I am posing the question to see what is the minimum rwhp FD that has run in the 11's. I dynoed my car 2 weeks ago and it only make 293 to the wheels. With proper tuning I know the car can make between 340 and 375 at the wheels.

The best I have been able to run is an 12.5 et with my current horsepower. My car weighs around 3025 with me driving.

I am wanting to know how much power I am going to have to make to run 11's.

Tell me your thoughts and or experiences!!!

I have talked to others with about 350 rwhp that ran 11.8

kwikrx7

I saw someone with 337 rwhp run 12.1 and someone with 354 rwhp run 11.7 - depends on driver but I think the 350 rwhp with DRs will get you 11s

I can't give you horsepower numbers as teh car hasn't been dyno'd on it's current setup but I can give you a list of mods.

Spoolin93R1 hit the track tonight and ran 7.88 in the 1/8, that translates to a high 11. It's all really in the launch, the car made a 1.7 60' w/ nitto drag radials on stock wheels.

The mods:
Atkins streetport
Apex'i FMIC
Apex'i PFC
Apex'i GT spec exhaust
Apex'i intake

A few more little things, but this was also done on blown turbos creeping to 14 psi then falling off. The car is also untuned, only runing a basemap.

Actually looking at your sig you two have very similiar set-ups, sounds like a streetport would get you there.

12.5 with 293 hp seems really good. From what I was looking at, I thought I needed like 330-340 rwhp for low 12's. I guess I was wrong. But thats good news for me.

Thanks for the input so far...

I don't want a street port at this time. Once the car is tuned I want it to run only as lean as needed to hit 11's. I want this motor to last.

My best 1/8th mile thus far has been 7.98.

I have no problems with my lauches. I can turn 1.7 60's all day long.

Another questions...at what rwhp should I start worrying about the rear end of the car?

360-370whp will get you into the 11s w/ some good driving.

You have to realize that there are a lot more factors than just power that determine your ET. Traction, skill, the track, conditions at the time of the run, etc. all factor in. You'd be amazed what some sticky tires and a cool night can do for times.

That being said I think ~360 is a good estimate for an FD, for high 11s..

Thanks...I realize all the factors that contribute to running 11's. I was most interested in seeing who has run in the 11's with the least amount of rwhp.

cow

Alright.. as long as you know. I'm used to uneducated people saying "how much hp do i need to run X" (or beat X) and it gets old. Maybe you should have said that in the original thread. :P

i trapped 114.5 mph on a very hot day with 14psi of boost. My car made 340 rwhp @ 14psi. That mph is good enough for a very high 11 second pass with a great launch.

LUPE

You only need around 112 mpm to make in the 11's with a RX7.

fastcarfreak

yeah, maybe with slicks and a 1.5x 60' time...assuming you mean mph


i think 112 mpm trap speed would prolly put you in the 1s, lol

LUPE

haha......... That's what I meant.........

400whp to run an 11 if youre real good.
400whp is the limit of the stock twins(and some)
350whp is the limit of the fuel system
350whp is about the limit of the stock clutch(mine anyways)
11's and 450hp are standards for single 7's, 20b's, and LS1's

blah blah blah

Yeah right............ Boostn7 ran 10.90 with 400whp.

Wow...I wanna know what traction/mods these guys have done...Thats crazy...

matty

330 rwhp amd et streets or drag radials is all u need to get 11s

sdminus

I ran 12.62 @113mph with stock fuel system and crap road tires and the original rear end and bushes. Also stock boost.
Car was stock port stock turbo with average bolt ons running apexi power fc basemap. Also had boot full of tools
