I have two 1600cc secondaries and two 950cc primaries. Aeromotive A1000 pump, Aeromotive FPR, -10 feed line and -8 return line.

I think duty cycle was around 85% but not certain. Base fuel pressure of 50-55psi.

nice to see some more T51 numbers...hopefully i'll get mine on the dyno this Spring...and see what she can do :D

HI! LUPE you sure have become popular, SAY HI to Steve, from the old guy in Daytona.

ronbros3 02-06-06 06:22 PM

you are right on about an automatic trans, sure would make things simpler trying to put that much down, and rotarys are good about not to much torque early in the rpm range, so as not to shock the drive line and break driveline parts. here is one for you , I will race you from 50mph to 130 mph on a 5th gear roll with my almost stock FC. gives you somthing to think about . RON always having FUN.

Eric: man our cars are very similar in mods. I haven't weighed mine in a while but the last time i did i thought it was stupid light at 23xx.....guess i was wrong. That IRS swap must've been worth it's weight in gold;) I did add fiberglass fenders and i cut most of the rear away and put fiberglass overfenders on so it might be even lighter now hopefully. That way i can ballast the car however it needs to be depending on where i'm racing.

I also tried to fit a big turbo.....GT4788. NOT!! It looked absolutely retarded in the engine bay. Like you said with that 88 you tried to fit.....it would've been up between the radiator and engine. Not the best looking or functioning of systems.

been trying to get the videos up..... but no luck. Will try again tommorow. I'm too stupid to figure this out.

KaoticFdR1 02-06-06 11:07 PM

I have faith in you gorilla ;-)

Nice results.

Did Steve build and port this engine too?

I threw my clunker motor together :rlaugh:

Going back a bit in the thread but I can answer a couple of questions in case anyone is still interested...

"Flywheel Power" is calculated horsepower times a manual "correction factor" for people who want that. Our correction factor was 1.00 (no correction). Every Dynapack screen will show this correction factor. On these sheets, compare Power to PowerFly in the top right, you'll see they are the same. On other formats you will see a field labelled "TCF", and that is the manually entered multiplier. If you ever see a Dynapack sheet with TCF other than 1.00 you are being bamboozled.

The only correction being applied to the calculated horsepower is SAE correction, shown as PCRatio in the data box. A PCRatio between .95 and 1.05 means the result is a good solid number. Things get a little iffy outside that range. That applies to all dynos, not just Dynapack, as the SAE correction formula is not perfect.

It also says "Flywheel Torque" but that is a misnomer, confusion between New Zealand and American sensibilities. It really means "wheel torque divided by gear ratio". Eric actually put 2060 lb/ft of torque to the dyno in 4th gear. Now that's a big number. :D

And his car was weighed on a set of freshly calibrated Intercomp digital scales. They are dead on accurate and I supervised the weighing. No BS anywhere in this thread.

good info, thanks :).

Lupe what happened to the others guys that got tuned, inc the mr2 etc let us know results please.

Yellow MR2 started out at 270whp at 19psi. Steve got 300whp at the same boost. His original tune was already good but of course, Kan tuned it better.

Gray MR2 was having boost issues and had to tune on the street to 18psi, Steve thought his car was around 350whp.

IS300 w/turbo came in and didn't run. Steve got around 340whp at 7psi. They didn't have a boost controller so Steve couldn't turn the boost up. The owner was a 80 year old man. I think Steve scared the crap out of him on the test drive :lol2:

This tuning trip had major flaws...... None of our cars were ready to be tuned. We all had mechanical problems so it made tuning take 3X longer. Steve did an awesome job for what he had to work with :lol2:

We appreciate how patient you were with us. It was really nice of you to let us have total access to your all your tools and high dollar equipment.

We appreciate your hospitality.

pluto 02-07-06 12:49 PM

Hey Steven,
It was nice meeting you and your help in providing your time and space for this tuning session. I know that everyone there were very appreciated for the time you spent with us and allowing us stay there as long as needed to get the work done in a timely manner.

I'm sure that I'll revisit your place next time I go back to St. Louis again.

Steve

Incredible Eric, congrats! I sure wanted to make it over there this weekend, but had to many other obligations with family. At least I know with Steve Burkett being in charge the numbers are 100% legit ... and nice work Kan!

Agreed.

Lupe,

When do you plan on running it down the strip?
