well, at least you know your 944 can tow your truck should the f150 break down..

Tony, Did you ever follow the post by member "Dfastest951' about having custom R & Ps made? He's in Vegas and has the 190+ street car. Might help.

Is that plot at the wheels or the crank? I assume at the crank. Over 300 lb-ft at 2500rpm is very nice. That thing should pull hard out of slow corners.
The two things I like most about tracking my GT3 vs my ex-951 are the better drive out of slow corners in the GT3 (even though peak torque is much lower) and the taller gears and 8200rpm redline allowing me to hold gears much longer. Sounds like you have both those areas covered. |

That is RWHP!

[QUOTE=Duke;10755372]While the V8 powerband is hard to beat, 400 ft lb is much lower than a 3 liter turbo produces.[/QUat theOTE]
But the LSx engine will live longer. And runs on 91 octane pump gas. No matter... If I were to stay with a LSx engine, it would be a much larger engine that will make over 600tq and 650hp at the wheels on 91 pump gas.... From 2500-7000+ rpms We now have plans for a 496cu inch LS7 TonyG TonyG |

A 350 (5.7L) is the same outside dimensionally as a 496 cu in engine. So it's a straight bolt in affair. Plus everything externally bolts straight up. So it's essentially a long block swap. TonyG |

The only Porsche engine that we are considering is the 2014 Porsche Panamera twin turbo V6. It's that or the LSx. It's clear which is more reliable. And it's clear which can make more power over the long race. But the Porsche engine is lighter and can move the CG of the engine back behind the front axle. So it gets the nod for handling. And the Porsche engine is Porsche. That would make the car pure Porsche. Which is a good thing. But when it comes to racing... you just can't beat the compact light weight LSx V8 for performance. $25K can buy you reliable, pump gas, light weight, power like no other... that will do 3-4 seasons without a rebuild. So there it is.... TonyG |
Damn your logic, damn it to hell!!!

It is indeed hard to beat the logic behind the LS-engine. But logic also tells me I should have gotten a 996 Cup instead and have more spare time and more money to spend elsewhere. Damn it, damn that logic to hell!
Side note. Cost and reliability aside, a 3.0l 16v turbo engine is fantastic to drive and beats pretty much any LS engine except a high end worked machine. (Comparing torque at 2500 rpm is just meaningless for a track car.) |

You have no ideal how many friends I have that go through this every year. And... don't forget about the sequential trans. That too gets serviced to a tune of close to $15k every season and a half +/- depending on how you shift. And.... last but not least... racing fuel at $10/gal (vs $4/gal for pump), there's another $4000/year in fuel costs. So say... an additional $40k per year to run the Cup Car over what I've built... which is... btw... why I built my car in the first place :-) Side note. Cost and reliability aside, a 3.0l 16v turbo engine is fantastic to drive and beats pretty much any LS engine except a high end worked machine. (Comparing torque at 2500 rpm is just meaningless for a track car.) If I had a regular H pattern trans and had to shift, they would kill me just in the time it take to shift. Once I put in a 496 LS7 with over 500ft/lbs at 3000rpms... it's gonna be bad news for them when I pull out of the turn at 3000rpms and pull to over 7000rpms w/o shifting. :evilgrin: TonyG |
