As will I. This is very cool. But one major question at this point... what are you doing for engine management?

XDEEDUBBX

Yoda Man Ito! Make It Happen ***** F!#@#!!!!

red_rx8_red_int

That is the 64k question!

Aoshi Shinomori

Charles isn't using any engine management I don't think although he is only running a 55 shot(maybe 75, don't remember) and he said everything is fine. I'm sure Ito has some sort of solution, maybe an emanage or canzoomer? Maybe he's going to see if the stock PCM will handle it?
Question about running rich/lean. If you were running rich like most rx8s meaning that you're not burning all of your fuel, wouldn't something like nitrous or FI help to lean it out by increasing efficiency? I may be assuming to much, but would like to hear an expert's opinion.

BaronVonBigmeat

A few random questions for Mr. P&P once he's ready to spill the beans:

1) You said earlier you have enough work and won't be doing this for customers, but how much would you guestimate that another shop would charge?

2) You were having transmission troubles originally, right? Did you beef up your transmission or replace it altogether?

3) What ECU?

4) Are you still making 240 rwhp on a streetable motor, and also what's behind the big surge in power at the upper end of the graph?

5) Any other mods this time, or just port + nitrous?

Snoochie

Charles said he was using wet nos so the ecu problem wasn't a problem. I don't know if this matters with p&p, I don't know if this matter cause he's using such a massive shot, just reitterating (sp?)

Not to rain on anyone's parade, but why don't you guys actually wait for proven results to verify the claim this time? Don't jump the gun to never get any results. When they come in, then start asking questions. I don't want to see another thread where someone makes a claim but doesn't answer all of the questions for whatever reason. Ito (P&P): I'm not trying to be a ***** to you here but to avoid another situation where you get frustrated with us and end up going over to nopistons.com and badmouthing us again to all 4 of the people on that entire forum, verify your claims and post EVERYTHING you did to the car. If you have a secret about anything, please don't post anything at all. If you are willing to divulge all, then please let us know. It's all or nothing. Saying that, good luck to you and I hope you hit the numbers you are hoping for. Please don't get all pissed off again just because there may be some doubters.

Mr. Port & Polish

My Rx8 made 242 rwhp, to that you take away about 17 hp when ignition timing is being retarted for nitrous activation. That brings the engine down to about 225rwhp, out of the 150 nitrous shot into the engine, there is about 10 to 15% hp loss through the drivetrain. I've just about seen a 25hp loss out of a 150 shot to the engine, landing a 125hp increase to the 225rwhp giving me 350rwhp. Not only have I planned everything out, but I have done all kinds of test and tunning with my kids 91 Rx7 6 port streetport on nitrous(most hp with nitrous I pulled out of her engine, reliable, was 261rwhp and 217tq using stock ecu and afm,I later dynoed 280rwhp but I could hear detonation and backed the tunning down to 261rwhp on 93 octane) On my Rx8 I could even go higher octane and shot the engine with a 190 to 210 shot but that is not my goal. My goal is 93 octane and reliable horsepower. A 150hp nitrous shot using 93 octane and adjusting ignition timing will not comprise reliability. In extreme cases with full race cars I have used up to 230 n20 shot and ran a full drag racing season (over 100 quarte mile runs) without tearing the engine apart. When I did tear the race engine apart I did not notice any abnormal premature wear on seals. This was done with fine tunning of course. If the engine is not tunned properly seals will wear down..

Mr. Port & Polish

I'm not sure as far as total cost. I did spend 1,200.oo in seals. corner seals and springs, side seals and springs, apex seals and springs, oil seals, complete engine gasket set, oil seal control rings and springs. To that you add labor, every shop has different labor cost. I want to add that I will not except work. nothing personal to you or anyone else.

