Is this a stock head and cam setup? Any plans to upgrade heads and cam?

Steve, it is completely stock. It was a brand new crate engine from GM with nothing added. I have no plans to upgrade. It is way too fast already.

315 RWHP in a 2,100 lb car = 10 second 1/4 mile car, if you can get it to hook. SmileWavy

For a few hundred more you could push close to 400 hp! I'd love to see more pics of the setup and install.

I was at 2950lbs. I would be a little slower in the 1/4 mile...

Here is a link to todays Dyno. Nothing too exciting:

Just weighed the car again. The previous weight of 2940 was with the old wing, no AC compressor and no AC condenser on the rear wing. The previous wing was metal with a rubber lip and a different radiator with dual fans.

The weight today is 2920 and I have added the compressor and rear condenser. The rear wing is a Toy-Jet wing with his radiator and setup. The newer wing is fiberglass and the lip is also fiberglass, although it looks like rubber because of the paint. After taking the car to the tuner, lowering the fan on/off temp, changing the fuel mix and timing, I can not get the car to go above 184F. Same time last year, didn't matter if it were cold outside or not. If I brought the rpm's up above 3500, the coolant would get well above 220 after a few miles of driving. We shall see what the summer brings.

So far, I have lived up to what I set out to do. Swap motors but not cut up my car. It is pretty much stock with an obvious LS1 in the rear but everything else remains. AC is working nice. Summer will tell how nice. Getting ready to deal with the heating. A guy down in Oklahoma is building me a heater box/core for the rear, under the rear seat with a Spal fan and ports into the original heater ducts. We shall see how well it works. Getting cold up here in NY.

From looking at that 0-60 video there seems to no need for upgrades. And unless your are planning on towing a trailer that massive torque makes 1st gear in a 915 obsolete!:)

It sure makes 1st gear in this G50 01 obsolete too. Wish I could spring for taller gears and wish I swapped out fifth gear when I put the new motor in. Do you have a trailer hitch? I sure wouldn't mind adding one! I could get rid of my Jetta TDI!

Being both a 911 fan, and a muscle car guy, I have thoroughly enjoyed this thread. Thanks for sharing, I love your car!

yeah you got her running cooler!

Thanks all! She is running! Waiting for heat!

I'm going to ask an honest legitimate question. I think this car is awesome, I have no issue with it. But right now I have a C5 Z06 (That I am selling for a hot rod 3.4 '75). My car is on Coilovers and has Sparco seats and actually weighs only 50 pounds more than your car with 385 to the wheels. A good one can be had for 22 which financially is a better move than an ls1 911. Going back at it would you not rather have the car that was developed and designed to have the ls1/ls6 etc? I'm wagering my Z is probably faster than this car, better around a track and cheaper. Just an honest question and hopefully this didn't come off as a poor taste comment.

^^^Sauce.

Not to be confused with 911SauCy.

Thanks...and, have a great day:)

Sauce, I would rather have the car I have. I didn't buy it originally with the thought of putting in an LS1. My motor ended up having issues that would eventually need a re-build or a new motor. I read about the swaps and moved forward with it. They are just different cars and both are great. Hopefully you can find a 911 with an LS1 that someone would be willing to sell for 22. It would never cross my mind. However, I do see lots of 944 LS1's for sale for less then that. Good luck with your sale.

to add to yans comments...i have two v8 conversions. one is a sbc conversion in a 71 and the other is a 930 with a mast motorsports drive by wire ls7. it never crossed my mind about a z06. for my purposes, i wanted a porsche hotrod with plenty of non-porsche horsepower. i dont have any problems with porsche engines but wanted v8 power and not six cylinders. the 78 930 weighs in at less than 2400 pounds and has 705 crank horsepower. it was not cheap but it was what i wanted to build. and, it was the combination of power, body style, handling that i wanted to drive on the street...

Understandable, makes sense put that way. Enjoy the car! I'd love to ride in one, I'm not looking for an LS powered car though, I love my bette and I'd just keep it if so.

That would be a terrible thing ;)
Lol that car sounds nutty. Videos?

Nice!!! Pics

The car looks good!

Simply amazing. I'm in the process for gathering parts for my LS build at Tarmac-SPL in Farmingdale, NY. I still need a transmission and the mount kit. Any regrets during this build? I may have missed it but do you have an LSD G50? Where in NY are you? I would love to come experience this first hand.

smellslikecurry, I am in the Hudson Valley near New Paltz. Not driving the car in the winter but come spring time... I have the G50 01 but not LSD. I wish I had taller gears. That makes a big difference on cooling and noise. There is no reason not to put very tall gears in the car in my opinion unless you are racing the car - then you need to speak to an expert. I also wish that once everything was running I immediately got the car Dyno Tuned. Would have solved some issues right at the start. Get a G50 or 930 Tranny and put tall gears in it. If money is an issues at least put the tall 5th gear in it. One day I will do the same but don't want to take the motor out again. Hope that helps.

Yan,
I love my car just the way it is which is almost 100% pure Genuine original Porsche, its fairly rare so I am not about to hot rod it. Thats just me with my particular car
However, I pretty much love everything Porsche, including hot rods, modified, conversions etc and I love what you have done.
This site has tons of examples of owners brave enough to make their vision a reality and like you some do it very very well.
As for those that have been harsh with you they are entitled to their opinion but have to say I was impressed how you handled them and kept on going on your way.
By the way I probably wouldn't swap my car for yours but I sure could make room for it in the garage next to mine anytime!
Cheers Mate!

