just think it would be cool to have a modern FGT with that nostalgic racy look. Not to mention a much higher revving engine, different power band, and exhaust note. We catch a lot of flack from “other car guys” about having to make our HP with supercharger and not normally aspirated like the original and most all racing regulations. I see no reason why our car can’t beat them at their own game, and at the same time create something really like the old Ford GT using modern components.

I don't even know if this is possible with the GT engine, but I was reading on another site about a guy who took a GM Northstar engine and swapped the cylinder heads side for side so that the intake ports were on the outside of the block and the exhausts were in the "V". That would really look cool with the headers coming out from the top and a set of injector tubes at the sides of the engine.

I much prefer the looks of velocity stacks. You're idea sounds schweeet! I would love to be looking at velocity stacks throughthe back window.

Richard, that's sounds cool too. Didn't Renault do something like that for F1?

Mr. Pockets, the velocity stacks I saw on the Roush engine had a lower rise than the supercharger.

like this one A J FOYT used

I am pretty sure that I could make something like this work.

I know a guy who converted a Nissan Titan motor (with drive by wire throttle control) to an individual throttle body setup. I have no idea what it would cost but I'm pretty positive we could make this work.

Stay with boost! Much more power available and it is orginal. Get a Viper for that. I say don't do it. It is your car so do what you want........thats my 1 cent

 

[RALPHIE]

Isn't the Matech engine naturally aspirated (although a different block as I recall)

 

[Ed Sims]

no blower mod by Huffaker

Ralphie - there is a race car shop, Huffaker Engineering, based out of Sear Point Raceway that has done the conversion. They specialize (their "design focus" is) in the Ford GT & Mustang according to their website. I spoke with them at one of the events at the track. The conversion to no blower is done to meet some race organizations requirements.

I wonder how much weight you could lose by replacing the supercharger and removing the associated cooling systems.

Would you be able to keep your gal running cooler as well?

 

[Ed Sims]

weight with no supercharger

Shadowman?
