Renn 951

After almost 12 years of ownership, it's time to put my 951 on the market. While going thru engine rebuild pains two years ago, I picked up a modded 996tt that has become my DE car, and I just don't have the time or opportunity to drive the 951 much anymore, so I'm ready to sell it and let someone else enjoy the investment I put into it.

The engine was dry sleeved and rebuilt 3 years and 3000 miles ago, but after we discovered #1 cylinder sleeve was dropping we swapped out the old block with a known good one last year using Darton MID wet sleeves instead. The engine work was done by Ivan at IMA Motorsport. On his engine dyno it pulled 420 hp and 400 lb-ft on 1 bar of boost, and 460 hp/430 lb-ft at 1.3 bar. $10,900 or best reasonable offer; specs and photos below.

Nice car. GLWS. Are the power numbers at the wheel or the crank? Do you have a dyno sheet you can post?

Renn 951

Thanks Shawn! Dyno numbers are at the crank; Ivan used his engine dyno to set the initial tune of the engine. I have pics of the dyno computer screen that Ivan took during the runs; IIRC, his printer was down at the time. Green line is torque, white line is HP, blue line is boost, and red line is AFR. The 1 bar run is the first one below, and the 1.3 bar run is shown next. IIRC, pressure is shown in Pascals (absolute pressure) so 200 pascals = 1 bar above atmospheric pressure.

Ivan is an authorized MOTEC dealer with a lot of experience setting up ECU maps for 951's. After he set up the initial tune on the dyno, he spent a lot of time fine tuning it on the street for overall day to day drivability. He had installed the MOTEC system previously, but after we did all the other performance upgrades during the rebuild he made the appropriate adjustments to the ECU maps to optimize the performance. No doubt it could be tuned more aggressively, but I wanted to keep it fairly conservative for reliability.

Renn 951 - Looks like a very well setup car with a balanced list of quality mods. Best of luck.

I've run with John on the track for years and I can attest the car is freakin fast and well setup. I have to use my superior driving talent to keep up. ;-)

Good luck with the sale, John, but we'll be sad to see you leave the 951 fold...

Renn 951

Thanks Justin! The car was a long-term project, and the goal always was to keep all the systems in balance. Suspension, safety and brakes were all done before going after bigger HP.

Many thanks Jerome! I'm not sure if you ever got a chance to chase my 951 after the BIG power boost (think you were mostly racing and not doing DE's at that time) but there is no doubt that you have the superior driving talent!

It will be sad to leave the 951 fold after all these years, but at least the "Renn 951" stays with me forever on Rennlist!

Does the car pass smog tests? I live in NC. If it pass VA I should be good.

Renn 951

Yes, last VA smog test passed in March 2012. I don't believe VA requires any future smog tests since the car is 25 years old now; not sure what the rules are in NC on that.

BUMP for new price: $10,900 or best reasonable offer.

Could the A/C be re-installed? How smooth is it without the balance shafts? I have heard that you wouldn't want to run on the street with that kind of setup?

Renn 951

Yes, it's a GREAT deal at this price! I'm motivated to sell, so I'm not looking to hang on to every last dollar.

A/C system has not been removed, but it did stop working back in June. Might just need a recharge, or it could be the compressor has failed at this point. I didn't see any point in fixing it if the next owner might want to remove it all together.

With the light weight pistons and rods the engine is not rough like it would be if the balance shaft is deleted from a stock engine. No problem at all running it on the street like this.

henrys01

Wow what a steal. Why cant you be closer to me??

mr965

Shipping is prob around 1k bucks? still a good deal!
