I was driving to a friends house one night, and I stop at a light to see the lights of a CLS behind me. I could tell he had intake, exhaust and what not done to his car. So his boys in the car start looking my way, and I look to the driver, and I say "that's a good looking car". I love how the CLS' look but he grins and revs his car. NOW he wants to race me? My car weighs in a 27ish, the CLS is like 3000+, plus he had subs in the trunk, and two other passengers. I have a quarter tank of gas, and no radio in my car. His friend asks me how much hp I have, I respond 260ish. They all don't realize my RX7 is a turbocharged 260hp, plus it is a rotary so my torqueband is immediate, unlike the CLS that have 260hp at like 7000rpm. Plus my power to weight ratio is much better than his! So we start rolling together at 15 mph and we run, and I beat him by like 6 car lengths. After we ran, we got to another traffic light, and he didnt even stop next to me. I guess the sound of the turbo, and the flames shooting out the exhaust when I let off the throttle must have scared him.
1.3 LITERS OF MADNESS!!!!!!!!!!!!!

good kill Gotta love that rotary power

Mike

nice kill. what do you run in the 1/4? guy was a fool to race you with all that extra weight

typeR

ya whats your track times...

typeR

BTW his car would have been 4000lbs with passengers ...3500+/- empty

CLS2001_97124

Damn.. the guy is a dumbass.. wtf was he thinking tring to run a RX7 with all that extra weight.. plus even if he was by himself, I would still be a little iffy on running against a RX7.

Pappy

That shows you how important the power to weight ratio is.

Black CL-S 4-Life

Nice kill!

A stock 1990 rx-7 turbo 2 does 0-60 in 6.3 ,1/4 Mile 14.9...and you say 6 car lengths? Is your car stock? /if so they had to be some real fat dudes with a heavy ass stereo.

scalbert

Not to mention it was 200 HP stock. But some engine work can help boost the power.

The torqueband comments are unusual though as most rotaries need revs to make power...

numbaonestunna

I don't think so... 200HP with the turbo? Plus, you have to understand that rotary engine is much more efficient than psuhrod or overhead cam... don't have to waste energy converting linear to rotational motion

scalbert

Engine: 13b rotary turbo
Horsepower: 200 bhp
Torque: 200 lb-ft

Granted, there is a relationship to rotational loss, but a piston driven engine (which is what I believe you were hunting for) does allow for leverage to help in torque.

A rotary requires higher RPM to make it optimal power. The efficiency comes at higher revs. But coming from someone who cannot discern the difference between HP and Torque, this confision is not surprising.

You might be confusing the 3rd Gen output which was closer to 250 HP. The stock 2nd Gen Turbo II output was limited to 200 HP in stock form.

sup guys,
my car is 200hp baseline, but with my exhaust alone it adds 60hp, and that's no bullsh*t. Check out racingbeat.com, they are pretty much the comptech/mugen for rotaries. Plus my intake adds about 12hp. Plus I have an HKS F-CON (piggy-back fuel system), Nippon Denso fuel pump, and some gauges. That is pretty much BPU for an RX-7. No serious motor work has been done yet, the only speed parts I have are intake and exhaust.

60 HP FOR A EXHAUST ???!!! YOU GOTTA BE KIDDING ME

typeR

hey thats the same thing they say about 30 HP for our headers...

JHEIII850Turbo

Man, on a Turbo the big bottleneck is usually an exhaust, open that up to a good 2.5 or 3" you can add some serious HP

zeroday

Very interesting. I'd love to see a dyno for your car. I'm looking for a daily driver with some 'teeth', so if what you're saying is true I'd consider buying one. My CLS is leased and my commute is killing me on mileage. I am aware that on certain cars an intake and exhuast can add significant power..but 60 hp seems like alot..Post a dyno!!!

fuck...i'm shopping for a 1987-91 turbo 2! :



1987-91 TURBO II Complete High Performance Exhaust System*

This is the ultimate exhaust for any Turbo II RX-7! Let your turbo breathe to it’s full potential with our “turbo-back” complete exhaust system.

The Turbo II High Performance Exhaust system incorporates a 3.15-inch (80mm) down pipe from the turbo outlet that mates to a presilencer section. From the head of the Y-pipe two 2.125-inch pipes extend to the ceramic wool-packed 409-stainless steel rear main mufflers. The bolt-on exhaust system increases horsepower approximately 32% - a 59 HP increase on a 1987 Turbo II RX-7!

The Turbo II High Performance Exhaust system reduces exhaust gas back pressure significantly, thereby allowing the un-assisted turbo boost pressure to increase to 10-11 psi. Our Fuel Cut Controller (part No. 11570 or 11571) is required to prevent fuel cutoff to the rear rotor above the factory pre-set limit.

This bolt-on system uses the stock mounting points for ease of installation. Each system is supplied with all necessary mounting hardware and gaskets (does not include turbo outlet gasket). The down pipe section is provided with a position for the oxygen sensor.

We also offer individually the components comprising the Turbo II Complete High Performance Exhaust system for those individuals wishing to build custom exhaust systems for their specialized applications. (See the following items in the section menu.) Note: The components in this system are not interchangeable with any stock or other Racing Beat exhaust components.

*Legal in California only for racing vehicles which may never be used upon a highway.

Well, my rx7 is not really a daily driven car, i use my CL for that. The more you drive a car like that, the more you need to stay on top of your maintenance.

TWINTURBOFAN

Check out racingbeat.com, check out rx7.com the proof is all there.

I really dont see how your getting 60 h.p. off of a stock car, maybe if its built.

CL-S-3:16

I got 52 horses to the wheels on my 1st gen talon tsi with a 3 inch exhaust. I can post the dyno for all three runs including stock. I will post as soon as I get back to ATL on Friday. Does anyone know what RWHP our CL-S's get stock? I was thinking of dynoing but I want to have something to compare to.
Thanks

acura516

if you stay on top of your maintenance, and take care of fuel enrichment, you will acheive that hp. it seems unbelievable but it is a reality to owners of turbo rotaries.

acura516

I was in my cousin's CLS, and he raced my friends 3rd gen rx7, at first the CL stays with it for like a second then that secondary turbo starts boosting, and it was just over. My friend's rx7 ONLY has a 3 inch downpipe, and a nippon denso fuel pump. The CLS is a really nice luxury car, but it isn't built to run with a car like the rx7. I mean really the NSX has a hard enough time running with that car. In a '97 issue of sport compact car they called the 3rd rx7 the "NSX Killer".

I've raced a 3rd gen Rx7(friend) in my CLS before and won. I think it was more driver skill then the car but I still won. Let it be known that I do have a highly modded 3rd gen myself(415rwhp) so I know what they are capable of.

TWINTURBOFAN

true, what size turbo are you running in ur FD? I'm looking to rebuild my motor in the fall and upgrade to a 60-1. According to the folks at turbonetics it is capable of 350+ to the wheels, and combine that with slicks can put me into mid-high 11s, or low 12s. You think this is possible?

al9rr

I'm running a T78 on my car but might downsize to a GT35/40. Heard alot of good things about them. A 60-1 seems like a good choice but I would go with something slightly bigger like a 62-1. I can't decide whether to go GT35/40 or T62-1. It takes alot more then an upgraded turbo to get into the 11's. Check out this forum www.rx7club.com

This thread cracks me up.

Racing Beat can can get you there, without question, but I
see no clear indicactions of this in TWINTURBOFAN's posts.


Exhaust is a "big" improvement for the TII, but not 260whp.

acura516

the hp gained is not 260 at the wheels, it's at the crank.
