FI guys how fast are you?
 

How fast is your 86 under boost? I'm sure it improved your strait line performance but how bad did it wreck the driving performance. I saw a video where the guy would just blip the throttle and go sideways. I can't imagine my car having 300hp or 300ftlbs being so so lite in the rear but it would be fun to test it. Guess I'd have to lite foot it in twisties

:search:

I wouldn't imagine it would be hard to control due to the engines being low torque engines (torque to HP ratio). With stock tires it would be though.

Ya stock tires and suspension in general would scare the crap out of me at that hp/torque. I can't even imagine trying to drive it in the rain or cold.

Im currently sitting at 250whp (stock car is 160whp) on stock primacies while I wait for my rims to come in.... here in the uk ~40F outside the other day, it felt like I was rolling on wood.

Don't know what tires he had but he was gunshy at first the he warmed up to it and in the end that lil fucker flying

mines Cosworth and the throttle calibration has a lovely smoothness to the power delivery which does help.

Fatter tires.

FI guys are just a little less slow thats all

Is this a question for why are you not getting traction in FI? or is this a legitimate question about track times with FI vs NA?

This car has characteristics to slide out stock. Thats how it was designed with the skinny tires and stiff suspension. Wider tires and tuned suspension as well as tuned torque curves will fix the problem.

Now, I know of a person who was NA then went FI for track and then back to NA. Why you may ask? Well a couple things;
FI gets really hot on the track.
You can beat on NA and not have too much heat problems.
He also beat his best time at Laguna Seca while NA rather than FI.
He would also tell me about how he would have to end sessions early just because his car was getting too hot.

Well why not Headers and E85?

All FRS's are slow so NA is slowest, E85 headers and other bolt ons is a little less slow, and FI is a lot less slow :D

But if you put a 2jz in it and replace the frame with tube steel and fiber glass. It's actually really fast

That would be what I call the least slowest of them all! .... but still slow because FRS :lol:

Too fast!!!!

Dont chuck all FI kits in the same pot. Some overheat more than others.....some dont at all :)

As for track times N/A vs FI well I suspect it is a matter of driver ability. Faster requires more skill to go 10/10ths.

If your fi is too hot... You just haven't spent enough money yet. Better radiator, vented hood, etcetc

I'm at 240/200 at the rear and need to upgrade wheels & tires. Like mentioned above, very slippery on stocks. I can step on the throttle in 1st-3rd and spin no problem especially in any wet weather.

It's fine... unless you're driving in semi-cold weather, in the rain and that when you decide to give throttle the rear jumps in the air (tires spin in the air) and continue spinning once they regain traction.... that's gonna be a bad time.


Aside from that, I can make it go sideways if I want to but stay composed if I need to. I have a KW C38 kit btw (so top end power is where it's the riskiest). Keep in mind I also have a lot of suspension/handling components that were also modded.

Means you get to have more fun :D

I'm currently on stock-size winter tires and make about 265whp with my supercharger. With traction control off, I have to be very careful accelerating from a stop. If I apply any more pressure than 'bare minimum' to the gas pedal, it'll spin the tires until third gear.

Find someone local to take you for a ride.

I'm 335/276 and with 255 rear tires and smooth driving I don't worry to much about spinning when the weather is nice. Sure if you hammer it they'll spin but come on now.

The secret to the primacy's is that they are slippery at anything under 400whp, that's when they come alive! :thumbsup:

I had 260/210 with 255/40 Continential ExtremeContact DWS06s and broke 1/2/3 as well with the Sprintex kit.
Then again, I also had -2.5degree camber in the rear, so that could explain 3rd with such a large tire.

Ya I'm entirely stock wheels and tires and blimping the gas in a turn does result in a sideways car. Going strait I just spin the tires. It's all fun for a afternoon, weekend car. I'll never track it.

I rather have no traction and not eat factory transmission gears at the moment.

Man I spin all the time must be something wrong with my car, even on just wastegate springs only rolling on it they break loose......




But I like it
I'm only 640/521

Damn Justin I thought you were higher than that...

I am now lol Video and more new build info after TX2K

more than you can afford, pal.

In for closed deck build.

To give a reply. I run the phantom supercharger it gave me a 13.8 @ 101. Stock was 15.1 @ 92.

Hahaha, loose nut behind the wheel is your problem.

12.8@110 on my current setup

Shit econobox tires

very good possibility, you know me, I live by the saying " no one can hear you scream at redline"

Lets just say I decided to call Pauter to see what they rate their rods and he said 800hp should be fine. I said I will let you know soon.....
