Came back from seeing the car this morning. It's up and running! Only has 50 miles of break in done, all on the dyno. Rev limited to 5000 rpm right now, no timing in the maps and it's already +40 ft lb and +40rwhp over what it was doing before.

So right now it's making 400ft lbs of torque! With more break in miles and proper tuning with timing added as well as revving out to my 7000rpm redline it sure looks like somewhere in the mid 400's for whp is realistic.

Shop is going to replace the front wheel bearings, install the missing instrument cluster lights and I'll hopefully get the car back tomorrow or Tuesday.

Then it's time to put the 500 break in miles on it, then bring it back for final tuning.

Very excited!!!

fantastic to hear the great news !!!

being patient with the break-in and tuning, and less in a hurry to get on the track is a good thing...



btw

I got a XSChop 944/68/v8 ps pump bracket if anyone wants to run the Porsche pump on their setup.

I recently had my LS1 rebuilt from top to bottom at Turn Key engines (Oceanside CA) for $2350.00 They have an incredible shop and they did a great job. Balanced the engine new valves, lifters, rings etc. and it runs incredibly smooth. I originally went to buy a long block and was surprised when Paul told me they could save me money by rebuilding mine. Everything turned out great. This car has the best throttle response of any car I have ever driven. I am now working on the suspension and plan on being able to compete against the GT3's at the autox in San Diego. Car accelerates so hard that the rear squats and I get to much push exiting corners. I am now upping the spring rates to solve this problem.

$2350 for a complete rebuild!!! Labor and materials?

Yup it will be the SW20 pump. The steering wheel is what factory systems use, if you are turning the wheel but not moving, you still need the pump to be working, so vehicle speed alone doesnt help. But fine for a mostly track car as you dont need to park too often

Yes $2350.00. It was a surprise to me too.

The primary purpose of that is to raise engine rpm due to the electrical load on the alternator when the steering wheel is turned at idle. This is due to the fact that the MR2 has a tiny engine and any additional load on it at idle will cause the engine rpm to drop considerably. With the V8... its not even noticed.

The VSS sensor input on the other hand, dials back the pump rpm as speed increases to vary the steering assist level. With the MR2 this is a good thing since the car is so light and the fact that there is no engine in the front and thus no real weight on the front tires.

Neither of which is needed on a V8 944 street or track.

Nice build Doc and great numbers to boot.

Hopefully get the car back tomorrow. I'm curious to see if the Boxster ABS is working and how the motor feels, even on the base tune/no timing. Once I get 500 miles on it we'll do a complete tune out to 7000 rpm and see what it makes.

TonyG

500 miles!??

How do you put 500 miles on a track car?

After a few heat cycles and tuning at the things are run at 100%.

Easy, the car is licensed for street use. It's a time trial car, so it has a stereo, A/C, stock power windows, cruise control, door panels, etc. I've removed some of the sound deadening underneath the front seats, deleted the rear seats and have Recaro fixed back seats, rollbar/harnesses, but still have the factory 3 point seat belts.

So I'll drive it around the next few weeks and get the requisite mileage on the motor...

Do you run mineral oil (pentosin) or atf? I know the cup cars are factory filled with pentosin, curious if the mr2 pump is compatible.

DOC, did the RH/ Ron Davis rad solve the cooling issues?

docwyte

It helped, but mostly it's just a question of getting used to the temps it's making up here. The CMC Camaros are seeing the exact same temps as me, so it's the environment (hot, high altitude) much more so than the car or radiator.

I need it on my track car, just because I drive it to the track (we can drive track cars on the road with an authority card here). And have to park it in the garage etc. So helps to have some PS when stationary...
