arrrgggg.

I hate it when you have a post typed up then you push submit and it gets lost.

the short of what I said was "yeah what Lesper said"

there is not much you can do to an RX-8 to make lots of power. it is one of the major downfalls of the car. without boosting the car there is really nothing that will put a smile on your face from ear to ear.

with that said, Turbo, Super charger, Nitrous.... they all will get the job done..... they all will also lower the reliability of the RENESIS. :/

the turbo and supercharger are also rather expensive for what you get. dont get me wrong 80 h.p. is a big differance, but it comes with the price tag. (some cars you can get that 80 h.p. for a quarter of the cost.)

most bang for the buck is always going to be Nitrous. you can get that same 80 h.p. for under $1000. the down fall is you have to make sure you have the tank full, and have it on when you want to use it.... its not "ALWAYS there" like a turbo.


does this help any?

So Cesar what are your thoughts, Oh and Hi to everyone, Jedi, Speeddemon and the rest.

See I thought about NOS but isnt that much more wear on the motor compaired to turno or SC?

Jesse you have hitman for 360? how is the game play like. i love the look of that game.

with all motors, there is power/mpg/pollution. increase one without decreasing the others will always result in more stress on the motor (longevity). the big concern with nitrous is that wet type systems may corrode certain parts of your motor. but charles r hill has proven many doubters wrong.

your best bet is to search keywords NOS, TURBO and SUPER CHARGER. there simply is too much information involved to be asked here. by the way, you may want to look up PORTING as well.

its cool....kinda a pain to figure out the controls

ya thats why i got the 350z i put every na mod u can think and got really no where. it got to the point i just got tired of me smoked by every other car on the road, but the rx8 is great in the canyon but i dont get up there as much so i need a car i can have more fun in normal driving. in my new 350z with new hr motor i rana 04 z06 up a freeway ramp we stayed side by side the whole way

speeddemon32

exactly....


Nitrous is not as dangerous as most people let out. (not that I am an expert at nitrous, but I have been around it a lot) the key is to do it right. there are a lot of people out there that have put nitrous on the "gheto way" and blown up the engine. you can do the same thing by ghetto rigging a tutbo on your car.

there are many things to remember when you upgrade your car. when you upgrade part "A" and produce more power. Parts B, C, D and E will become the new weakest link. upgrade B to produce more power, and C,D and E are even weaker in the link.

so for example, you install a dry nitrous kit.... lets say a 40 shot. ok you just added power but nothing insane. the stock computer will be able to adjust to the lean condition cused by the nitrous and add more fuel to compinsate.... not to big of a deal.

now lets say you take out the 40 shot jet and put in a 100 shot jet. the computer will try its hardest to compinsate for that extream lean condition but it cant, the engine will beguine to burn a hole through a rotor. (or piston).

so you want that 100 shot nitrous, you add the wet part of the system (added fuel) everything is gravy.

you decide you want 150 shot, you even up the fuel part of the nitrous system, well thats great and all but the weakest link of the chain here is your ignition system. you now are putting so much nitrous in the engine that the timming needs to be retarded a few degrees while under the squeeze or else you will have catostrophic failures. yo now need an ignition system like an MSD with built in nitrous retard........

the next level of upgrade and weakest link would become the engine, it just isnt built for the kind of nitrous levels. there are many internal mods that need to be done to hold those kinds of nitrous levels.

you get the hint.

the point of my story is that there are limits to what you can do. the same story above applies to turbos and super chargers. you dont see greddy selling just a turbo for the car right? they also included the emanage which adds fuel, and i am pretty sure it retards the timing. there are also other things that come in the kit to make it as safe as they can.

the biggest down fall of the RENESIS and a turbo or supercharger is that the commpression in the RENENSIS is just to high for boost. thats why you can only run 6 pounds or so and be somwhat safe. a "turbo built" engine will have much lower commpression capable of MUCH higher boost.

but even then, lets say you take a stock turbo ready engine, and try adding lots and lots of boost. well now you need to have the engine pinned, port increased, intake air temps lowered, exhaust opened up, entire fuel system upgraded.... blah blah blah.....

ok I think you get the hint. I know I am rambling on here.

the point of the story is as long as you do upgrades right you will be fine. but thats the key do them right.

if you are interested in nitrous, go with a medium shot wet kit, have it installed right, and it tuned, and it will last you for many years to come. also talk to that Charls hill guy. he knows what he is doing when it comes to putting nitrous on an RX-8.

