Nope. Launched in 1st.
But I did lower the boost down to 6psi during the launch in 1st gear then switched to 10psi for all other gears. Really easy to do with the Greddy E-01 remote switching button on the steering wheel.
Launch rpm was around 6.5krpm to 7krpms.

Guys, 30 series tires and stiffer suspension are what ruined this car's launch times. Also, a 1.5 inch suspension drop likely adds negative camber which also really increases wheelspin. I found this out setting up my autocross car. I think that the PTP PR person really blew this one. If they had left the test car's suspension stock they would have much better 1/4 mile times in a national magazine.

Or they could just buy some 17" lightweight wheels with 275/40 drag radial tires. I know "somebody" selling this exact setup.

maybe they would, but the car would look like *** lol ( I know i know, form over function but still, nothing saddens me more than an arseload of performance goodies and no suspension, maybe they should have just tweaked the existing setup a notch or two)

When they got the call from car and driver they did not have a lot of time to finish everything. They planned on fine tunning the suspension setup but only had enough time to wrap up the details of the turbo kit and water injection before they had to take it up to Michigan.

Give me a break... They announced the damn thing in 2004, you'd think that would be enough time.

Jon

we didn't get a call from car & driver in 2004??

and we had the coilovers on the car for SEMA of like 2004, purchased completely for cosmetic reasons. the eibach springs that we had on it before were not low enough for the wheels we had on it.

just out of curiousity on that article with the PTP rx8..... what kinda tires were they runnin.......becuz if they were runnin street tires with that kinda horsepower......if i had 330-390hp which ever was to the wheels i wouldve set myself up with some drag radials..... u know soft compound tires if there just doin that analysis for the magazine......we all know that the car will spin its tires or it will bog, thus bein the reason why i launch right at about 5.0-5.5k rpms..... so i get some spin, but itll hook but if u get some drag radials......slap those on ur rear wheels, n u should get a better 0-60 time..... unless that time they got was with drag radials

C&D runs all acceleration times on stock tires, with a full tank of gas, and on a level surface, with factory recomended air pressure, they also correct for altitude and wind. fyi

Nice Read, I wonder how reliable the apex and side seals will be over time, the RENISIS engine design with an aftermarket turbo.

Jon

It wasn't an option to use drag radials for the test. They really wanted the original wheels back on there, with the stock tires.

Thanks for sharing, nice job PTP....but I'd stick to Scott's setup (5psi = just a little less than 300whp). Honestly, I don't need or honestly want super high whp or psi. While I know low psi and high psi if not taken care of or setup correctly can still blow your engine I'd rather go the low boost approach for the life of my rotary.

Traction was the big factor there, Jon said it and so did R&T...so don't pay too much attention to those numbers.

Regarding the handling debate or how to rate it, after you take into account (slalom, lateral grip, weight distribution to give you a picture) you then have to look into the driver, road conditions, and avg speed at the corners to get a btter picture. In the end...it's still not perfect but we can safely assume one car is better than the other...as a general guideline at least.

Our friend got 13.1's with his setup...as stated with less than 300whp, and honestly that's more than enough for me. Who am I racing or trying to impress....I really don't give a heck about that stuff honestly.

In the end of the day...I use my car to get from point A to B 85% of the time, so 300whp would be more than enough to make that trip triple the amount of smiles on the smile-o-meter.

Thanks for posting...

Note: Oh yeah, the question was asked again how the Mustang with 300HP and 3,500 pounds of it's fat self can hit those 13.5's.....till this day I'm not satisfied with the response to that question. Ford is playing some games I tells ya...

dmp

Traction maybe?

Gearing?

If the car in the test was de-tuned to 330hp; i've forgotten if that number was wheel or estimated-fw hp - then it's right about where it's supposed to be, trap-speed wise.

We, as a group, should stop using hp vs e/t, and look at hp vs. weight. vs. gearing. vs. traction vs. Trap Speed.

Sephiroth

Good grief. Some of you people just keep attacking PTP again and again.

Since when have you all decided that mag tests are beyond doubt on target results and what you should expect on your car?

Jon

I would say traction and gearing played a large role in the mustang running that 13.5......

our car made 330rwhp which car & driver calculated flywheel hp at 390

and you can only compare hp with trapspeed. a cars trapspeed is directly related to how much power it has.... even if **** up the launch, the trapspeed will be almost identical everytime.

ET is directly related to DRIVER and TRACTION

for ex. supras run et's in the 10's lets say, at 150mph
rx7's run et's in the 10's and there trapspeed's are in the 125-140mph

no kidding, same people probably cry about "there's no parts for our car", makes you wonder why doesn't it?

Red Devil

Great work, Jon. I have no doubt your kit is worth the money.

For some reason, my computer won't pull up the article in a size that I can read. What was the trap speed in the 1/4 mile?

Interesting write up on the PTP (almost a) kit. I just picked up the mag today.

I do have do disagree with thier insinuation that the greddy kit is not a viable option. True, it takes some considerable effort to get the greddy kit to work well using the emanage (and it does work well if you a modicum of mechanical skill and persistance,) but it is doable. Plus the greddy kit is half the price AND INCLUDES THE FUEL MANAGEMENT. C&D states you have to pay extra for the brain PTP offers (it is a stand alone though.)

half the price and half the power, all personal preference I guess

Jon

carbon

we never said that the greddy kit was not a good option, and we didn't say that the emanage doesn't work. we actually waited almost 3 months for greddy to try and get us the dongles and the plug and play harness to use on our car 1.5yrs ago. but for the money you cannot compete with the greddy kit.

however as far as power potential goes, the greddy cannot compete

The Mighty Red

I'm happy to see such a great potential for power in the RX8. I'm interested. And when the time (and money) is right - I may just get that turbo. Maybe as soon as next year if things go well.

Good work - keep it up. I consider this good news.

Powa!!

Jon....what do you think about what Scott did with his upgraded Greedy kit?

Also, did you ever think about using Scott's Inter-X?

Just some thoughts...

Jon

as for what i read, he did a great job with the upgrades. and i have talked to him about offering the intercepter x with the kits but nothing was ever confirmed or anything.
