Having two other local turbo RX-8's to go to the drag strip with will give us a better picture of what is really capable.

Totally agree. All the dyno days I have been too have yet to see a RX8 eclipse 300 whp. I know it has been done by very few people but still have never seen it.

You laughed at my virtual dyno showing 380hp at 16psi yet you somehow found some credibility in Turblowns claim of 423 at 10psi .

All very confusing isn't it ;)

9krpmrx8 03-11-2014 02:42 PM

I believe making a 400WHP once or twice with that setup, before grenading everything is possible. Doing it repeatably with that setup, no way. Do I think it is likely they fudged the numbers? It is likely, because it is Turdblown we are talking about. But (and this is a big but to me) the owner of that car is a stand up guy and if he says his dad witnessed it making that HP on the dyno and there was no apparent funny business, then I believe he saw what he saw and experienced what he experienced driving it.

Your virtual dyno while cool, and fun to play with, proves absolutely nothing to me. It's no different than the dyno function built into the Cobb and that is useless as well. If you buy it, then that is cool. But until I see video of you running 12's in 1/4 mile then it is just all fluff and useless banter to me.

pdxhak 03-11-2014 02:46 PM

TBH screw dyno numbers and dyno queens. What can the car reliably do on the street and or track is what really matters.

9krpmrx8 03-11-2014 02:53 PM

Yeah I have heard everything here and after driving a few boosted 8's over the years, running around in Vegas with MM and them, etc. I can honestly say the only one I was ever impressed with was Olddraggers Pettit SC 8 when I drove it out in GA, that thing was a hoot to drive due to the instant boost. Shadycrew31's was a blast to drive when NA as well, almost like mine was on nitrous but all the time. Hopefully when mine is back together I can get that type of drivability and if I get my 1/4 times to low 13's. Then I will be happy until I figure out what is next.

9krpmrx8 03-11-2014 03:00 PM

I can't wait to drive Martin's modified Turblown top mount setup, he is almost done tuning with Kane. He moved to it from a Greddy with the BNR upgrade that was fun but from what he told me, still could not pull on what he considered lesser cars that he expected to beat.

I don't doubt that he saw what he saw for one minute . I have seen the video as well and the numbers are pretty clear . 423whp @ 10psi . There is no secret about the 10psi ......... it is on the video .I even remember asking for clarification at the time and was told "yes definitely 10psi ".
We all believed it at the time , I think because we wanted to believe it was possible .And at the time "it's all about flow- boost is meaningless" was echoing in MM's follower's ears .

Let me state this quite clearly ..... that setup never made over 400whp - not even for a second . The only proof that it was a con job you should need, is that they claimed to do it at 10psi.

People that fit big turbos to these engines are not getting it IMO . We have yet to prove that 400+ whp is sustainable, so fitting one "capable" of that is just making the car less fun to drive because of the extra lag.

9krpmrx8 03-11-2014 03:37 PM

We shall see when he comes down to run. He says it feel faster than his BNR Greddy setup ever did and he has driving a turbo RX-8 longer than most.

Yeah .... most BNR setups never even get remotely close to performing as well as they are capable, because people can't work out how to increase the boost .

Did I mention I'm running 16psi ? ;)

pdxhak 03-11-2014 03:47 PM

Brettus, where is gregs with his updated turbo kit? Any numbers you can share?

pdxhak 03-11-2014 03:48 PM

My BNR setup seems to run out air up top. No issues with having enough fuel or holding boost. I peak at 12 psi.

That is not the turbo - there is plenty left .

Could be but I have no idea. Just going off what MM said a few times to me when he had tuned my car. I should have mentioned that in my previous post.

Well MM is full of it - he even had us convinced he made 423whp @ 10psi once ! LOL

You are lucky you got your money back man. I am so glad it all worked out for you, I can't wait to see some 1/4 mile run video. If I were to ditch my low mount setup I will likely go with the PTP kit, I plan on picking up a kit without the turbo before they run out of them.

Thx man, it was a battle royale fighting him.

