233 rwhp dyno sheet
#31
I don't think there is a question. There is nothing to "figure out".
Eric has a well built engine that made a ****-ton of torque and power (for an NA, restricted-build Renesis) using the same sort of tips/tricks that all the GrandAm teams are limited to.
For those of us that had the opportunity to tune those cars, anything over 225 was happy time, but 230+ was payday.

Stock claimed HP was 236 but that was flywheel. 15-17% loss in the drivetrain makes claimed RWHP around 200. Most stock cars dyno around in the 170-185 RWHP.

I'm on the edge of my seat, I'm guessing he won't tell all because it would allow others competing to copy his hard work and remove his edge over the competition? Very impressive numbers.

Let's try this again. The chassis dyno sheet offered in post #1 captured on a dynojet is a non-ported Renesis. Non-turbo and non-supercharged. How did these big numbers occur?
There are several assumptions here that people are throwing around--a bit like those in a Who-Dunnit mystery who talk out loud and people believe them. On the other hand a few of you are stating the right things. Put them in the form of a question and some of you will get there lickity-split. It's the ole' outside the box thing. Try using the Socratic method and you'll colectively figure it out quickly.
The question is this: How did a stock Renesis make this much power?

You have spelled it out in other post like this one. https://www.rx8club.com/showpost.php...3&postcount=71
Baiscly you build a good motor, with new or mostly new parts, balancing the rotating assmebly and the fuel injectors, a few oil and coolant flow tricks to improve longevity, Use a high flow intake, long tube header, tune it for the spec 98 race fuel (Probably the .93 Lambda aka 13.5 AFR). Break the motor in and then make your dyno pulls. Run it in 5th gear to make the most power.

If I shift to 5th gear then I loose on my lap times as the RPM drops to around 6000 and I also loose a bit of momentum so close to a 3rd gear corner. So this is why I keep redlining until I reach a speed of 198kmph in 4th gear.
I believe the extra HP and torque with a SC will allow me to shift to 5th gear and less strain on the mechanical components. This is only a theory and once I have converted only then I will be able to find out the benefits of any on my lap times and how reliable the system will be. I will have to learn to be less aggressive and show more mechanical sympathy.

Edit: I guess the guy up a few posts got it nailed by finding one of your previous posts. twas fun while it lasted

Just for fun - here is Eric's dyno as compared to a relatively strong stock dyno and a Greddy turbo on stock waste-gate with no boost control.

It boggles the mind to think how much research, testing, dyno time, and tuning go into getting that extra TQ and HP.
Makes me very happy to have the numbers I get from my mostly stock NA.
