i was coming up a long straight street in my area of town when i spotted an older rx7 ahead of me i pulled up door to door with him and just sat their to see if he would go he suddenly jumped on it and i did to at about 35 40 mph i instantly started to pull got a car lenght on him assuming he knew he lost and had no chance i just let off he continued to go and did a fly by on me and i jumped on it again slowly pulled and got door to door with him again when we both had to start breaking for a red light at the light the guy yells at me yr car sounds like **** i just smiled waved and laughed as i made my right hand turn silly ricers will they ever learn

 

nice kill
the older RX-7s are kinda a slow car though
have one in our club only running high 17's low 18's
though he has a few problems

there strong point though is if you throw in a PP motor ( hold on need to take care of myself now), bridge port or heavy street port you might have to worry.

bit of advice
if it sounds like a chainsaw that is pulsing really fast... you might want to worry

 

rule of thumb.. if it's idling and sounds like a *blub* *blub* it's either got MAJOR problems or it's a ported Rotary that is probably making 300+ HP without a Turbo.

You probably raced a 1st gen (the 2nd gens look kinda like Dodge Daytonas). Either way, if it wasn't a built motor, or wasn't a Turbo, then it's not really a challenge.

 

for an LG4 the second gens might be a good race. stock for stock

 

Nice kill. We all know RX7s are slow.

 

Lets see: third gen rx-7 vs. third gen f-body.
stock horespower:tt rx-7 255, l98 255.
weight: tt rx-7 2750, f-body-3400.
rear end: tt rx-7 4.11, f body 3.23.
tranny: tt rx-7 5 speed manual, l98-4 speed auto
This is all stock for stock you decide who is faster.

 

mmm....
with the numbers you are giving me it kinda looks like the l98 is going to win


but you know those third gen rx-7 are a pain in the but to me

would love to own one. they are fast as hell and stock R1 can pull the same handling numbers as a NEW z06 vette

 

i raced a 94 0r 95 rx-7 with a turbo from about 30-40mph and i barely took it, that was a quick little car, although no one will believe me b/c they all think that rx-7s are "too fast for my iroc to beat" well i know what i saw oh by the way 86 IROC 305 TPI crane compu cam, edelbrock headers (not installed at the time) hooker super comp cat back, K&N airfilters, B&M Megashifter and a little porting of the plenum along with some removed air restricting peices ? what do you guys think?

 

Are you sure it was one of the turbo ones? Are you sure he was racing? What rear gears are you running? TT 3rd gen rx-7's run mid 13's stock with a good driver.

 

RX7's are pretty cool, but don't impress me too much. A friend dropped 3 grand [or thereabouts] for a new engine, larger turbo [boost controller too] and some intake work, with a downpipe. Had some various other stuff that i can't recall, and some electronic thing where he could actually manage the car's mixture based on throttle setting, and rpm's.

Dynoed it last Thursday, had 204 rwhp, and 153 ft-lbs torque. It's a 1991 RX7 Turbo II.
V8's though, can't go wrong with a $100 camshaft and gaining 85 hp

 

your friend must not know how to tune these things then
the stock turbo on the car doesn't have the best of flow and stock the car puts out 200hp at the flywheel and I think close to 180-200 lbs/ft again at the flywheel. so something is wrong there cause he is dropping quite a bit of torque.
the intake on the cars suck stock also and you can get quite a gain just by doing some work there. and the cat setup on the exhaust my *** it would be like trying to take a nice fart of your after eating a **** load of beans and trying to fart through a straw with cotton stuck in there.

just by the exhaust and intake work alone without using a boost controller to up the boost he should be making I am guessing around 220-240 at the flywheel which is about 187-204 at the wheels. again that is just intake (not just a filter but a turbo inlet duct that cost about 5 bucks to make from home depot) and exhaust.

then a bigger turbo can gain him quite a bit from there. I would say an extra 50-300hp at the wheels can be gained from a turbo that is not going overboard into the full drag setup
a boost controller you say well then that should be able to gain him a lot of power if things are set up right

and what sounds like a S-afc which yes allows you to controll the fuel settings should be able to net him about another 5-25hp at the wheels depending on his current mods

mods make power right? not lose it

not trying to be an *** or anything but your friend should be pulling a lot more power then that

**** have a friend here in the rx-7 club
all he has is a gutted cat, filter, and a turbo inlet duct ( the pipe that connects the turbo to the filter), boost controller set at 12 psi and he took his car from a 15 second car to a low 14 high 13 with a good launch

also one thing with the rotary motor is how much of the rpm range they can make power. most stock turbo cars make within 15% of there max torque from 1500rpms all the way up to 7000 rpms. real nice to have a flat power curve then one that only gives you power for 500 rpms or else you will be out of your powerband most the time....

can't beat a turbo $5 50-100hp

 

Yea I know, he was pretty pissed, to see that much hp after 8 pulls on the dyno (it was 94* outside too, so that might be a small factor, heh). Last time he went, he got a rwhp number somewhere in 180's with the exact same mods minus the aftermarket turbo. We couldn't figure out what was going wrong [like I know anything about modifying Wankels].

The car's exhaust did manage to melt 1/2 way through 2 of the straps holding down the car though!!

Was my first trip to the dyno ever, so that was interesting, you have no idea how loud that car was in that room, when he hit roughly 4k rpm, the exhaust would almost be loud enough to make your ears bleed, and then the boost would kick in, such an eerie sound. Fun stuff though

 

nice kill




its better to then to fade away!!!!
