Track Testing ZZP Motor and ZZP/EFR Turbo
A couple weeks ago, we installed a zzp 2.1 liter lnf motor with zzp block girdle, zzp rods, wiseco forged pistons. This motor also has our ported head and s2 cams with larger fuel pump lobe. Running our bolt-on zzp/efr turbo and full zzp bolt-ons, this setup has been dyno tested to 567whp at 30psi running on E85 from our local Mobil station that tested at 87% ethanol. At 475-500whp, the DI injectors were being pushed beyond their optimum window, so Iam running our single extra injector kit and controller.(Same kit run by Scythe Snake)
With the race season winding down, I wanted to get this car to the track to see what I could put down. I headed down to US131 Motorsports Park in Martin. The weather was great and the track was alright, but my slicks are 2 years old and not in the best shape anymore. All passes were made with 16-18psi in 1st gear and switched to the high boost setting down track.
For the 1st pass, I launched very conservatively and put down a 1.84 sixty foot. I switched to high boost- about 26psi towards the top of 2nd gear. I shifted pretty conservative and finished with an 11.2432 at 132.16
For the 2nd pass, I launched a little harder for a 1.78 sixty foot. Unfortunately, I forgot to switch to high boost until part way through 4th gear. This pass was a 11.30 at 130.
Pass #3 was a little better sixty foot at 1.77. I hit high boost(27psi) about half way through 2nd gear. This pass got it done with a 10.9985 @ 133.61!
ZZP LNF Cobalt Runs 10.99 @ 133.6 - YouTube
Pass #4 was run the same way, but the sixty foot was a little slower at 1.80. This run was a 11.06 @ 134.40
For pass #5, I decided to turn it up a little(29psi on high) and also tried to launch harder. I also started no-lift shifting the 3-4 shift. Unfortunately it spun pretty bad on this run for a 1.88 sixty. The pass was 11.01 @ 136.85.
ZZP LNF Cobalt Runs 11.01 at 136.8 - YouTube
Pass #6 was run the same(29psi and nls 3-4). I got a better sixty foot at 1.81 and ran 11.00 @ 136.84.
For pass#7, I decided to nls 2-3 as well as 3-4. Unfortunately, thinking about this, I forgot to hit the high boost switch until 4th gear again. I finished with an 11.18 at 132mph.
At this point, I decided to call it a day because the track just wasn't good enough to put down a good sixty foot any more. With a 1.68 sixty foot and 30psi on the high setting, we should be looking at a 10.6. Maybe next year...

Very cool. Nice work.
I am curious though... It sounds like you are hitting a switch during your run to access the "high boost" in your later gears. I was under the impression that this kind of function could be done automatically with the tuning software. Is this not the case for you? If it is, is there a reason you don't have it tuned that way?

Most of the parts on my car are already available. While our EFR is not out yet, we can build an EFR kit for anyone building a serious setup like this.

Can you pm me what i need for this or link if you guys sell it? This would be nice to have going into winter with no traction and i'm sick of burning up tires. Third gear i can control but 1st and 2nd is a smoke show using anything over 1/8 to 1/4 throttle
