no real difference between l and m flash HP. this is a very interesting thread. i cant believe Fred is going to put his hands on someone else's motor besides mine- DAMN YOU FRED!! I WANTED TO BE YOUR FIRST :p :o :p :D :rolleyes: i seriously gotta get my funds in order and get that extra renesis to play with. Keep up the good work fellas!

Alright I'm calling people to help pull this beast out and hopefully my buddy can do it. Would a monday be good for you dave? Maybe this upcoming monday or even the one after? lemme know. Later and thanks for everything.

Well actually this monday isn't good because I'm taking my car to the dealership for them to do stuff. I.e. brakes/cd player/rear headlight cracked. Nothing effecting what we're doing. I just want them to fix this stuff before they say they won't. I'll call you dave and we'll figure a time out.

okie..
monday is when i was planning on getting the halfie on the dyno. turned the boost up to 12 and it hardly has traction in 2nd gear now.

I'm touched that you wanted me to deflower your car before anyone else. This bit of practice will just mean that I am better at it when I get to you!

I'll get the M after we do the porting and do a dyno b4 and after so we can see the results.

I think I'd get it before the port job. Don't want Mazda pulling anything stupid if they suspect the engine is ported. They pull dumb crap now. Don't give them an excuse.

I was just wondering but how would they know? I doubt they would like open up the engine to check on everyone that comes in? Maybe I'm missing something. If we wanna do it now I'm going in on monday I can have them do it. We can just dyno again. I don't really mind. 40 bucks isn't anything.

Unless you came in with a engine related problem I don't see how they would even know.

BTW...you did know the latest flash is on hold?

Chances are when you go in they will send you out with no flash.

Might want to call ahead...

They'll just drive every car RX8 that comes in "to evaluate whether it needs new brake pads" or something. When they drive yours they should be able to tell a difference and then have a look at the engine ;)

I just think that it is safer to get it done first. Some dealerships give a hassle over tiny things. Others look the other way when it comes to mods. What if we port this thing and then have a check engine light that keeps coming back? They're going to want to troubleshoot it. I'm not saying this will happen but you never know. I'd rather play it safe. Since we aren't going to increase the overlap at all, I don't suspect that you'll notice anything different from the idle or emissions standpoint. It "should" be just fine. I'm just overly cautious I guess. It should still appear to be 100% stock just by looking at it.

Very true RG. We have a little bit of time. I'm going to the dealership regardless on monday and I'll try and have them do the M flash but i'll update on what happens.

Are you planning on doing the porting in December or wait until after New Years? Depending on when it is in December will greatly affect my chances of flying since I go standby. January is easy though. I also need about a 2 weeks notice.

for me, the sooner the better.
but everything depends on everything else...y'know?

Damn! The eBay engine,tranny and ECU went for 4500.00. It would be nice to have a spare...

Vince

4500 isn't bad, but i've heard the trannies are weak--not good for turbos. is that true, or bs?

I see RG's point. But as of today the new flash is causing CEL's..

At least wait until they fix the code issue with the "L" flash.

IMHO

might as well just hold off then. we've already got the l flash dyno.

halfie did 386 @ 12.5 psi today :)
i would have turned up the boost, but my fuel pump is out of steam :(

This is a long thread, so for clarification "halfie" is your ported and turboed renesis right?

What turbo did you decide to use on it?

386hp to the wheels. Holy crap

no, the halfie is my fc.
i've been so busy working on everyone else's stuff, that was the first chance i've had in like 7 weeks to play with my own :)
turbo is a 62-1 with a 1.15 p trim hot side. i'm out of range as far as compressor efficiency goes. i think i may bump it up to a t70 or 72 maybe... but once i get my fuel stuff under control, i should be able to make 440 to the wheels with this one.

the turbo renesis isn't gonna be a dyno whore anymore. we were gonna do it, but the budget fell short at the last minute, so 320-340 whp will be the goal for that one. just enough to have fun with :)

forgot--the turbo for the renesis will probably be a t04b with a super h compressor. if the motor isn't happy with it, we'll bump it up to a 60-1, but that's too much turbo for the low 300's.

Wow.

i forgot to post this yesterday..
i dyno'd my car at the same place as the rx8. they had a problem and couldn't print up the graph last tiem, so they gave it to me yesterday.

here's the hp difference between 3rd and 4th gear:

looks like the aux ports only build power in 3rd!! i'd like to disable them in 4th and do another pull--see where that takes it.

this leads me to reaffirmate what i said earlier about getting the air in not being a problem... with the exhaust porting, i expect to see quite a bit more power gain when the aux ports open, but without sacrificing ANYTHING down low....hopefully. but i guess we won't know for absolute sure until the ported n/a motor gets dyno'd.

