i know of a second gen rx7 that a little over 200whp on a streetport. what have u guys seen?

 

also i read that pinnapple racing made 260 on a streetport. do anyone think this is true?

 

wat kind of mods do u need to run 200whp on na?
is it better to rebuild a na motor or to swap a turbo engine in?

 

search for BEEFY N/A

 

i also heard of some guy on the rx8 club making 228rwhp on a rx8. even though its a renesis, its still a 13b just with a little higher compression and a bigger streetport. it also has a stricker exhaust port so why shouldnt any other 13b make that kind of power?

 

the peripheral ports on the renesis do most of the power but when you do a PP on the DEI 13B you won't get the streetability of the RX8

 

Ummm, the renesis doesn't have ANY peripheral ports, not even the exhaust.

Also, I call BS on 260 hp from a street port, unless the ran N2O as well.

 

i read this at pinnapple racing. that was there claim, (260hp at the crank). i dont see how its impossible if the the renesis can do it.

 

Ask this guy!

^^^ That's bridgeported though... whole different monster.

 

My bad..... didnt see the street-port part.

 

260 at the crank is different than 260 at the wheels.

I was originially aiming for 250 at the wheels for my setup, but I figured a semi-pp would probably be better for the money that I was going to spend. My orginal goal was to have the highest hp in an NA non-bridge/peri 2 rotor engine RX-7 in an FR layout.

 

were u originally aiming for 250hp on a streetport?

 

yup.....but you don't want to know how much money was going in to achieve that.

It takes about 5k to get 90% of the way, and another 10k to get that last 10%.

 

What were you planning in order to get 250 rwhp?

 

where are you at now?

 

I'm at 170 whp on a stock NA engine.

You guys really don't want to know the money or steps involved to get to 250 whp......plus I don't feel like giving my idea away just yet. =P

 

where would 15k go to?

 

The idea is simple:

Start with the best block for making NA power

Maximize the efficiency of:

Intake
Exhaust
Port Work
Airflow
Combustion
etc....

Minimize power robbing aspects of the engine

Finally, proper standalone and an aggressive fuel and timing tune.

Basics that should be pretty much followed anytime you do a mod, it's the part and modification choices that make the potential.

 

im assuming half of that money is gonna b in labor right?

 

nope....parts

only labor would be porting.

 

ok now that iv read above, do u think 250rwhp is possible from a streetport

 

it's possible, but you could hit much higher power levels with that much money and a turbo swap...i.e. hp/$ goes downhill after 200 whp

For example, it'll take about $5k to get to 200 whp, and another $10k to get 50 whp....50/10000 =.005 hp per $ spent.

 

thats about 280hp at the crank. have u seen it done b4

 

nope, i would be the first to attempt it, just because to get to that point, you'd have to be willing to throw away bang for the buck power and just concentrate on being unique.
