Ihave updated my site with dyno and video of my LT1 M112 Project!
Enjoy!

That's really cool. Nice numbers especially on a mustang dyno. I love the street vid and the whine.

 

That is sweet, I just wish it had an intercooler and it used a TVS 2.3L!!!

 

I am currently making Whipple 140ax setup which is also 2.3 liters and capable of 1274 cfm and up to 30 psi and is more efficient than the 2.3 TVS. Are you interested now?

nice... what manifold did you start with?

 

+1
he may have used a gmpp carburated intake manifold for lt1/4 engines?

 

Cool project!

Good luck getting 30psi from a 2.3L Whipple.

 

Nice numbers, project and your site was cool too.

The manifold is made from 6061-T6 aluminum plate and tubing, completely custom fab. I did not modify any other manifold to start with.

 

I realize 30 psi is not happening with this engine combination. There is a pressure vs cfm curve for every supercharger. These relationships are inversely related to each other. The higher the cfm the lower the psi and or the higher the psi= lower cfm (backpressure). E.g. supercharger spinning blowing into free air (not mounted on engine) would yield high cfm and very low psi. E.g. #2 supercharger bolted to a flat plate with no outlet spinning will make a static pressure of 30+ psi but no cfm flow. Max psi gives us an efficiency and static comparison to other superchargers so we can see that when we are not using the full flow of the supercharger (e.g. installed on a small displacement engine) what kind of boost levels we will achieve. I my case, my engine will flow approx 800cfm @7 psi and when I try to approach the 1200+ cfm with the Whipple I will probably see a gain to about 16-18 psi in theory. Of course who knows until I try? If I want more boost then I would have to increase cfm by going to a larger supercharger. Now in theory it takes about 150 cfm to make 100 fwhp. 1200 cfm/150cfm x 100 = 800hp. Don't forget about parasitic loads (supercharger uses 40hp) etc. If I can get 1200 cfm pushed through my LT1 then in theory I can make 800 fwhp - ~40hp and subtract drive train losses of 15% = 646 rwhp. This is a crude estimation but not to far from reality. If you want to test this out then lets use my current setup which makes 420 rwhp divided by .85 to give us 494 fwhp + 40hp for supercharger = 534 hp generated. Divide that by 100 = 5.34 X 150 = 800cfm. This is very close to the measured flow on my setup. Since my goal is 600+ rwhp for my next Whipple project I am certain that it will produce the results if am looking for. I don't mean to ramble but I do want to clarify my thinking behind these projects, and as you can see I think too much, and talk ever more!

Nice car nice numbers

 

very nice
im ready to put one on my LT1

 

That is freaking awesome. How much would a setup like the one you already built cost?

 

Cool!

A friend of mine did this several years ago on his Formula.

 

That's a fantastic result from the M112. Nice work, thanks for giving the LT1 some love. What other info and pics can you share from the new project with the Whipple ?

Props for following through to a finished product for the LTx cars

You should definitely look into marketing the base components for a DIY LTx setup. There would be plenty of people that would be interested in this setup.

 

I am still in the early stages of design with the Whipple. I am designing an intake elbow to resemble the Mustang Gt kit with the throttle body facing forward over the drivers valve cover to enabling the use of the original throttle cables. The trick is to make it a bolt on with no changes made to the original parts. I have a good preliminary design, however you will have to wait to see. I learned a lot with the M112 setup and now its time to apply those things to the new design. I'll keep you posted!
I will definitely produce some more when I'm confident with the design.

 

Great news, keep us updated....

 

Any new updates? I really like your set up great job on all the custom fabricating. Id love to have that whine coming from under the hood of my Z.

 

At what PR is the Whipple 140ax more efficient than the TVS 2300? The TVS 2300 is capable of supporting more HP than the equivalently sized Whipple. The TVS 2300 is capable of flowing:
1420cfm @ 21psig
1470cfm @15 psig
1525cfm @ 6 psig.


I have yet to see a compressor map on any Whipple. If someone can provide one I'd love to see how the two blowers (excuse me...the blower and the compressor) stack up against one another.

 

Looks like some nice # for the set up. nice car also....
