Somehow all of the WS6 owners I have met seem to think they can take corners better than my fd, then we race and they eat their own ****.
IMO drag racing doesnt take nearly as much skill as actual street racing/drifting, However I do lots of respect to people who do that, and everyone has their on thing, mine just isnt dragging.
First modification I'm doing to my FD is full suspension overhaul, I gotta learn my car in and out before I start suping up the HP.
mind you I've been going on back roads w/ my fd/my old 1977 MGB for about 4 years, plus its a hell of alot more fun, I pwned a 1992 Mustang on a downhill race(on the appalachians), in my 85HP MGB, that mustang is a boat for cornering, but will beat nearly every other modified car on a drag.
Cornering is the main reason I bought my FD, go try and take on that FD driver on a windy road, it'll be interesting.
AND RX7's are ANYTHING but rice, they are the higher end of Japanese Imports, when they first came out they were 30k+, RX7's are the exotics of the Imports, so plz dont call them rice.

Nice kill. If the RX-7 had run another pound of boost it would have been REALLY close. He probably does weight 27xx without driver but 26xx starts getting pretty hard without major dollars and without losing functionality and comfort.

i love the looks and comments i get regarding that.good kill... the LS1 is something that i dont take lightly... it could go either way. if the 7 had alittle more boost the outcome wouldve been quite different.
03 Cobras are just plain scary.... you can get mega-power out of those things with pocket change.... and they handle pretty good from what i hear. i hate it. lol. and yes... theyre fat, but dont underestimate them.

OK, ok, 7s are exotic rice. 
Better than a civic with a **** and fart can. They are nice cars and I do have respect for their individualtity. Any boosted up RX7 can go up against a stock LS1 and win. But if you get one that's well modded up.....well they're hard to beat.
Every car has there own sounds and feel. Some like the feel of a turbo or supercharger spooling up and laying them in their seat. I think that's cool. But there's nothing like raw Hp and Tq from a 5.7L (or higher) V8.

Try looking through the kills section. There has been plenty of Rx7's that have killed modded vettes and f-bodys. 
I have to agree with you here though. If I had to choose between a nice high hp N/A car over a turbo/supercharged car, i'd prlly go with raw hp.
There's a pretty slim chance that his car is much under 2,800 pounds. He'd have to strip the WHOLE car.
Where at in Tx are you? I'll be down there in a couple months, maybe you'd be up for a friendly race?!

she made 340rwhp @ 1.00 boost (14.22psi) as measured by the power fc. It ran 116mph traps. This was with a kdr tune and an 11.2 afr. I now had a hks ignition and upgraded my clutch and flywheel. Steve kan will be tuning it to 17psi. Stay tuned. Perhaps i will eat my own words although my arguement was always based on 15psi.

I live in SE TX. 99.9% of civics are fart canned mo fo's.....HOWEVER! I have seen some civics, and similar cars, That were highly modified and very light weight, running amazing times. So that is true, but come on, how many mid 11 civics do you see at your local stop light???
An LS1 speed shop once put a decent sized single turbo on a totally stock LS1 engine that had quite a few mile on it, at about 12 pounds of boost. It was in a Firebird Formula. The only mod was upgrading the valve springs, and they tuned the pcm. The car made over 700rwhp and almost 800rwtq. In the mean time they were building an all forged bottom end stroker that could hold a lot of boost. They were just seeing how long the stock engine would hold up. I was surprised that they put a ton of run on it at the track and like 50 pulls or more on the dyno.
Moral of the story, just be glad f-bodys and vettes didn't come with a turbo from the factory like you guys.

Wow, the stock fuel system and injectors flow enough fuel for 700hp to the wheels? Sounds like a tall tale in my opinion, it has all the tells of one, big round numbers ending in 00 and so on. I'd probably run away from that shop in a hurry as well because they're clearly full of crap.

BS! I'm with Kevin on this one, this is definitly a tall tale. Hopefully LT1-7 can chime in. He actually builds single/twin turbo kits for the f-bodys. The most that i've seen on a stock bottom end was ~600rwhp, but that was with an upgraded fuel system and so on. With that kind of power on a stock block, it wasn't going to last very long. I'm pretty sure there has been higher numbers, but certainly not with the stock injectors. With numbers of ~700rwhp, he'd need more than just tuning of the stock PCM.

Those 11 sec drag strip Civics will get beat by 12 sec rear wheel drive cars stop light to stop light. The LT-1 through LS-6 are light, compact, powerful and reliable motors. I never thought pushrod technology could go so far. The last generation body style Camaros and Firebirds have been looked past sometimes because of old technology (live rear axle and heavy) but they actually handle and break well too. They have been the best bang for the buck for a long time and it's too bad GM stopped production. Maybe they will be back with the late '60s retro Camaro look with an LS-6. That would be sweet!

I promise I'm not BSing. Now yea, I left out that they up graded the fuel system, and yea they put an alchoel kit on it. After they install the turbo setup, they started other mods like transmission, suspension, rearend. Basiclly they were seeing how much and how long the used LS1 engine would last before it blew, because they were building a forged motor for it. This was a year and half ago. They took all the pics off there site.

ws6, I wish you luck with your car, but remember all 7's are not built the same. The funny part about the 7 is that a mildly modified one looks and pretty much sounds just like a street single turbo 7 when the hood is shut. I've humbled countless american cars with my single turbo rx7, so keep your ego in check when you deal with a turbo car you don't know alot about.
