Look at those dyno graphs!!!

Great jon Brian!

*edit*

they use the 5th gen version of the mp112 head unit. Although the price for the FI setup is pretty "heavy".

If you can figure out the belt routing, and if there's enough metal for the bolt holes, you should be able to get it to work. just cap the unused radiator housing, and you'd have a distributor hole to boot.

Looks like it will need a bubble like the later generation Corvettes

Helps to visualize it a little better.
Wouldn’t take much to cover it?

Looks interesting; however, for $7,700 it would have to bolt onto a LTX and offer MORE power...IE that crank horsepower and torque would have to be Wheel horsepower.

Brian- you do a GREAT job with rendoring stuff. Are you in some kind of drafting as a profession? CAD?

the engine can also be LOWERED! Think about a simple engine mount that will lower it an inch... you "might" just get away with it in that respect.

That's PERFECT! If you're gonna have a blower, the drive pulley HAS to stick out of the hood

That would be interesting. Does such a thing exist or have to be fabricated?

Fabricated..the mounts would be simple, however, look at where the oil pan is at now....


Do you really want your oil pan, and exhaust hanging a couple of inches father below the car than they do now.
To get a couple of inches of drop, you'll need an oil pan mod... on the LT1s the damper is already pretty close to the front cross member.....(smaller damper) or move engine a little to the rear?) Exhaust would be a problem on the verts since it is already close to the x brace.

Caveat: I'm not saying it can't be done, just that it opens up a different set of problems. Probably be cheaper to buy the new hood.

Look at post #6 of this thread for possibly a hood solution:

http://forums.corvetteforum.com/c4-f...-out-here.html

I love the idea of that set up on an L98 based car.

That would actually be like my dream C4. I would do a 355 with nice parts in the bottom end... Nothing crazy, just some forged stuff. It's easy with the 355, lots of parts out there, easy to keep the wrist pin out of the ring pack on the 355, etc... Some budget aluminum heads and a small cam. Not the stock tiny cam, but something along the lines of the Hotcam.

Pulley down the blower until you overcome the intercoolers ability to cool the charge, then go up one pulley size.

I bet you'd come dang close to 500 RWHP with that set up, and it would drive really well. If the intercooler was up to the task, you'd have the ultimate C4. Go to the drag strip Friday night, hit the Auto X on Saturday, cruise up to VIR or Willow Springs and road race on Sunday, and finish out the weekend by taking your old lady to dinner. It would be so stockishly docile that your old lady could drive it home from dinner.

That's the ultimate C4, IMO. Heck, maybe even the ultimate Corvette for those of us who prefer the C4 to the newer generations.

Since you built a nice bottom end, one capable of more than 500 RWHP, you could even put a shot of dope on the car and really lay the smack down when you wanted to. 600 or 700 RWHP wouldn't be out of the question on spray, and again it would be so docile...

I would bet you could build that car for 15K. 7K for the blower, 5K for the motor build, and 3K in other ancillaries. God damn that sounds bad ***. Even if you had to bump the build to 20K, it would still be incredible. You be able to out accelerate any stock vehicle on the road, and sport bikes might have something to think about when they rolled up alongside some old C4...

My car makes ~415 RWHP and a tick over 600 on the jug (and drives almost stock thanks to an amazing chip tuner) but I think I would trade it for that build.

Mike- i was thinking more like an inch "at most". not something extreme, because I too thought about the oil pan and header clearance issues.

The smaller Damper would interupt the pulley ratio (i.e. reduce boost).

I love the idea of a positive displacement supercharger, but for $7,700 and the cost of a long-block ($5,000) and your estimate of $3,000 (misc.), you're in pretty deep for "only" 500rwhp.

Here is an alternative idea (sticking with the supercharger idea)

Brian mentioned that this kit has the intercooler intigrated into the lower intake manifold (pretty obvious when you notice the heat exchanger and reservior for the coolant, lol). I would ditch the combination and go with a lower profile lower intake manifold. The difference would allow the c4 owner to "possibly" run without the hood modification. Instead of a convensional intercooler, you can just run the meth injection.


Here is a guy clearing the f-body hood with the Lt-x
http://www.corneltechweb.com/superchargerweb.htm

After all, an aftermarket hood runs ~ $2,000?