If you want a supercharger, then go with the axil flow kit when it comes out. it will be a nice kit, and it will be compleate. but it wont be cheap.

you want to port the engine, have someone that has ported an RENESIS before do it. there are moderate gains to be made, but agtain it is costly.

there is an old saying, "speed cost money, how fast do you want to go"




now on the other hand, if you are not looking to spend so much money, you want to keep the mods to a more normal level. intake(dont know if you can find one for an auto) exhaust, pulleys, (you cant do flywheel as you have an auto), those mods are not nearly as expensive and you can do your self. but you also wont get major gains out of them..... on an RX-8, not even moderate gains.

also try to embrace what the RX-8 is accually good for. do some suspenssion mods. shocks, springs, sways, tires. those will go a long ways. you may not be upping the power, but it still makes the car more fun to drive. more so on the mountain roads.


sorry for rambling on and on. I even tried to keep it basic and short.

We had NOS on our Miata, 50 shot, it was great. The reason people have problems with it is greed. If one little hit off the crack pipe is good a big one must be better, so they bump up the jetting and have problems. The same thing can happen with a turbo or supercharger. If you get greedy and crank up the boost to much on the turbo or underdrive the supercharger to hard you will hurt stuff. Most times the damage comes from a lean condition, the stock fuel system can not keep up, second is to much pressure.

Which is harder on the motor.... Well once forced induction is installed it is on the car all the time. With NOS it is only putting stress on the motor when you use it. For the money hard to beat NOS. I know guys that did track days with it. A nice big bottle with a small shot, 40-50hp, will last a session if you only hit it on the strait.

A 50 shot on an RX8 should give a good conservative bump in power without a lot of added stress on the system. Also going with a conservative shot means the bottle will go longer before a refill.

That Z06 must not know how to drive. It pushes the peddle on the RIGHT or it gets the hose...

Prey is an awesome game .

i got it for my PC. it's also available for the 360 if you guys want to check it out .

The thing 350Z guys forget is along with that extra HP/TQ you got you picked up 350 lbs of dead weight over an RX8. The Z has it on the big end, but the front suspension and LSD suck, good thing is they can be fixed easy and then you have it all. Hard to fix the lack of power on the 8.

I have owned five Corvettes. You learn real quick you only need half the pedal to take care of most kids in ricer cars. Most of the time it is not worth the effort.

I will get FEAR before I get Prey, it looks a whole lot better.

Great write up Speed I understood about half of that.

man.. this talk about nitrous is getting me all gitty inside. i was originally gonna port my motor and get new wheels for march-april. but since dave past away, i started to look into a nice wet system + 18x9.5 wheels. you can make a pretty good system for about $300 and just like seeddemon and ulllose said, its almost perfect for the casual budget tracker.

but i ended up buying something else.

kwescott

Jordanjerome.....one of the guys who has been modding his AT 8 the longest is Mikeb. He has like a million or so posts, has been on the board a long time, and has tried many parts for his AT. He can give you a great list of parts that didn't work, and have worked for him. I would suggest pm'ing him...as most people with AT don't end up doing much with their cars. ZooTender also has an AT, but hasn't done any performance mods.

I would agree with most, that your throwing money away, especially in trying to upgrade HP on an AT. Spend the money on suspension or lightweight wheels with good rubber. Much better use of your money.

speeddemon32

yeah, I have a NOS nitrous kit sitting in my garage. I have not put it on mostly due to the auto cross. :/

I agree 100% with what ULLOSE said. thats pretty much what I was getting at in my novel above. if you stick with something like a 40 or 50 shot, you will feel a differance, and still be safe. you want to go faster and it will cost you. (in either the bigger better nitrous setup, or turbo, or super charger, or porting, or.... or..... or.... )

peterisurhero

i want that 55 hp wet shot too! haha i am planning on getting it soon

peterisurhero

hey keith and casey, i juss talked to dpe and he said he will ship the parts out to me later today. So when i get the parts, i will let you guys know and then i can just wait for you guys to have an open weekend etc. let me know guys.

kwescott

Jordan, all this talk about NOS...I have to provide you my feedback. I was able to drive next to an RX8 with a ZEX 40 shot....no big deal man. I wouldn't do it. More hassle than what's it worth IMO. (my 2 cents).

But then again, this is coming from someone who threw a lot of money at the 8, for no real HP gains either...

It's more than just HP....come out to an autocross and you'll see exactly what I mean. Ulllose has bairly anything done to his car and he'll woop on any RX8 out there, as well as some other cars with more HP.

Talk to Ghost or I about the RX8 we saw at the Streets of Willow. Stock RX8, was stomping on Evos all day long. It's not all about the HP.
