Alberto are you going to get cams and/or headers? If so, which ones? I'm curious to see how you do with those additions mainly because you've had dynos, as well as, track runs all the way through your mods. Actually, I'm more interested to see how they affect your runs because that's more "real world" than what a computer spits out. Tischer told me they'd have to drop the tranny to replace headers so I figure when the time comes to replace the clutch, I'll install a JWT setup and headers at the same time. However, I still haven't decided on the header. It seems like there's too much BS out there to get honest opinions on a decent header that will make a real world difference. IMO the difference in your times would be evidence enough for me.

Im building a block and going with a Greddy TT, with some JWT cams later on down the road so Im not big into headers. All I can say is that it seems to me, from a lot of peoples numbers that they lose peak TQ with headers. I know it doesnt make sense but I always see cars with a similar set-up than mine with headers and they are lucky to make the same power and usually its less TQ. I wouldnt want to point you down the wrong direction, but I wouldnt bet on headers making a big difference in a n/a Z without cams. If I had to get headers Id do the top-speed ones, they are inexpensive and more than a handful of people have seen gains, unlike other company's. For what its worth, times and trap speeds are 95% driver related-the only other Z's Ive seen trap 105-106 have had headers, and some even had cams, and one guy that trapped 106 has similar boltons to me, and has headers and a clutch/fw over me. I trap 107 what does that tell you? Its not that headers, and cams dont do anything, its just that I can extract more out of my car, and just having headers over the next guy wont set you apart from the pack, or guarantee you'll win or pull another Z. If you want something to put down other Z's-and similar performing cars in general learn to drive your a$$ off, just my opinion, and its free. BTW now that the weather is getting nice all us MD Z's should meet up, check out each others cars video tape a few races

Very impressive e.t.s and traps imo. Any dyno numbers? How heavy is your car?

1st run:

60ft - 2.216<----Worst I have pulled ever, usually pull 2.0's.
1/8 - 8.889 @ 83.58
1/4 - 13.585 @ 106.17 <----Very happy with this trap speed

2nd run: I mounted up some used slicks I bought-my first run ever with slicks, please excuse the weak a$$ 60ft, I didnt pull the brake fuse I barely warmed them up....

60ft - 1.956 <----Weak I know
1/8 - 8.481 @ 84.51
1/4 - 13.136 @ 107.09 <---This is the highest n/a trap speed Ive personally seen/heard of on here for a Z

3rd run: Pulled the brake fuse, warmed up the tires more, and what do you know I fuked it up-I bogged bad off the line, I dropped the clutch at about 6000 rpm's, I should have slipped it some, anyways...

60ft - 1.895 <----Better but still $hit imo
1/8 - 8.467 @ 83.87
1/4 - 13.161 @ 106.15

Overall I am VERY happy with the traps Im pulling, especially considering I dont have headers or cams. I am also very happy for going 13.1 on a weak 1.9 60ft, Ive seen guys go 1.7's and run 13.0-13.1. I really wanted to keep running on street tires because with my usual 2.0 60ft, I would have been 13.2-13.3 easy. And if I would have hit my mid to low 1.7 60ft like I wanted to on the slicks 12.8's are not out of the question. I just need more time to learn how to launch them, play with tire pressure's ect, Ill go 12's this season for sure For those that dont know my mods are : JWT Pop-charger, Crawford Plenum, Test-pipes, Crank Pulley, Injen Exhaust, Technosquare ECU---this set-up = 262 whp 252 ft lbs SAE corrected on a dynojet. Comments, suggestions? All are welcome....

**BTW I have a videos of the runs, Ill post the 13.1 @ 107 run later today or tomorrow.
Good times for those mods.

I do find it a bit odd though that the MPH stayed at 106 on the last run compared to the first non slicks run.

Usually when you shave off that much time on your 60 ft your trap speed goes down.

Were the slicks a different diameter than the street tires?

Overall the trap speeds seem awfully fast for your dyno of 262 RWHP. Is the car lightened up?

From my extensive experience at the drag strip I've NEVER seen a correlation between 60' and trap speed. Some days at the track I'll have my highest trap of the day on my best 60'...some other days it will be on a much worse 60'. In fact...on really bad 60's my trap DROPS significantly because I've wasted track with wheelspin.

Thanks.....the stock diameter of the rear tire is something like 26.2", the slicks are 26", so very very little difference. My highest trap came on the 2nd run on slicks I went up 1 mph on them. As far as weight reduction I took the spare and jack out, and ran the car at a low gas level, still had passenger seat and all the interior panels.

That's odd, because I've always seen a correlation and so do most other people. If you spin a lot off the line the computation for your trap speed gets thrown off and your final trap speed is most always higher than if you hooked up well at the line.(if all else remained the same such as shifting and such).

Great driving Alberto!

One question: I used to power shift my old beater all the time but I'm too chicken to do it on my Z33. Doesn't power shifting but a bunch of wear and tear on your tranny/clutch?

And keep the kill videos coming-they're very fun to watch!

As long as you do it correctly you will be fine. I am 50K miles strong on my motor and clutch, with no issues. If you are the kind that jumps 300+ revs in between shifts then Id say your clutch and FW will be toast soon (will proly glaze) but I dont jump rpm's when I go into the next gear-its all about timing. Im working on getting some more vids withing the next few weeks

Is that your stock clutch?

Its the stock pressure plate, iirc they gave me a new friction disk when I had the 2nd tranny put in. So its 1/2 stock And still holds 6000 rpm launches and powershifts over and over...

Your car is fast. Can I know where you bought the technosquare ECU? Does it do much in gaining HP? How much is that cost? Do you have any links that I can look for the ECU? What did the STI get that you beat it?

Thanks, I sent the ecu directly to technosquare for the flash. Look them up, I forgot the website off the top of my head. On my car the ecu yielded me 9whp and 12 wft/lbs peak, with good tq gains midrange. Its $600 for the custom flash with raised rev limiter and removed speed limiter.

I mean what mods does the STI have? The STI that you killed.

So, you just took off the stock ECU and sent it to technosquare and they tuned up the ECU right?

That STI had a down pipe with HF cat and a cat back. Yes, you just send the ecu in for tuning with a mods list, and I also sent in my most recent dyno with a/f so they could tune off of that. Dont look into getting an ecu until you mod some, and your car is running lean, an ecu on a stock car or basically stock car will yield little to no power gains imo.

cool.. Any other cars you beat? EVO 8? S2k? If you get TT kit, do you have to reflash the ECU again? It will be much faster if you get TT. Greddy TT is nice. Do you think that Supercharger is better than TT?
