Ive got a 90 vert. 110k miles on it in good running condition and all. I just got it so I haven’t had allot of experience with it, (and to be honest I can’t say anyone has showed me how to drag race) so I don’t know what is a proper rpm to shift. The previous owner put an aftermarket TAC with a shift indicator (witch you can set to tell you when to shift at a certain rpm). Anyway I don’t want to ramble but, he had it set at about 6k rpm or so... now... Mazda says that the non turbo FC new off the showroom floor's HP peak was at 7k rpm... now... would it make sense to shift at 7k rpm or should you ride the gear out to the red line? (Witch is 9k I think)

When I first really got on the engine, right when I got the car, the shift light startled me so I shift when it told me to. But it seems like the car should be faster then it is when I shift when the tac tells me too.

What am I doing wrong?

 

your using a monster rice tac for a non-modded n/a......thats whats wrong there is no point in that at all. So remove the Tac..... When I had my n/a I used to shift right around 7900 or so...and it was pretty much pulled great up till then. Past 8k it kinda died down.....

 

Why an after market tach is what Iam wondering, does the stocker still work.

 

yeah..if the tach does work..ditch the aftermarket one...we have a buzzer that lets you know your at redline..

 

No one can really tell you when the best place to shift is, the peak power can be in slightly different places depending on the car and the mods. The best thing to do would be to get your car dynoed, then look at the graph to see where you are making power, and where you stop making power.

In my 91 FC I used to have, when it was totally stock it stopped making power above 6500. Granted, it could go to 9000, but there was no point since I was making less power. So I would shift around 6500, it would drop it down to 4k, and all was well. After I did intake and exhaust, that shifted the power band a bit, and 7500 was the best place to shift.

 

yeah i thought it odd as well. but it came with the car so i took it, the original works and it does look kind of tachy, so i shouldnt shift till i get to 8k or so? as far take off, what kind of advice would you give me? when i took off the first time i reved to about 4, poped the clutch and floored it.

 

lol you said tachy

 

Oh yes, haha, no pun intended

 

lol Don't forget the shortshift.

 

the guy who put that peice of crap in there should be shot

take it out

shift at 7900-8K

i take mine to about 5k when i take off

some ppl like to skrrt a little when they take off as opposed to bogging down

have fun, dont blow it up

 

hey uhh.. how quickly should you let out the clutch when you launch?

 

That was my next question

 

na vert = slow

Just cruise in it dood. Teh rx7 vert is like the best vert ever for cruising. Sell teh tach to some honda dood who aint never gonna get any chicks with his car.

 

depends on each car....and how much you like your rear axels. I know plenty of ppl who have snapped the rear axels in a modded NA. the T2 rear can handle more but has more power so almost same prob. if everything is perfect at the rear or its stock/mild mods, you can dump as fast as you want, my NA had stock rear end w/ gxl lsd and exhaust and intake, I dumped fast and didn't hurt a thing. If you are a little worried upgrade the axels. prettyy much just use your judgement

 

Th then E pal. English, learn it.

 

Teh owners manuel and Search dood, learn it.

 

The drivetrain on a T2 can handle up to 400hp if I recall correctly. But then again why drag a car that was made for the twisties? Vert in stock form = top down, music on crusing down the highway or some nice back roads and having fun and maybe every once in a while goosing it. You'd be surprised how much fun a 'vert can be as it is.

 

Yeah i wasnt planing on making it a race car persay i just wanted to know if my technic was on or off. i wanted to be sure i was geting all i could out of my car.other then the gay tach i got a prety great car. I love it!
