And Renwar1 on the boards got 206whp STOCK...what's your point?

 

Unless your FI is a supercharger in the future, i suggest against this. your gonna waste alot of money buying NA mods and then chunking them if you drop a turbo in.

 

I know what you mean, but its only a couple hundred bucks. Plus he can still sell it later on. I think there were quite a few people with the racing beat revi that sold it for the aem intake, or turbo.

 

by adding a center exit single 3" exhaust (comes out the rotary emblem in the back, the tip is rotor shaped for added coolness)/rp midpipe and tuning I managed to go from 218 whp to 270

has two resonators on it and the muffler, so it sounds nice.

 

Anyone else have anything to update?

 

Well...as far as gas mileage, I'm starting to notice that there isn't much of a change after having turbo. When I first got it, my foot was a little heavy, so my mileage sucked. I just got home from a road trip, and I actually got better mileage after putting the turbo on, than I did when it was n/a. Before I got to 264, and ran out of gas. This time I hit 252, and the light had just come on. Again, overall I'm very happy.

 

damn... lately I get about 175 out of a tank around town...

 

Are you hitting full boost every time you accelerate?

 

I think you need alot more tuning i going back and fourth in my mind to see if i should go turbo but when i see numbers like this it dissapoint me.I think you should be over 250 with no problems .

 

It is on a Mustang dyno with a conservative tune though. Somethings gotta be holding it back when some 8's can make 290hp with 10psi and a stock cat.

 

Keep in mind this was done on a mustang dyno, so this is more like 270whp on a dynojet. This particular run was at 9-10psi, I used 91 octane CA gas (which is about 89 in all other states) my timing had to be retarded quite a bit, my tuning was very conservative (look at my AFR curve), and all my runs were done in 3rd gear. So not to be too rude, but no, I don't need a lot of extra tuning. You need to pay more attention to the facts that have been clearly stated throughout the thread.

 

**** still i made 243 with only a 50 shot and some bolt ons Im thinking of buying the greddy kit from a member here that selling it but something keeps pulling me back from doing it .like rkostolni said i think something holding you back have you contacted scott for help ???

 

moostafa was the greddy kit worth it or would you say to wait for a better kit to come out ??

 

I honestly have no regrets whatsoever. Not only is the power difference night and day, but the torque is neck snapping. If you can find a used kit, then there is no question in my mind that you won't regret picking it up. Perhaps you should try to find someone in your area that has a turbo, and ask for a ride, or even to drive it. Then compare that to your car with nitrous.

If you are looking at my numbers to justify buying it, just remember all the variables. A lot of people don't realize just how bad the gas over here is until they experience it. I didn't even know until a few weeks ago. You should be fine since you are on the other side of the country. So you should expect what others on the east coast are getting, (280-290whp).

Were your numbers on a dynojet or mustang dyno. If mustang, what were your numbers without the nitrous?

During the tuning, we consulted with Scott for help. Both our tuner and Scott were amazed how much timing had to be pulled because of ping under boost, due to our gas. I do plan on leaning the AFR out a little in a few months after I buy a wideband sensor, but my tuner wanted to be conservative, because he had never worked with the renesis before.

 

Where is East Bay?

 

Its not a town, but an area. Specifically the Bay Area, but I live in the part known as the East Bay.

 

Damn, why can't anyone around LA have a turbo.

 

I met a guy at SevenStock8 with a Shinka that was turbo'd. I don't remember his name, but he said that he doesn't really post. Isn't Fanman in that area?

 

My car dynoed 213 and 243 with nitrous and this was done on a mustang dyno.thanks for the feedback i just dont want to make a mistake and have a car thats not realiable.

 

You can always take it off and resell it if you don't like it or don't think its worth it. If you buy a used kit to start with you shouldn't loose much. If you get it tuned though I very much doubt you will regret it.

 

I've heard there's better gas (not av-gas) available somewhere in Hayward or Fremont. Something like 95 or 96 octane.

I'll do a post on the WestCoast forum.

 

There is a place in San Jose with 100 octane gas. But I really don't feel like going all the way out there everytime I need gas, and also paying that kind of money per gallon.

 

Try xylene from the hardware or paint store. There used to be a thread 'round here somewhere about it. You can usually buy it in multiple quantities, even by the 55gallon drum. Just mix with your gas to the desired octane, it should be significantly cheaper than 100octane from a station.

 

I'm absolutely floored by those results. I have seen far more NA RX8's dyno in the 150-160 whp range. Never, never seen an RX8 dyno like this, even on a regular dynojet. You must have one of those freakish cars. Even with the full exhaust package (cat back & midpipe), intake, & CZ I have seen RX8's pull about 180's on a Mustang. Moostafa's dynos are right in line with what i would expect on a Mustang dyno.
