Non Turbo 200whp feat

200 to the wheels is a pretty reachable goal for an s4 na. first of all make sure everything is working properly first. you could do methanol injection, mild streetport, and t2 secondaries. go stand alone or rtec 2.0 and i would be surprised if you got less than 190 to the wheels. yo could also throw in a lightened flywheel, and a t2 transmission. this is all assuming you have a engine with good compression. it would be your call if you wanted to tune your car with the methanal or not. even without methanol. my buddy put down 184 to the wheels and all he has is rebuilt injectors, and full racing beat exhaust, and rtec 2.0
It's very hard to make the 200 on stock manifold, stock ecu, even in an S5. Highest was Kahren's 195 whp run. A little more doable if you can go aftermarket on either of the two mentioned before.

from Grassroots Motorsports Magazine - July/August 1995
Article title "Mazda Project RX-7 pg. 49
"Our completed four port 13B features street porting and programmable electronic fuel injection, and makes over 200HP in street trim."
The engine was built by Petit Racing and uses 2 TWM40 mm throttle bodies and a Haltec F3 ECU. They also show photos of the ports that Petit used.

Do you have a GXL or some other car with the trim level GLX?

AC/Air pump (assuming AC is off and freewheeling) is like 2-3hp draw... I'm not worried about that. The REAL benefit of removing them is weight loss... Secondary benefit is de cluttering the engine bay.

my engine bay looked so basic and easy to work on. I eliminated everything and didnt look back. If something was wrong with my car, I was able to figure it out and fix it with no problem.

The power steering is the only thing that really puts any REAL load on the system... Throw in a manual rack... if you aren't in a parking lot, you almost never notice.

I promise, you will see along with every other person who doughts me. Just because im new to this forum doesnt mean that i dont know ****. Ive been doing my own work every since i brought my car 3 years ago including rebuilding the engine, unlike half the people who talk **** about what can and cant be done and probably never touched a wrench before. Like I said I promise you will see.
Oh yeah, I hope i get the noob of the month award.

O.K. forgive me for skipping some posts, but I didn't see it discussed. I have a question, which is not extremely related, but this thread has a good audience who will know.
Not looking for 200whp here - but will an RTEK help me get the most out of a streetport, everything else being the same, including injectors, factory intake setup including AFM, but aftermarket headder and exhaust? A stand-alone is too much for my budget.

In reading through the articles, they did not say whether the HP rating was flywheel or rear wheel, but that should be remedied in a few months. It will go on the dyno in a chassis. I am impressed with the size of the ports but am puzzled by the finish of the insides of them.....should do some more research on those.
At the time, the throttle bodies weren't all that expensive. I guess they are a bit more expensive now. The article quoted them at $240 each, the fuel rail at $130, and an ITG air filter system with air horns for $220. They mounted them on a Weber manifold.
Another thing I have considered is trying a couple of the Mikuni PH44's on this engine. I have a triple setup for the Z sitting on the shelf. It would be interesting to see what the difference would be. All in due time............

so your saying a stock 5.0 is extremly fast you think your ******* s5 is so fast race a 5.0 mustang on NOS it would be equivilent to a turbo ll so race it and see how it terns out let me know how it terns out.i'd say most of it depends on tuning. and how large of a streetport you go with

twn does nothing better then a stock tb from an fc, 3 smaller throttle bodies are the same as 2 bigger ones. i woudl rather have 3 throttle bodies as they can be split up better between the ports on a rotary. so really you are paying money for nothing, the thing thats not so good on the other hand is the stock intake manifold, thats where twn gain mor epower, not because of the tb, but beacuse you of the better manifolds bolted to the engine when using the twm or something of that sort
why people think an aftermaket thorttle body will add more power is beyond my comprehension
