Now I KNOW you go to PSU haha. Oh and don't sweat it...I'm not Mr. Super Uptight.

Well, Just found this thread on this forum. Haven't posted here much. I am usually on the rx8club forums. Those videos labeled 'philodox' are mine. If you want to follow the thread on the rx8forums here is the link. I'll be hitting the dyno this friday the 21st. Sorry if the 8 isn't as impressive as the 7's are with turbo. I am only running 7psi for now. However, compared to stock, it's significantly ahead of the power curve. Will post hard numbers this Friday for your critques/flames once I get back from the dyno.

So far I am very pleased with the kit. It can't compare to a properly setup 7 in anyway and I'm not even going to begin to claim so. Can't make everyone happy.

p.s. sorry for the beginning of that 2nd video. I am rather new to Windows Movie maker and really wasn't sure what the heck I was doing when I made it. Now I know how to clip videos and won't be making the same mistake twice.

Its Montgomery Village Ave.

Everyone is welcome to come over to Altered on Friday and watch us tune it or blow it up.

Thats sweet. There all great vids. Wouldn't mind having either of the cars.

Aside from high compression the exhaust sucks ***** for turbo. The non-peripheral port exhaust is not as good for means of spooling up the turbo because of the less energy that the turbo sees from side ports, thus why it's a good candidate for s/c. Think of it as going from from pport intake to stock side ports, just for the exhaust, it just doesn't flow as well.

Hey, just in case you're referring to my post, I didn't mean it negatively or in a way to diss the the 8. In fact, I don't think people should be comparing the 7 and the 8 at all. Handlingwise, they both handle EXCELLENT (in fact, I found the 8 much easier to drive at it's limits...it's much more predictable and forgiving). But when it comes to power and overall performance, it's like comparing apples and oranges. They're two very diff cars, and the 8 certainly wasn't made to be the next 7.

Oh, and your numbers do look great. I'm sure you feel a vast improvement. I'd love to check it out sometime

Steiner, THAT'S pretty much what I had read in the articles. Unfortunately, I'm not too familar w/ the details haha. Thanks Ron

i test drove the 8 as well and was quite unimpressed. dont get me wrong... its definatly a fun car (and ive been recomending one to my dad for some time)... but it can not replace the 7. the handling on the 8 is very good, and quite predictable at the limits (as FDNewbie also pointed out) but it simply lacks the power to succeed the 7. so final MY final verdict on the 8 would be: good handling, not nearly enough power. as far as simply the handling, a good analogy would be a rollercoaster... the 7 is like an old wood coaster, and the 8 feels more like a metal frame rollercoaster. both fun but in different ways. the only thing currenly stopping me from buying the fun yet underpowered 8, is mazdas other contender... the miata.

i currently have a miata, and a 7. the miata handles very well (with a few upgrades to the suspension) and feels even more predictable than the 8 at the limits.... its really no more than a go cart. and yes, the miata is underpowered but almost equally as fun to drive as teh 7. my point is...... that all i want to do is go out and buy another mazda sports car to add to the stable... but i see the miata on one end of the spectrum, and the 7 on the other... and the rx8 just feebely stands somewhere in the middle of the two... not quite a miata, not quite a 7. personally, (already owning a 7) id rather stick with my miata and throw a turbo on that... rather than screw with the 8. just my 2 cents. -heath

One thing u guys gotta remeber is that the rx8 wasnt built to beat the 7. It was built to give the 7 a chance for life again. So everyday I praise the 8 for the possibility of the 7 returning.

speedx7

nice vids man, keep them coming

speedracer2235

I agree with rotoryweaponse7en. The Renesis is a bit different than the 13B most of us are used to. I want them to do a rotory Miata just as bad as another 7. I believe the renesis will respond very differently to the same mods we do to the 13Bs.

Not sure if you had seen the video.. but the T618Z turbo that comes with the Greddy kit has pretty much instant spool. From a stop it spools before 3.5k RPM.. while in boost, spool up at gear change is instant.. I don't see a problem at all.

d0 Luck

on the 3rd vid, if the driver was actually gunning it all the way to redline, it is pretty slow when it caught up w/ one of the civilian cars.

but for the achievement though

Jaime Enriquez

T618z's are also incredibly small....no wonder they spool and hit boost so fast! Let's see a TD06-25G on that motor...or T88 (hehehe)

philodox

But they are perfect for the application. @ 7psi it works wonderfully.

NEMESIS8

OK guys, I started this thread with the intent to show that the 8 is moving forward with FI. Please be patient with their efforts, we all want more power, and this project will only help the rotary engine come back to haunt all those piston heads out there... The aftermarket for the 8 is growing every day, so this is great news for all of us rotary owners.

its not that your intent for the thread was wrong, its just that the video was 16 freakin minutes long and it only needed to be 1 at most

philodox

eek! sorry about that one My Windows Movie Maker skills are still getting tweaked. Next one wont' be like that now that I know how to clip the videos.

NEMESIS8

HKS has a supercharged RX8 in Japan with an aluminum intake manifold - have a look...

BMS2004

yea I didn't say it wouldn't work I just said not as well, hence why they're using tiny turbos. My point was, bolt on a upgrade turbo for a FD and you will not see the same performance and I tried to explain the reasoning behind it.

sorry, damn browser went haywire.. wish I could delete posts in the editor.. heh..

Oh I understand and respect what you are getting at.. But, you can't compare the 7 with the 8. The jury is still out as to how far the Renesis can be pushed. There are some people running 75shots of nitrous with success. Another 8 owner I know has a T3/T4 Hybrid as his turbo of choice for his 8 which is much larger than the T618Z.

This coming year will be when we start seeing a lot of forward progress in finding out how much further the Renesis can be pushed, especially since the RX-8 is starting to get support from manufacturers in the form of more parts and mods. I know that the Renesis will in all likely never see the same potential that the REWs can achieve, but I don't think 300whp from a Renesis is unreasonable. For a person who wants a dedicated street car, 300whp should be more than enough.

Now for my particular situation, I will eventually tune up for about 9psi. That's where the stock injectors run out of fuel delivery capacity. For the time being, I'm happy with 7psi and will tune for that. If I can get 250whp out of 7psi then I'll be very happy. I'll see this Friday when I hit the dyno for the first time to get a baseline.

Well done!I`am very impressed with your efforts!

Got back from the dyno today. Dyno'd at 240rwhp. Stock I was at 174rwhp. Nice increase with only 7psi and a stock tune for the emanage. Can probably squeeze another 20-25hp through a proper tune at 7psi.
