Well, tried out the VI to the track.....
First off let me the weather wasn't good for racing one bit. Temps were in the 90-95 degree range with humidity in the 60-65% range with a falling baro (29.90). I dug up some slips from when I ran back in July of last year after installing my UDP. The conditions I ran in tonight were nearly the exact same as July 2001. The only difference between now and then, in terms of mods, was the addition of the VI. Last July I ran a best of a 15.25@91.48mph with a 2.27 60' with a lot of 15.3s@91. I set a goal and I got it. Tonight, my best was a 14.95@94.99mph with a 2.33 60'. I ran one run with the VI not activated and I got a 15.30@91.90mph with a 2.34 60'.
Here are my runs:
14.95@94.99mph with a 2.33 60'
14.99@94.74mph with a 2.29 60'
15.07@94.74mph with a 2.30 60'
15.05@94.02mph with a 2.33 60'
15.21@93.99mph with a 2.43 60' (huge bog, 1st run of the night)
15.30@91.90mph with a 2.34 60' (VI not activated, turned off RPM switch)
Most of my runs were back to back (14.9s, 15.0s, 15.2&15.3). The engine was scalding hot all night and never cooled off. I did 2 runs at a time with 20minute shutdowns. My 60 foots were terrible with lots of spin.
In a nutshell, the VI was good for about .3 of a second and 3mph. The non-activated VI shows proof that this thing does indeed work. I have no doubt I will be getting a best ET and MPH when it gets back into the crisp 60s.

A little off-topic but I want to take this opportunity to ask you variable intake manifold owners to please use something other than "VI" to call your manifolds. Use VIM or something. As we all know the search doesn't index anything that is 2 letters long or less. This would make it easier for people to search on your post in the future should they need more info and maybe curb the many "whats a VI and where can I get it"? posts.
Btw thanks for your many trips to the track. I can't wait to get my variable intake manifold

That just rocks!!!!1
The times on the VIM are just excellent. For 1,000 bucks you can lower you 1/4 time dramatically now.. ypipe, exhaust, intake, VIM...
I just hope the others with the VIM will get to the track soon...
Nealoc... i'm hoping you can hit 13's...

It's called weather conditions. The higher the Temp. and the higher humidity equals higher 1/4 mile times.
90 degrees and 60 % humidity and pulling a 14.95 @ 94.99 mph
That , to me, is a great time considering the weather.
Dave I have a question... the 14.68 @ 97.79 mph was run with what mods and what was the weather conditions? I am just a little confused about that.
Not trying to call you anything, just a little lost.
Thanks

I think it's just too much wheel spin. Just look at their 60" times. It's almost identical with or without the MEVI. Only if they control wheel spin can they get faster.
Maybe you guys need some more practice or a little suspension tuning. That's what friend had to do with his IS 300. Without changing anything he learn the power curve of his car, better shift points, less wheel spin and his car with just an INJEN intake ran a 14.6 @97.85mph.

Dave, are you shifting to 4th or riding it out in third? Seems to me that with all that top end, you could just ride out third at least in those conditions. Cold weather you'll be near 100, though, so then a shift might be necessary.

I just need my RPM switch and solenoid, which I already ordered last week, but am still waiting for them to show up.
As for gains, i'd say it shows a gain of 0.3, which is hard to come by when you already have y-pipe/intake.
He ran last year at approximately the same time of the year and ran 15.3's, and now, he's at 14.9, with teh same weather conditions, so that's a gain of .3

Damn summer heat !!
This definitely makes me feel better about my times after the VIM was installed. Also, I changed the RPM over to 4700 and I didn't once notice it do that little hesitation thing I was telling you about. I ran about the same times as well. Any plans made for a dyno day?

You're right, you aren't getting it....
j/k, hopefully some of the track regulars can explain the significance of this difference....

Yes...14.6 with a Variable Intake...another 60 degree day he'll be at 14.2-14.3...that is damn good...he'll be hangin with 2k2 6spd
-Matt
with an intake and y-pipe, .3 seconds is damn good for a bolt on that just adds more flow and doesnt totally rip apart your engine like Nitrous...the VI will be next mod

Re: Well, tried out the VI to the track.....
I can tell you that your going to need more tire size to hit a high trapspeed. Even during those runs you should be finishing 3rd gear around 6300-6400rpm. With the stock rev limiter a 225/60-15 or 225/55-16 tire would have you hit 100-101mph @ 6500rpm. Shifting to 4th gear would only have you around 96-98mph traps at best.

In a nutshell, the VI was good for about .3 of a second and 3mph. The non-activated VI shows proof that this thing does indeed work. I have no doubt I will be getting a best ET and MPH when it gets back into the crisp 60s.