I've contemplated going to the strip more to get data logs and just plain fun. Even if the car is swift I am not :lol: I am getting close to a dyno session tho. Was hoping for March, may wait until April. I'll have to see how work goes.

If you get the PTP pipes I'll gladly share whatever I can of my setup. I'm sitting really happy at about 14psi right now and it puts a smile on my face every time I hit it :)

pdxhak 03-11-2014 09:38 PM

During the summer PIR has Friday Night drags. I have been tempted to go a few times just to see what I could do but something always comes up.

firecran 03-12-2014 10:52 AM

It would be nice to see some 1/4 times and trap speeds of all these boosted rennys.
Curious to see if how fast they really are but I fear it's all a bunch of talk :dunno:


.

9krpmrx8 03-12-2014 11:16 AM

I drive one and feel the same way.

pdxhak 03-12-2014 11:40 AM

Same here but it is all relative to the running condition of the car, who is driving and how hard they push it. IMO there would need to be several owners do it in varying conditions to get any consensus.

firecran 03-12-2014 12:16 PM

Yeah, it would be nice to have a comparison between different kits and/or engines.... even pistons could participate.

I have, I've been kept in the loop from both Dave and the owner regarding the S2 that's at Dave's right now throughout the entire project and know what's worked and what hasn't worked from the day the owner dropped the car off until today. I sometimes act as the intermediary between the two when they have difficulty reaching each other.

The turbo doesn't actually work with the low mount kit because there's no room for both oil and water lines on the S2. Why do you think the turbo on that specific S2 @ Speed1 isn't the standard Turblown one? I'll let the owner chime in if he wants to give out any specifics.

Believe me, I don't like the way Elliot does business, but I also take Dave's opinion very seriously since he has been making a very concerted effort to getting the S2 Turbo project done using a Turblown-built kit. He's spent a great deal of time on trying to work with the ECU. So in terms of more experience, who else are you really going to ask?

save 5K more and do the 13brew swap :D but budget! don't overspend.

I had it priced at 20k + car to do a REW swap and still have all the interior devices work, slightly less if you keep the MSP. Remember, you still need the stock box and MazdaEdit to turn off codes and such. It's all projected, and no one's done it successfully, but that's what I've gathered so far.

These comments are for S2's that want to pass emissions with a functioning dash, power steering, A/C, etc. If you're not in that camp, it's a lot cheaper.

If I had the desire I have no doubt I could build an entire turbo'd 8. I know enough and enough people I could develop an ECU flash myself. This would be my 4th rotary car and I have or know enough people to make any of these kits work (including and Fab work needed). Point is, I have other hobbies and am starting a new business (3D modeling) and neither have the time or desire to do it. This is why I was looking for a reliable bolt on kit for modest hp gains. I am not going to race or autoX, but I live in Denver and am already at a significant hp loss from altitude so i was looking for a good option.

I doubt this. No one knows anyone who has made this work or can make this work at the current time. This isn't the old days of the Microtech / Haltech where you wire up the box, change a few cells and boom you have a running car. Have you seen how locked down the S2 ECU is? Any of the 09+ Mazda ECU's are just as FUBAR'ed. If you thought the 8 ECU sucked, the Mazdaspeed3 ECU is just as bad, if not worse. ABS wire goes out, your boost control goes crazy. There are people with your background who've given up after spending a long time with this box because the ECU just will not respond to flashes. People haven't gone past the flash limits on the ECU's and have had to buy new ones just to keep experimenting.

I don't think you can do it. I don't think it can be done. But prove me wrong. The entire community will thank you for it.

That's not to say that the flash is the only solution to a turbo'ed S2.

After tuning multiple s1 turbo 8s with both M/E and cobb . I can tell you that if someone fits a turbo to an S2 properly ...flash tuning it with M/E will not be a problem (to someone who knows what they are doing).

And.................. it will be the best solution.

Roen 03-14-2014 04:57 PM

Ha.......I wish I could tell you what I've seen on both the installation end and tuning end on this project, but I don't want to steal the owner's thunder.

The Aussies abandoned ME, didn't they? Now they're doing MoTeC + ME? or just straight MoTeC? I forget, you'll have to enlighten me.
