LS-1 Porsche 944 Racecar - Fired up and running (w/ pics)
Well, we had our inaugural weekend at the Las Vegas Motorspeedway a week and a half ago, and it was simply awesome to drive. I've fallen in love with the ls-1 with it's light weight combined with sweet power...not to mention that the sound rings sweetly in my head hours after getting out of the car.
Check out this link for more info on the project:

My buddy is doing the editting on some video we took, which should be up on the site in a few more days.
Ultimately we want to combine the proven power and reliability of the Chevy ls-1 with the proven handling and performance of the Porsche 944 into a highly competetive Enduro Racecar. The Testimonial on the site gives my first impressions.
Thanks Renegade Hybrids for building me such and awesome car!!

The 924, 944 and 968 use a rear mounted transaxle, so there is no room in the tunnel for a T56.
It will be interesting to see how the transaxles hold up to the extra power.

Mmm...transaxle...I wish my RX7 had one to improve the already good weight distribution.
I guess you could swap in a C5 Corvette transaxle to the 944 if it isn't holding up, but for a road racer only I bet the stock setup does fine.

The weight balance is awesome with the light weight ls-1 and originally sweet 944 balance. With a half tank of gas (10gallons/70lbs) the car weighed in at 2563, which would bring its current dry weight (no gas) to about 2493.
With the half tank of gas, and me out of the car the balance is:
front: 49.5%
rear: 50.5%
You can't ask for much better than that on a road racer. Once we go for all lexan windows, fiberglass body panels and other weight savers, plus add the rest of the cage, our weight should be down to about 2350lbs. The power to weight ratio makes this thing a real blast to drive.
Once we get the race suspension on there, and dial in the chassis, we'll run the **** out of the car and see just what breaks...strengthen that weak area, then look into adding power. The power will likely come in a built ls2 or maybe we'll be patient for an ls7...we'll see.

that sounds about right, its right on par with a 1989-1991 rx7 of the same era and similar design.
wow, in race trim that 944 is light! and what awesome balance front to rear... good work, its nice to see something like that using an LS1.

Attached are some cool before and after pics, a top shot, plus a bottom shot showing the custom oil pan to allow for the fit with a stock hood.

Those 3rd gen rx-7 ls1's look mighty sweet to me. It seems like a great match, as I seem to have heard they had a lot of reliability problems, which the ls-1 could solve. I always liked their lines.

Wow, that is a tight fit. It is great that it worked out.
Less than 2400 pounds is pretty impressive.
Are parts for 944s expensive or cheaper than what we be expected because 944s are front engined and many were made?
thanks
Ben

The incredibly low cost of a donor car with the idea that the turbo tranny could handle the stock ls1 power were certianly some of my driving factors (no pun intended :-) ) in doing this.
We will just have to see what needs to be done later on when we go for a built LS2 or LS7 in there!

BigKat -
yes I also heard that there's a wide-body LS1 944 racecar in Florida, with I believe, a mild cam and heads, full race suspension and wide rubber, that was within 2 seconds a lap, of a factory 911 RS racecar with a pro driver. I figure that the Porsche Factory 911 RSR racecars are our rabbit to catch on the track. We'll see...

Curious about that oilpan - steel, alum? Heavy guage?
That radiator mounted down low like that looks freaky. Is that how it looks stock, or was that done purely to allow for the air intake on the LS1?
Nice car. Very cool that there is a kit. Only downside I can see of developments like this: demand and therefore price for LS1 donor motors is gonna go up....(I have the sickness where I envision each and every car I see with an LS1 transplanted into it )

Don't the Egan brothers from Birmingham/Atlanta have some 944 LS1 cars in the works. I know that the 944 LT1 cars they had were top notch and suspect that if they do a LSxx car that it will be the same.
I'm just finishing my Porsche LS1 mid engine 914 now and hope to have it going in a month or so.

As far as I know, the radiator is in its stock location, but it looks a bit strange because the nose of the car is off.
I don't know about the oilpan construction, but I do know that they had it custom made with internal baffles to help prevent oil starvation in hard cornering. I'll see if I can find out more from Renegade.

I must say that I'll be a bit jealous of the final weight of your ls1 914, as it'll be a good bit less than mine. What do you expect it to weigh in at?