Mr. Port & Polish

I payed close attention to the closing edge of the intake port. My ports are on steroids HUGE.. I'm going to brace my tranny, but G-Force engineering transmission is going to look into building me some stronger gears. (I have shattered a couple in the past) I swear Mazda should let me build an "Ito-Spec" Rx8 in there performance department. Some people would get a serioulsy faster, stronger Rx8 from the show room.
It's all possible, I'm basically doing something they could offer for the serious enthusiats. The difference would be a higher sticker price.

Mr. Port & Polish

Yes I drag race at e-town all the time. Velocity red Rx8 Stats: 5'10" 225lbs brown coco skin, curly black hair. Next time your around and you see me in the staging lanes just stop by and say hello. I love to talk about anything rotary.

Mr. Port & Polish

I own a rotary performance shop. But I'm currently not taking in work. My shop is me, I am my shop. meaning I'm a one man operation.

Mr. Port & Polish

The Rx8 runs extremely rich from the factory ecu. I will not touch the ecu and concentrate on fine tunning nitrous mixtures with a wet nitrous system. The biggest problem is too much timing advance. That is where all the reliability will come from. controling the already super advanced ignition timing the Rx8 comes with under a load.

Broke_Apex_Seal

Ito why all the hype man, just do it then post. I hope it woks out for ya!! Please post some dyno graphs when you get them.

Mugatu

iTrader: (1)

That's the way he posts on this forum.

Ajax

Ito:
Any pictures of your ports, just for the droolfactor?

Mr. Port & Polish

no hype just answering some questions. O and the real hype is I'm excited about this renesis engine.

Genom

If someone ever posts some pics of the ported engine, I'd love to do something like that to mine when the warranty is gone. Which should only be another 12 months for me.

Sadly, I dont know enough to figure it out on my own though. Looking forward to the article.

Aoshi Shinomori

Just a question to the naysayers. What is the point of even posting, if you have nothing positive to say? People post on this site about which way they have their toilet paper set up. Ito is letting us know that he's back, and ready to do some awesome tuning on his RX8. This is good news, at least to me. I want to see the potential of this car. If you don't then that's fine, but you posting things like this it doesn't do anything but ruin Ito's respect(or anyone undertaking projects for that matter) for the forum as a whole. Remember what happened last time? I don't see people attacking Richard Paul or Hymee, or Charles like you do to Ito. Leave the guy alone and let him do his thing. I for one want to see his 8, along with others rock some serious speed.

davefzr

Yeah well Hymee and Richard are taking a different approach in that once they finish it will become available to those who want it. Ito does not.. Thats why everyone got on his case last time.. and it looks like it's happening again.

reddragonmd

I just agree with the whole "all or nothing" comment someone made. If you have secrets, and want to be secretive about your work, dont bother posting anything. I think that was the reference made to another thread started by P&P before, that turned into a huge cluster f**k of arguments, and flaming.

If someone wants to posts dynos, fine. But if someone asks what mods youve done, or how you went about it, dont say "i cannot devulge at this time". Isnt this forum suppose to be an e-family of 8 owners?

And this is speaking in general, not directed soley at you P&P. But i remember that thread from before that turned bad real quick.

93silverFD

Hes not hiding anything. He ported his motor, and is now adding a 150 shot of nitrous, plain and simple. Get all the ports as big as you possibly can, including the exhaust, smooth out the edges, bridge the tri-ports, and v-wallah, you have an RX8 that idles like a monster from the rotary lagoon and makes great power up top. You can do all that yourself with a die grinder, 2 pieces of plexi glass, and a perminant marker (really).

Its ok ITO, I still love you.

reddragonmd

blah blah no one is crying, were asking to not have this thread become another failure.

And i personally would love to see an rx8 making that kind of power. :o

zoom44

no its not dave. mr. pnp has only just laid out his plan. once he is done and ready to run then there will be an article in RXTuner with the results.

davefzr

So how are results available in RXTuner the same thing as Hymee or Richard offering their product to the public? Unless your saying that RXTuner will be his springboard to offering such a product nation wide, but I am not sure your prepared to say that.

but anyway.. back to the thread.. good luck wtih your work.
