Yup, it is indeed. :D

 

so how do you control that walbro? Inquiring minds want to know...

 

How loud is that exaust setup and what muffler etc is on there. Is there anyway you could post a video or sound clip?

 

Where on LI are you? I'd love to come see your car.

 

West Babylon, as soon as i get my comp back i will set up everything, sound clips, video, and sheets, im on an old *** laptop right now that is just getin by runninn. soon boyz soon

 

The exhaust has toned down acutally since the turbo, the turbo acutally works as a little bit of a silencer in this case. its sounds perfect, i still runnin a lil on the rich side so im backfreing but im gonna talk to bennt at greddy for the new map

 

Did you use the Walbro kit for the RX-7 -- or did you just use the universal kit? I tried to order one yesterday but they don't have a kit for the RX-8 yet and didn't know if hte RX-7 kit would work.

Are you using the stock injectors or did you upgrade those also?

 

can somebody loan this brother a scanner to get the dyno plot posted??

:D

 

dude...i'll be in Newark all next week...

hey Mugatu..wanna ride over and see this thing...i can take the New/Penn station train into manhattan and we can hook up somehow if possible....

 

Its reallythat bad? What size tiresare you going to have to upgrade to? 245/45 or somethinglike that? Or areyou probably goingto go up to 19/20s?

 

Actually... if the Mazda's 238BHP number is correct with 185RWHP and 22.3% drivetrain losses, then 268RWHP will equate to about 345HP (268/0.777) at the crank!! Just doing my part to get us excited even more!

I think you guys are being a little too optimistic.

1) The RX8 does not have 238 hp stock. The 180 whp is not close to what a
238 hp car should be putting out. We are probably making closer to 220
hp. The S2000 is 240 hp & it dynoes low to mid 200's.

2) Porsches (996) & M3's dyno around the 260's, so you are really looking
around 320-330 hp at high 260's whp. Still pretty damn good.

 

here we go again...

I used the Universal Kit, injectors are still stock, im thinking about going with 19 inch rubbers but as of now i just dont have the money haha, today wasnt a good day one of my plugs fouled out, so i gotta swap them out, MORE MONEY plugs aint cheap either,My car will most likely be at the Hot Import Nights show in Atlantic City N.J im not sure of the date but my sponsorship is pending right now.
peace

I saw a stock s2000 put down 220whp.

Those who think the RX8 really DOES lose 40-50hp thru the drivetrain are kidding themselves.

 

^no kidding, ...are you sure it was stock. that a lot of power to the swheel from a car with 240 at the crank...unless honda messed up...but in the owners favor:p

 

Correct me if I'am wrong, but I believe what is trying to be said is that maybe the 238Hp rating of the RX8 is wrong. If you figure about a 20% loss thru the drivetrain and everyone seems to be getting around 180 whp for a stock RX8, that would realistically put the rated hp of the RX8 at around 228hp .

 

And surprise surprise, that is exactly what our UK cars are rated at 231ps (228bhp), spookey eh! :o

 

110% sure the car is stock.

Honda - Under rates HP

Mazda - Over rates HP

 

haha damn you mazda. ah well i still love my baby:D

 

Well, not quite stock--I have an aftermarket radio, hybrid brake pads, DOT4 brake fluid and Mobil 1 oil. :p

That was uncorrected, on a nice, cold, foggy day, when most of the RX-8s were doing 185rwhp. Corrected, it was 210rwhp. Stock '04 and '05 S2000s typically dyno at 205-210 corrected; pre-'04 S2000s typically get around 195.

So, as dmp said, it is likely that Honda significanly under-reports the new S2000, and it is likely that Mazda is optimistic on the RX-8

 

If you look at a 18% driveline loss, the 205 whp of the S2000 would = 250-255 hp at the crank. The 195 whp for a pre-04' S2000 = 238 hp (right in line with claimed 240 hp). For our cars the 185 whp = 225-226 hp. That seems in line with what many of us have surmised. The european spec of 228 hp may be a bit more realistic than the stated 238 hp.

Also wasn't this the day that an RX8 put out 206 whp ? In that case it may very well be that the dyno was showing optimistic #'s for everybody.

 

Yeah, it was that day, but that was only one car; all the rest of the RX-8s were right around 185. I'm inclined to think that the dyno was reasonably accurate, since my S2000 was completely in line with what stock S2000s get, and the rest of the RX-8s were where one would expect them to be. I believe that that one RX-8 which did a 206 (uncorrected; probably 197-198 corrected) was running significantly leaner than the rest of the RX-8s, and there may have been something funky, of which the owner was unaware, about that particular car.

 

Omi,

You are a very bright guy, you were at Racing beat... did you see the engine dyno for the 8? It was 208-212 period. That's it. I have no idea why people continue to think this engine makes any more power than that. Mazda did a great job with the drivetrain on this car. Anyways let me do the math with those numbers

lets be optomistic

182 (close to avg dyno for rx8) / 212 = ~86% or 14% loss

so

268 * 1.14 = 305.52 which is WAY more in line with what 7lbs of boost should be making over the stock 212.

I am not trying to insult Omi or anyone else, I am just asking the people here to get realistic. You bought a car with 212Hp at the crank... not 228 not 238. The engine dyno doesn't lie, Mazda does... emprically if you look at the evidence, there are very few companies that lie about HP numbers more than mazda. I do however believe that a well tuned 13B-MSP will make ~240 at the crank, just not hte way that mazda sells it to you.


Bleh...

what about snoochies 150 whp stock?
