Okay, so I put in a K&N Filter. Of course this only icreases HP in the upper revs where the engine is breathing heavy.

Anyone know of a good way to increase low end power that won't break my budget? I'd love to super charge the Renesis, but not until this sucker is paid off.

Don't even suggest one of those "electric super chargers", They might increase boost by a a psi, not 13 like you need.

 

acutally, the K&N doesn't increase HP at all. There's NO way to cheaply add HP. If you want Cheap Additional HP in your car, get a different car.

 

did you mean knn typhoon intake or just a drop in filter?

 

Add more boost juice!

 

Midpipe is probably the cheapest hp/$ gain. After that nitrous. Nothing else will add more than a few hp for much $. Unless you go to a Canzoomer piggyback unit which is not exactly cheap. Even then you are looking at more hp gain & less tq. Unless you do a turbo or nitrous there is no other product that will give you any noticeable grunt on the low & mid range.

 

I was thinking NO2....

But what does this do to the engine in terms of wear and tear, and how does it affect the warranty?

Performance chips sound useful, but I assume there's no basic diffenrence with the chip, you need the chip plus more air and free flow exhaust to get any benefit from chips.

Does a programmable setup seem reasonable? Esp if I expect to make incremental changes over time, as budget allows?

 

Just the drop in. I'm considering the Typhoon.

 

Nitrogen dioxide? That'd be unique - I bet you'd be a pioneer of sorts. Just a warning, NO2 is a pollutant, and if you have asthma, you could really hurt yourself. It's also corrosive.

 

There are none - sell the car and get a Civic. You can mod it to your hearts' delight. The RX8 doesn't take well to many performance mods...mainly intakes and exhausts. They may sound different but do diddly squat for performance.

 

They make a CryO2 system that uses CO2 to cool the intake, intercooler, radiator, oil coolers, ect... They claim to increase HP a good bit. I've seen it on a turbo eclipse and I plan on using it once I get my turbo on. The system is not suppost to harm anything in the engine either.

The Midpipe is just about the only mod that is reasonably price mod that gives you HP that you can feel. Mine has alot more pick up with a custom 3" exhaust than it did before, only cost about $90 too.

 

It will increase the stress on your engine a bit, but then again everything that is FI will. It is pushing in more air or causing larger reaction then it normally does causing larger combustion, thereby putting more stress on the engine, causing more wear & tear. Nothing is free in this world. Pretty much all of it will void your warranty. With turbos & SC's it would be a bear if you blow your engine & need to take it off before you bring it in. For Nitrous they can detect residue in your engine. There are quite a few of the people on this board running 55 shot of nitrous along with other mods, like Charles R. Hill, Addictive RX, etc.

Most of the people who got the piggyback ECU (what you call the "chip") usually have the other mods air intake, midpipe, exhaust. Gains have been variable from 16 to 25 whp. It definitely needs to be tuned if you get it.

BTW, the K&N typhoon is junk. Widely proven to LOSE you hp. If you are going to get an intake, go for the Racing Beat REVi.

 

no $/horsepower gain like the turbo.

$3000 for 60 whp (usually 180-->240 on the dyno with exhaust, GReddy claims 238-->303).

 

True about the turbo. It's the way to go. Cant wait till mine gets here. :D

 

huh?

Turbo: $3000/60HP=50$/HP

piggyback (used): $400/15HP = 27$/HP

piggyback + ability to tune (both used) $500/25HP = 20$/HP

 

The K&N drop in may add 1/2HP or 1HP in the RX8--it is still a good buy because it slightly increases gas mileage and it pays for itself since its reuseable. Racing Beat intake coupled with a catback will get you 5-10whp--(closer to 5hp)--those will not void your warranty.

 

ok--we'll intake and exhaust are not 'supposed' to void your warranty. I already talked to my service advisors about it.

 

I've heard the KN Filters lower HP. I think they have a new one coming out. I'm going with the Racing Beat REVi Air Intake. But its around 300 I think.

 

To funny, ROFL. :D :D :D

 

took the words out of my mouth

 

You're making a lot of assumptions there. I have seen anywhere from 15 to 25 whp from the CZ, but only with other mods. It was not just 25 whp with the piggyback only. Also, even with dynoes showing around 20 whp gain, they gained like 4 ft.-lb. of tq. The turbo puts out 60 hp, but also about 60 ft.-lbs. of tq. as well. The origianl poster wants low & mid range acceleration. The CZ unit is more for top end improvement. Also let's compare apples to apples. new vs. new, not new vs. used.

 

The typhoon intake does--not the drop in filter

 

This is very accurate to what I have found with the Canzoomer. Don’t get me wrong, I love the Canzoomer. The gain is all at the top end when tuned properly and with the replacement cat - a great deal of fun, but not the same as forced induction.

 

i got 25rwhp increase and my car is st0ck except the CZ...

 

I guess I wasn't addressing the intent of the orginal post. I was addressing only one thing - the assertion that the turbo is the most $/HP available. It clearly is not. The turbos aren't available used yet so you can't compare those. I simply compared the available prices on each. And, I didn't include the cost of boost gages. I guess you need those...

Even new, the CZ + CanScan is about $31/HP. New CZ alone gives you 40$/HP - both still lower than the turbo.

High-end HP is certainly more valuable and worth every penny if you want to track the car. I just got back from the track and I never got below 6kRPM anyway.

 

I wonder how much the RX-8 would weigh if you "trimmed" off the entire rear cabin and converted it into a two seater with a trunk.
