Has anyone custom tuned their Greddy kit on a dyno yet? It looks as though I may have to since I have the N flash, and I am curious if they were able to get anymore than the typical 240hp out of it and how much you paid. Also, if anyone is familiar with northern Va or MD can anyone suggest a good tuner shop.

 

I dont have a turbo but i think there are several people that got more than 240. I know someone here got 268WHP.

 

try Altered Atmosphere up 270 in Gaithersburg - they did an amazing job on my car (took a while, but the work was fantastic and it feels like the turbo came stock)

As far as dynoing, its gonna depend on what dyno you're using, your wheels, etc . . . . the only numbers you should pay attention to are your start and finish - I started at 170 and ended at 220 (this is with huge 285s in the back, no exhaust or anything else - just pure turbo kit).

Most of the guys with more than 240 are running more boost and have other bolt ons.

 

Did they actually tune your car, or was it just a dyno run?

 

Try Rp in Manassas. I was there Saturday and road in a turbo'ed 8. My god that freakin thing pulled hard.

 

RP performance doesn't tune, and they don't have a dyno.

They're great for suspension setups though.

Altered Atmosphere has the most experience in the area with rotaries - they tuned one guy's GReddy kit, installed and tuned a custom kit, and tuned my RX-8 - they also tuned my RX-7, and several others, but Mike isn't very good with the PowerFC - he's great with e-manage/s-afc.

 

I went for ride in that same 8 subdued. It really amazed me, I bought the greddy kit there on the spot! I just hope myne feels like that!

 

Hey CRETINX -

What did they do for you at Altered? Who worked on your car (Mike, Randy, etc.)?
When did you go there and why wasn't I contacted? :p

I go there to use the dyno, but I am a little leary of having them actually touch the car. They actually have very little experience with rotary motors and the dyno wasn't able to get a reliable RPM signal from the coils on my car or Jon's (philodox), making it difficult to get any useful numbers.

I am going to EIP in a few weeks to take another stab at some real, useful numbers.

 

KD Rotary, though further away in the Allentown, PA area, is well worth the drive. I used to go to them years ago. Dave really knows what he's doing and is great to work with.

 

Mazda Maniac, can my mechanic call you or you call me and I'll give you his number? I have the GREDDY kit installed with a Type RS BOV and when I get to high RPM's the car seems like its starving for something and my boost sucks? I'm usually sitting around 3-4 psi...I'm ordering the E-Manage tool today. My number is 701-741-6510

I went to the track yesterday and my best time was 15.09.............A stock RX-8 should do better than that........

 

...but what was your trap speed? My first time drag racing my old boosted Ford Probe GT, I went 15.00 - but at 100mph. Just giving out an ET won't help people diagnose what may be the problem. Chances are, it's the driver, frankly.




Launch...learn to launch.

:D

 

Mike and Randy both worked on my car for the dyno. I know they don't have much experience, but they're the closest and they've tuned my RX-7 and now 3 turbo RX-8s, so they're getting better, plus I always shoot them articles from this forum about tuning. As far as the install, it was clean and extremely good. The car feels good but I have a few plans to make it seem more like a turbo car from the factory, and of course pretty much double my boost.

They didn't tell me they had any problems getting a reliable signal from my car. I dynoed around 220.

Where's EIP? I'm considering going to Agile Auto just because they're so much cheaper. I'm also told Turbo Performance did a lot of work on RX-7s and Porsche Turbos so they're good to go to, but Altered is near the Metro and the least disruption to my life, plus these guys treated me right - they even got me a rental when the car took longer than they planned.

 

Dave basically built my RX-7. As far as motors go, he's where its at. I talked to them a while ago and they picked up a few renesis motors and were playing around with porting for turbo and NA applications.

 

Where did you hear that they "tuned" 3 RX-8s? Are they taking credit for Jon's car and mine?

EIP is in Westminister, Maryland. It is west of Baltimore.

THey got you a rental? This doesn't even sound like the same shop. What were you paying them?

 

try Car Version 2 in wilmington, delaware. they do a lot of tuning and performance work, and they have a dyno, and are pretty knowledgable. i have a buddy that works there part time wrenching on cars, and he has a ton of experience, from his grand national, building a bu-tang (grand national motor in a ford mustang), master mechanic for lexus, building his own turbo civic, etc.

 

They told me they tuned a GReddy turbo RX-8 and a custom turbo RX-8.

I'm in the DC Metro so Baltimore alone is a hike for me. I need to be near metrorail access.

I paid them $5300 installed and custom tuned.

The rental wasn't in the initial plans, but they were having trouble getting the oil line to stay so instead of giving me the car they decided to work on it an extra day and get me a rental.

 

Yeah, that is Jon's (philodox) and mine.

They didn't "tune" anything. They watched me tune. If I thought that my experience was going to be used to bolster their ability to extract money from customers, I would have demanded a cut of the action.

Exactly how did the "custom tune" your kit? They don't have any E-Manage experience and they don't have the software. They aren't even a Greddy Authorized dealer. You paid then $2300 to install the kit, which I guess is acceptable, but I'd want to see the MAPs myself before I accepted that they "tuned" your system.

 

Another *** taking credit from mazdamaniacs WORK ......

 

My reaction time was .22
15.09 in the 1/4
99 MPH

and yes this is my first time at the track

 

They told me they have lots of experience with the E-Manage and that they were GReddy authorized, and I saw them using the datalogit on a laptop computer to tune it. Frankly, the car runs well and I've had no problems with the turbo, so I'm happy. They're conveniently located - if you know somewhere better in the DC metro area that's not halfway to Baltimore PLEASE tell me.

 

what was your 60ft time? I'm guessing it was quite bad - something close to 3 seconds. Don't sweat reaction time at ALL. Seriously...when the light turns green sit there as long as you need to get a GOOD launch...figure with boost, 4500-5500rpms...feather out the clutch some and go! :D

99mph for 3200lbs (with driver?)...I'd guess about 215-225 HP at the wheels....

 

If you are dynoing the 8, you need to have the spark configuration set on the dyno to 720 degrees. (at least that is how I got it working on the dynojet at Rotary Reliability in Santa Ana)

Yeah, we did that and got no RPM values after 4000 RPM or so.

 

Odd . . . my dyno came out fine, and I watched them tuning it.

Mebbe they sorted their **** out?
