Can anyone make somerecommendations for cheap ways to gain some power? My boss just bought a Saturn Sky and I can't have him showing my RX-8 up. Hook me up....

 

There are plenty of cheap power gain systems on Ebay!

While you're there you can buy a flame proof suit 'cause you're gonna need it!
















None will work. Search is your friend.

 

First, welcome to the club.
Second, there is no cheap power. You bought a well engineered car and not a piece of garbage. Any car where replacing one piece (minus turbo systems which are factory detuned for emissions and longevity) yields significant power upgrades was not very well designed in the first place.

My personal suggestion is you develop a joy of reading. There is enough information on the site to rebuild this car from scratch. I can hand you a shovel, but I won't be the one doing the digging.

The cheapest HP/$$ for gains of more than 20 hp is nitrous. After that, you are looking at an FI setup or HEAVY n/a modifications. I don't see an NA Renesis ever putting down more than 220 at the wheels while still being driveable.

Nitrous -> Greddy Kit -> Pettit Kit -> Mazsport Kit

That's kind of a lineup mix of cost vs. HP vs. reliability of the most common kits these days.

 

lol....

 

Nitrous around something like ~$700+

Greddy Kit ~$4000

Those are your cheap options. Be glad I'm in a do-good-er mood.

Better thank everyone and start searching.

 

Thanks for the info, I'll look into the Nitrous Kit.

 

The greddy kit costs half as much as the pettit and makes more power and torque. far as I can see, your list is valid only on price.

 

I should have looked where I was posting... Lots of nice people.

 

Nitrous is cheaper and has a higher hp/$$ than Greddy. It is first. Reliability is highly debatable ranging from very to meh.

Greddy is higher hp/$$ than Pettit and is cheaper than Pettit, it is second.

Pettitt is cheaper than Mazsport. HP/$$ is debatable. It seems to be a very clean install. I put it 3rd.

Mazsport will make, at current, the most total HP, but is the most expensive. I would say the quality of the engineering of it is likely on par with Pettitt. I put it last.

My list makes sense to me. This was not a "greater than" list. It was merely a food chain/wallet type flow through.

 

Also, with luck Petite will well be releasing the high power version with 300+ hp and that should be faster then just about anything else. (Assuming the curve stays a similar shape, which it might not.)

 

heh. Nothing beats being a fan boi.

The limiting factor on the car isn't the amount of air that we can push in. The mazsport turbo should be able to give us 400 hp. We have other considerations to take into account.

 

I don't think I'm a fan boy of... well anything really.

I do like their curve. I guess I should have worded my post better. but I'm kinda tired right now (and damn hungry)

We already have 4 FI solutions that hit over 300 hp. (3 doing it well) And I think you said that the Greddy kit might hit 300 too with an upgraded turbo. So why would one expect Petite not to be the 6th one to do it?

What I especially like about the petite kit is the 2.5k to 4k range.

Even if I had the money to buy FI now I would wait and see. Cause nothing exists until you can buy it.

If I had to choose now between the Petite and the Greddy (With no option to upgrade either in the future) I would probably go Greddy. (Hopefully after a ride-a-long in cars equipped with each system)

(Anyways there is other stuff I want to do before going FI.)

 

Okay - fair enough. I don't think any of the RX-8 superchargers will be reaching the numbers the high end turbo kits can reach.


You can hit 300 with the stock kit, but it's pushing the turbo close to the edge. With an upgraded turbo (especially ball bearing), you can expect it to hit as high as any other turbo kit out there. Remember it's just a bunch of hollow metal tubes. The turbo is what counts.


It definitely has the most power till 4k, where the greddy leap frogs it. It will be interesting to see how the higher power SC graph looks. Actually, it would be nice to see a normal dyno graph of the pettit kit, since all we have so far is a small printout that was displayed in a window of the car, and someone took a photo of that.. errors could be compounded by enlarging it to fit a normal graph.

 

Interesting, may I ask why. I simply do not know much about FI, SC vs TC. Again thanks for taking the time (so many times now) to educate me.


Cool. I don't suppose anyone on the board did get a turbo upgrade for the greddy and dyno-ed it? (I'm off to hit the search button.)


Yeah, the 4k holds interest for me, because I am more often in that RPM range than I would like to be.

I didn't know that about the Petite graph. I'm very surprised they haven't posted a "real" one at this point. I would be very hesitant to spend that kind of money without a "real" graph.

Have you emailed Petite perhaps asking for a plot?

Again, Thanks a bundle!