Sounds great. I figured since you were going to port your engine and then turbo it that FI shouldn't be a problem with porting, but are there any risks involved with porting and then a turbo? Thanks.

looks like a mustang dyno.

yea, the turbo 8 project is laggin' hardcore--not by my own hand, mind you...i've been ready for the last week and a half. i haven't totally decided, but the canzoomer ecu looks like it may be the winner. i'd like to keep everything working basically how it does now, just with added fuel enrichment and boost timing delay. i wanna keep the obd2 stuff as well.

it just looks like the stock ecu with a piggyback will be the easiest option for now...

and it was a dynojet @ 4500 ft elevation. same one i dyno'd my car on.

The average dyno for stock is what? 171hp I think. So taking away 9hp for being in the mountains looks pretty average to me.

yeah you are right but that is just the lowest dynojet number for an 8 i have seen. i watched 2 8's go back to back up in the mountains of washington state awhile back and one pulled 175 and the other pulled 179. that was a dynojet. that's at a higher elevation than 4500 im sure and they were both stock. but it was also early evening just after the sun had gone down and high 70's.

Maybe those runs were corrected numbers for elevation and temperature where this one wasn't.

if that was uncorrected, i'm really close to 400 @ 12.5 psi. me likey :)

You don't use correction for turbocharged cars. Since the air is thinner up high it obviously takes more of it to get the same amount of power. A turbo wastegate is set to open at a certain pressure. The turbo will just ingest more air to get the total air density the same as if it were at sea level. A nonturbo car will not do this. That is why they need correcction.

gotcha

thanks for the info :)
i turned the boost up just a tiny bit more ~14psi...now i can actually claim 400rwhp with some validity.

so snoochie, when we gonna do this?

Well if you have spare time we can pull my car on 2 or 3 sep days cause it'll take too long to do it in one day. Ima just get my Mom to get a rental and I'll use her truck for a while. We can do it down at my house. I'll clear room and we can use the whole garage. Lemme know if you wanna do this. I'll give you money for gas and whatnot coming down here. If we can do this we can do it soon.

alright.
let me know what day you're thinking of and i'll try to schedule around it.

do you know anyone with a truck? i'm a lazy ass and i wanna bring my air compressor. it'll save hours and hours...trust me

I got 179 at 5300 ft elevation back when I first got my car, and hadn't done anything to it except the Borla.

That being the case, you really should talk to Maurice (Canzoomer). He's been working on a supercharged '8 with his Canzoomer unit for quite some time now, and pretty much has all the bugs worked out. PM me for info.

already talked to him :).

The air compressor I have at my house says on it

6.5 @ 40 PSI
5.1 @ 90 PSI
125 PSI MAX

It's pretty big so will this work so you don't have to tote yours down here?
Also anybody know what the cheapest car rental place is? :D

First day we could start on it could be monday I suppose at around 1ish.

that should work for the air tools..

I guess you guys don't want me to come out there then?

i don't know what's going on.

Kinda mad at myself for not pushing this forward so here we go...

Does monday work for you? I'd be game for it. I would say I'd pick you up but I wouldn't have a car to drive you back with. :D Also could we do more/maybe finish pulling it on wednesday? In the same sense we could start on wednesday if monday isn't good for you. I would just like a timetable down so I can know how long I need the rental for.

Do you think it'll take 2 or 3 days to pull it? Probably depends on our schedules and how long we have to pull it. For me I could work on monday from 1ish till sundown or later. So here's a recap...

1. Can you come down on mon the 6th/wed the 8th?
2. Also what about the next mon/wed (the 13th and 15th)
3. How long can you stay down here if in fact you can come down on those days?
4. Is there another day that works for you? I can switch up my schedule to fit what you need...

And where is the cheapest rental place??

Alright hopefully this thing gets underway now.

I would like to show you guys how to construct a very cheap but very useful flowbench so you can test those ports. No more guess work! If you've got a shop vac, Home Depot has the rest.

guitar: If you've still got those ported housings lying aroudn unassembled, I'm wondering if you can make a mold of the runners and ports and send them to me for flow testing. I'd really like to have an original untouched port mold too. Here's a link to a website that shows how to do it on piston engines. Yes it has to be apart. The technique is the same. I've done it with some of my housings. Once I get these molds, I can make a copy out of fiberglass or plaster and then flowbench them. I don't even need a motor in my possession. This is a neat way to develop port shapes all day long without ever touching a motor plate. Once you get it where you want it, then you try to copy it on the real thing. You can get in the ballpark. Flow testing isn't accurate from the standpoint that you know how much a rotary engine actually flows. It is a good frame of reference though when you are comparing it to other parts of the intake and exhaust system and to tell if what you did actually was better or not. There are other things it tells you but I'll get into that later. Try this and see how it works. If you get one good, send it to me.

speaking of that..... check your pms in a about 1 minute:)

very good idea!!!
only problem is it's been 30's at night and 40's in the day here....it'd take forever for the rtv to dry.....i'd get killed if i brought the irons in the house. :p
