ok can you SC(supercharge) a na rx-7
 

i have been doing a lil reading and very curious can you SC a N/A rx-7 and what are the results and is it better than turborcharging?

You can supercharge anything, with money. Immediate boost is one benefit of being supercharged rather than turbo.

ok is it wasier...because i know to turbo a NA engine takes a LOT of fabrication....so with the high compression of a NA motor is it easier and better to do??

Search, its been done before.
Ups. No turbo lag, easier to pass emissions b/c there's nothing blocking the path between the engine and the catalytic converter(s). No need for BOV (in most situations)
Downs. More for the eccentric sharft to spin. Mostly mid-range power no high end. Placement can be difficult if you have all your AC, PS and emissions etc.

The rotary engine likes the turbo. :D

If you do any kind of forced induction wrong kiss your engine goodbye.

S/c and Turboing an NA take about the same amount of HARD WORK :rolleyes:

Doing anything to an NA engine = fabrication.. turbo, SC.. dun really matter... even with the 3k+ Camden kit i think you still have to do some drillin and shit.. correct me if I'm wrong boys...

I want to finish my SC project, but just don't have cash atm.

ok so what kindaof performance can you coaxs out of a NA?

whatever your tuning abilities are

Yeah, it's all up to what you want. You can get a Peripheral Port N/A pushing out, what? 350HP IIRC? But that's strictly for racing applications, not street.

BTW, search is your friend... and spell check too.

ok can you suggest any good web sites to look at for tuning a NA

IMHO your are already at the best website to find information JUST USE THE SEARCH FEATURE !!!

rx7club knows about everything

I don't think anyone has made the note yet. For the power:money ratio...turbo is all out better than supercharging for these cars. Most 3,000 dollar supercharger its, custom or not, will net something like..250 RWHP.

^ which can be done for like a grand on a Turbo II if you get some good deals

may be ok to pass emissions in some states but in california and many other states it is an illegal mod and will fail the visual inspection.

Turbo lag? A centrifical blower on an RX-7 (IE Paxton) doesn't start making good power until 4,000 RPM.

Placement is relatively simple, check out IntegraLS, just relocate the throttle body and place it where the AC and PS was. Since pussies use AC and PSing anyways :eek: .

And yes the Rotary engine does like the turbo made from all the fun exhaust gases we push out.

Also it has be PROVEN TIME AND TIME AGAIN that forced induction on an NA is just fine IF IT IS TUNED CORRECTLY. I hate when people tell others that. Sonik, Aaron Cake, Integra and ALL proving that wrong.

Wasn't talking about centrifical, fuck those, i'm talking a big honking whipple blower!!!!! Yeah i know we can do forced induction on NA i have half the part to turbo mine,, I said if you do any kind of forced induction WRONG kiss your engine goodbye, read the whole sentence man. :rolleyes: :eek: :D :cool:

Sorry, if I could read minds, I'de be a millionaire ;).


Stating that doing anything wrong with your engine will blow it is just common sense. I thought you meant more in your statement instead of just stating a basic fact. Either way I don't care :jerkit: ,

Neither are easy. The most simple path to a fast RX7 is start with the right car: a TII.

Ain't that the truth.

first of all.....you can TUrbo an NA by doing an engine swap.......that's the EASIEST way to get more power.

a guy on here SC'ed his vert and only got 187rwhp (37 hp more than my fiancee's NA dynoed to the wheels) which seems like a waste of cash........you can turbo the NA motor but again you will need to fabricate a lot of crap for the FC......


the MOST you can push in an NA without porting the motor is anywhere between 150-160 rwhp......

CodeBlue has thousands into her car for 209HP.

If can, find an old Paxton or go Whipple.

those thousands would have yielded more HP if she had done a full TII swap and MODDED the car........wouldn't you agree?

Damn shame too, if only she knew in advance how much worse a straight two lobe rotor based roots blower is compared to the Eaton M90, which itself isn't spectacular.

The only way to compete with the power and efficiency of turbos is to pick a belt driven compressor with near the same efficiency (ie. how much more heat the charger puts into the compressed air than it would have had if based on the ideal gas law).

Oh well. At least she has 209 rwhp, which should be kind of fun.

88 how much do you expect to get out of your setup?

Isn't boost, boost?
Whether it's from a turbo or an SC? The only major difference is what RPM it starts at. So wouldn't SCing an N/A or turboing an N/A other than fabing parts be equally hard on the motor?