Bill, thanks for the kind words. We all enjoy different things in life or life would be pretty darn boring. Many people modify their cars on Pelican and get help from the entire forum. I have certainly benefited from the forum even if a few have been harsh. The amount of energy and wisdom here is incredible. Dedication of the members speaks for itself.

I installed a taller ring and pinion in my 996 C2S-LS3/480 HP (removed the front wheel diff), at 70 MPH I'm turning 2,200 RPM. The net weight of my car after removing the front diff and installing the LS3 motor is 3,030 lbs. That's net with the fuel removed at 6.5 lbs/gal.

With the taller gear the performance is still there in all gears, (387 ft.lbs. torque) also the engine is a lot quieter at cruise. In fact I get more tire noise than engine noise... Breath taking to drive...

Mitch, sounds incredible! Do you know where your rpm was prior to the change? Did you put in taller gears and taller ring and pinion? Love to see you keep a chart and post it as you visit certain speeds...

And is you hp and torque at the wheel or crank?

Thanks!

So much snow here. Can't wait for spring!

Ring and Pinion Upgrade...
 

Yan,

Here's the speed/RPM chart for the taller ring and pinion. The engine is rated at 480 HP, the car dyno at 391 HP at the rear wheels, and 381 ft.lbs. of torque. Max torque peaked at 4,600 RPM.

Mitch, those are some amazing numbers. Did you ship out your tranny? Very costly I would assume. If I drop my motor again I am sure I will have to follow suit. Can we see some new wide shots of your beast on your build...

I delivered the transaxle to Renegades shop in Las Vegas. It gave me a another opportunity to ask questions and look around. It was expensive and added a lot of cost to the build, however I believe that it's the correct decision for the long haul.

I can leave in 2nd gear now, with the stock Ring and Pinion I don't think you would need lst gear. Guard makes gear sets for the 911, but not for the 996. I've got hundreds of shots of the build, but most are detailed shots.

Took the 89 911 LS1 to Lebanon Valley. The car ran a 12.554 at 112.83 - bone stock 04 LS1.

Very cool Yan2947. Car sounds great too

not for nothing but with more practice (read aggressive) driving she should go into the 11's

I am sure practice makes perfect! I will try next time. Does anyone have a completely stock LS1 with 1/4 mile times less then 12?

great job....... Still waiting on mine to get done...hate body shops.

I am using the Toy Jet system. I really wish a couple of LS guys could let me know what their temps are when at high rpms. Even the guys with tall gears when they drive down the road in a lower gear at 4000 - what are their temps on the LS temp sensor (factory installed)... for front and rear radiators. I have a good sized radiator and by math it should do the cooling. I am not sure that the LS motors were meant for high rpms and therefore the real answer is tall gears or a larger radiator...

Last Wednesday it was 86 degrees outside
3000 RPM for 10 miles Temp of engine coolant reached 208 degrees - MAS temp was 84 degrees
3500 RPM for 10 miles Temp of engine coolant reached 233 degrees - MAS temp was 82 degrees
4000 RPM for 10 miles Temp of engine coolant reached 244 Plus degrees - MAS Temp was 82 degrees - the temps at 4000 would have risen but I wouldn't chance it.

3000 rpm on highway 5th gear around 71 mph
3500 rpm on highway 5th gear around 82 mph
4000 rpm on highway 4th gear around 74 mph

Can anyone else post some results here. Thanks!

Hello,

Have you experimented with different types of thermostats? Maybe the coolant does not "stay" in the radiator long enough to cool off before being sent to the block.

3000 Rpm for those speeds seems too high for such a torque generating engine too.

By the way when you drag raced the car, did you took off in first or the second gear?

Best wishes.

I have removed the thermostat but didn't notice a difference in temps. It is back in the car. Getting a new temp sensor today to see if it could be that. At Lebanon Valley I used second gear for the runs except the last run where I started in 1st. My last run was the best but each run saw an improvement. I think the extra shifting will prove to be slowing the car down. My second gear takes my to about 60 mph while 1st only to about 30 mph.

Yan, could be an air flow problem. At speed you could be creating some dead air space in front or around the radiators. My buddies mustang used to do that. Around town the temps never got over 180* but as soon as he hit the highway they went up. The faster he went the hotter it got.

Yes the engine will produce more heat at higher rpm so that is normal, making sure the coolant slows down enough in the radiator to dissipate heat is very important but so is lots of air flow across the radiators. Can we see some pics of your radiator locations?

ok, i just ran back thru the post looking at the radiator. Looks good to me, I say ring and pinion time. These Ls motors like to idle down the highway. My 85 500 SEC has an LS1 / T56 swap and I can go 80mph at well under 3000rpm

Very sweet MB! Speed isn't the issue. I can replicate the issue at 20 mph in first gear at 4000 rpm. Sensor was just replaced and I will see if issue is still there...

oh ok, very interesting. That changes things. Possibly not enough ignition timing in the light load high rpm bins? That set-up uses a remote water pump right?

Can u take your MB out for a short ride at 4000 rpms for 5 miles low speed and let me know what temp u reach on an obd2 device for the internal ls computer?

Yan

I can try it on the way home this evening
