I was at the track today (E-Town) and ran the 1/4 for the first time.
Let me just post my mods first. Power fc....Intake...raceing beat c/b......catco cat ....99 spec twins....ACT s/s ....ACT light weight flywheel....DIff. brace bar....KDR anti det. device....Toikico 5 way. (set at 4 rear 5 front...)RS*R springs...
First run was 15.053... at 98.85 60' was 2.632 I reved up to 3k and dumped it I was getting very bad wheel hop Finally got traction....
Sencond run was 14.910...@ 98.41 .60' 2.354...
And third was 15.433..........


How the hell did I do so bad?????Do I need to start out at a lower prm????
I was very close to the end at 7,500 rpm. in third gear.do I need to shift to 4th.?

Im thinking that my injectors are maxed out.......

Looks just like you had some sucky launches. Practice practice practice. First time ever at the track was in my Integra LS. First run was a 17.4 By the end of the night I had it down to 16.1 (should have run a 16.0). Just keep at it.

Well, first off your suspension setup and light weight flywheel are hurting you. Next what boost are you running? What cat is that? I'm not familiar with the "catco cat" is that a upgraded or high flow cat?

Your car should be running low 13's at least. If I had to guess I'd say you either have a boost leak OR that anti det device is robbing too much power. With a intake, dp, catback at 10psi and the stock computer running street tires and the rest of the car bone stock I was running low 13's.

I'm with SPOautos here...

What boost pattern are you seeing??

I can bet you it is a boost problem. Because I remember when I didn't get any boost during the secondary, I was in the high 14's all day...

Im not 100% sure what the boost pattern was.It didnt feel like it was pulling hard at all and I was pushing it 100%I also need a Idle Air Control valve. It was very hard getting off the line w/o stalling.

Bro,
just get a set of stickier tires.. The BF GoodRich Comp. Drag Radials are really good.

Get a boost gauge and see how many lbs you are on. I'm still surprise you have all those mods on and no boost gauge.

HAHAHA thats absolutely horrible. I think you should have gotten mid 12s to be honest. First time at the track doesn't really mean much if you drive your car good on the street thats all the practice you need.

Well good luck next time but I also agree that your trap speed is really slow so there might be a boost leak. Did you get a 2.6 60 time each time? that would really explain it. You should be able to get at least a 2.3. I cant say much because the best I got was as 2.1 on street tires and 2.0 on nittos my first time. But I trapped 112 12.8 in the stock twins car and 121 12.1 in this one so at least I have that going for me.

There is something horribly wrong with your car. You should be well into your 4th gear at the end of the 1/4mile. Get the boost gauge and examine your boost pattern. That the first thing to do on these cars anyway. You can then work from there...

L8NightDrifter

did you buy your car with the mods and never been in another rx7 or what? nevermind the 1/4 time. if there somethng wrong with his boost that hes running that slow, i would think it would be very noticable in everyday driving to anybody whos ever driven a rx7 in good condition.
and i myself have never raced at the track, there is none in my state, but i have many freinds that have races and i went to watch. back then we only had hondas with basic bolt ons and maybe a few gst's but 7 out of the 8 friends i went with all ran times that were close to the advertised times, like 15.5 in a gsr, or 15 flat in a stock gst. it was most of their 1st times at the track too and we were only like 18 back then so its not like my friends were hardcore street racers. i havent had much time being at the track, but i havent seen too many ppl that run so much slower than what they should be consistantly.

i really cant see any other explaination other than, this guy has never driven in a 13 second car b4 and doesnt know what its supposed to feel like. because if his car is capable of 13's and he is just very bad at racing his car, i would think all 3 times wouldnt be so close. but maybe im wrong

*****Update***** Fri. I went to KDR And Dave dynoed the car.He took the cat I had on and looked at it......It was getting clogged up. When I was at the track I had that cat. on.
So Dave put my M/P on and The 1st run was 278 at he wheels!!!Even with the M/P on!!!!
I was to rich from 6k to redline.
So he leaned it out a bit. Got 289 to the wheels 3rd. gear pull.
The 3rd. pull was 306 4th gear pull.The injector duty clyle was at 91% 7k rpm.
So that pretty much sums it up, my car need a baddddddddddd tune!!!!!
Ill try to go back to the track before the season is over.

Psi. ( Dave) said the last run was at 12psi. but on the sheet it has 10 psi.????

With all that stuff on your car, you better have had a tuning issue, and not just practice! Unless you really sucked... I suck (only have gone 2 times to the drag strip) and am hitting high 13's with less mods than you... on street tires at 32psi....

btw: I dynoed at 275 at KDR, so you since you originally were somewhere less than 278, you were still doing pretty sucky, and could hit high 13's with practice alone... with that 306....
