Yeah, I certainly agree with that. The bang for the buck on some of these initial kits doesn't look too good. I guess though like everything else, the first version of something won't end up being either the best or the cheapest. Somebody has to be the pioneer though.

Why would they say 220 at the wheels with an intercooloer yet also say expect 50 more hp and 50 more torque? Even if the car was dyno'd at 190 that would be 240. In order to get 220 at the wheels they would be saying it originally dyno'd at 170.. kind of low to me... I really like the sound of 200 torque though All of these figures were coming in at around 4,000 rpm....

but anyway.. I called them up and they said to expect their website to be updated within the next few weeks. They are working on the final touches for their RX8 supercharger page.

I know i'll be looking for it.

 

my personal opinion after having discussions about the unit at sevenstock is that its undersized. id personally wait on getting this setup until after hymee gets his done.

 

Actually the PROTOYTPE package that Pettit brought to SevenStock, was quite impressive... Cam let me take test drive and beyond the un-regular idle stall and SC whine, the car felt normal. That is until you stepped on the loud pedal... The SC really pumps up the mid-range and the car definitely picks up MUCH better than stock. With almost instant boost, you find yourself short shifting (at least for the RX-8) at around 7500-8000 or so. The SC car feels, and I suspect it is, "much" more torquey and stout. This will be a very nice package when final details are worked out. Well worth a look IMHO... this thing would kill around Laguna Seca.. is all I kept thinking!

The car sure looked fast... I wouldn't have minded a ride in it at all.

 

I called them up a few days ago and the power was still out for them. Pettit is based in Florida and they got hit hard...

They told me not to expect their website to be updated with product info on the RX8 system for a while.... at least a few weeks... hopefully not much more than that...

Rrrrrrr

 

I've nothing to say to the actual topic, except best... quote... ever....

 

The day has finally come....

http://www.pettitracing.com/flash.htm

It looks different from what we saw at Seven Stock.. Looks like they have been doing some updates since I last saw it...

 

strut bar still sems to be missing

 

That's just the nonintercooled version. The blower is rotated 180 degrees the opposite way too. I'd like to see under the engine cover at the intake manifold.

 

They tested one for the latest issue of MT....just got it a few days ago.

They report that they are still having problems tuning the ECU...so still not getting what they want out of it........more to come on that

But they say they had 2 versions working. A low and high boost. The high boost came with an intercooler. I don't remember the boost PSI's...but will update later. (I think like 5psi and 8psi)

I will try and scan the page and post for everyone tomaorw


***Edit***

Well crap...someone already posted the review

https://www.rx8club.com/series-i-major-horsepower-upgrades-93/motortrend-review-pettit-sc-40803/

 

They dogged them... I bet Pettit is mad about that.. They can only blame themselves though for producing a car for them to review that isnt the final production model working perfectly.

 

For $ 5,000 a 4 tenths of a second in the quater mile and a zero to 60 reduction of about 3 tenths is **** return on your investment.

 

the comparisons doesn't show much as far a quarter mile times. First, did the petitt rx8 run a 14.5 prior to the s/c? Or is that the "magazine" tested time? I've only seen a handful get that time and only one that went below. Mostly I've seen very high 14's and low 15's. So how many tenths of a second shaved doesn't mean anything if its the latter there is no base comparison. Wait til the final product then judge.

 

If you spent $5000 for a supercharger for a car that is already supposed to run mid to high 14 second quarter miles and you are still in the 14's, you got ripped off. For 5K I'd better be seeing 12's.

 

agreed, well from the article seems like they have a lot of kinks to work out. If they correct the mentioned problems would that equate to better e/t ?

 

With 50 hp more, they should see about a full second off of the quarter mile. As I always say, tuning is everything.

 

Much more updates to their site are now available..

I know they are both twin-screw designs, but are there any subtle differences between Autorotor and Whipple?

 

They are both owned by the same parent company, Opcon. Whipple is what the "Lysholm" brand is sold as in the USA. Have a look on Kenne Bell's website for some good comparisons of the Autorotor and Lysholm/Whipple.

Basically, the Whipple is a cast body, the Autorotor is "billet". The Autorotor uses larger bearings, and the ratio of the female and male rotors is slightly different. Also there is some differences in the drive gears.

Cheers,
Hymee.

 

Thanks for the tip Hymee.

So, I suppose Autorotor's twin-screw design is an evolution of the Lysholm type?

 

I think it is more of a quality / cost of production issue. The Autorotor is higher quality, therefore more expensive to produce, as far as I understand.

Cheers,
Hymee.

 

what's the self contained lubrication thing?

 

I belive that the Autorotor is an extrusion not "billet."

 

So with the autorotor you dont have to drill into the oil pan. Is that a big deal?
