Mid-High 11's with a flawless driver, there are too many factors that come into play to tell you exactly what the car would run.......high 11's is a guess given by the calculator at rx7.com

ive seen 420whp RX-7's go 10's.... an FD with 350whp and a flawless run should go 11's@117+mph.....this is assuming the car is making boost quick and being driven well with traction.....

Heres one for our 1/4 mile table

Should give you a good idea HTH


Does this forum have something similar, showing 1/4 tables or dyno results?

YOU will be in the low 12's. try not to populate the forum with this trivial crap. If you want to know your time go to the strip.

Aww come on dont be a party pooper now. I've seen BoostN7 with his 402wrhp on stock non-seq twins make a 11.00 flat run.

And dont forget, its not just about the motor, its about the entire setup.

I posted a vid here (not sure if it's still working): https://www.rx7club.com/time-slips-dyno-121/best-1-4-stock-turbos-468456/

that's 11.2 on stock sequentials @ about 350rwhp

three ingredients:
1. slicks
2. perfect launch
3. good driving

Low 11 easily with your eye's closed and if your really good, you may be able to click off a high 10.

exactly right. The key here is traction, and a good 60 foot.

Since no one else is asking this, what tires are you running and what does you car weigh? With a fully striped FD on drag slicks you could run in the high 10s, with say 450rwhp. But if you have road tires and 400lbs of sterio and audio equiptment with the same 450rwhp you are probibly looking at 13s.

My point is, there are more important factors than just Hp that transluate into low ET's, ......and that is weight and traction.

yes because we all know 4 speakers and a head unit weigh 400 lbs. Now if we could only radio control the car we could eliminate that useless and heavy driver...

I think he means that if you don't have a clue what ET your car is going to pull you're clearly not someone with a great deal of drag racing experience. Everyone likes to think they're a great driver but when you come up against someone with a lot of experience and skill you'll find out how good you really are. For example when we ran the One Lap Jeff L. did all the roadcourse driving because he'd kick my but on any road course, he has lots of seat time and skill doing it. On the other hand I'd hammer him in a drag race. As I mentioned before Brooks was actually a pretty good driver but I ran .6 or .7 seconds faster than him in the 1/4 in his own car. It's a bad idea for you to bet any money on any race in my opinion.

305's? How wide are those 57pros?

You may want to consider M/T ET Streets just to keep the axle's and diff from exploding.
