Ye Gods Justin...what torque. Is that stratospheric torque/horsepower ratio unique to turbos in general? I've seen torque numbers from you guys 50'ish higher than h.p. with superchargers, but nothing close to this pickup in the 600 rwhp range.

When can I get one?

[toofart 148]

I swear you guys have the weirdest torque numbers... But at 6.5 psi that is massive horsepower.

Thats gonna be a whole new driving experiment... I mean 'experience'...

Good stuff.

Yeah, where do I order? Heh

Good stuff!

The numbers look good, but I'm going to be honest in saying that I think those HP and torque curves aren't much to be excited about.

[U.F.O. 8]

Just curious Shark. What is it about the curves that doesn't excite you?

[Jay6spdRT 46]

Yeah, compare it to Jim, Alan's and Mike's numbers on the dyno

Also, I note that twin turbo has 60-70 ft lbs MORE rear wheel torque than the new supercharged Mustang GT500, which is the new benchmark against which performance cars are now measured, and that's on a very conservative boost level too.

[U.F.O. 8]

Exactly. These turbo numbers are better than anything produced yet on a factory 392 that was PCM swapped and supercharged. They look bad assed to me and remember this car is still running Mexican, cast internals.

notice the power band?

[U.F.O. 8]

You mean the h.p.'s early peak at 4,500?

U.F.O.

[sharkcohen 60]

Horsepower is flat after 4500. Torque falls off just after 4000. I like a flat torque curve, myself.

[U.F.O. 8]

Here's my dyno. Torque falling after 4,000 is typical for hemi's. Notsure's looks the same. The h.p. curve continuing with a positive slope till almost 6,000 is where the supercharger has an advantage...at least in this case.

U.F.O.

Torque is always going to fall if you have a higher tq number than hp.

[Jay6spdRT 46]

Stock GT500 tests at 595 hp and 603 ft lbs - holy shit, that 392 has the same hp, and 88 ft lbs MORE torque than the Shelby.

With stock internals, that is DAMN impressive. Just shows you what Dodge could do with this engine if they were motivated to do so.

Justin. you're getting my car back on July 14th.
