So the 15 PSI TC is supposed to do 5.7? and about 13.8-14.00 in 1/4

What does the 20 PSI TC GMSI run?

1/4 and 0-60? Ive never been able to find documentation of this... thanks for help.

 

I ran a 13.71 @ 104 with my mods (that includes the GMS1).
And 0-60, my guess would be about 5.2 seconds if I could grab.

Stock dyno: 238whp 241 wtq
GMS1 dyno: 277whp 301 wtq

My car got 13.8 at 107 In Tucson, AZ. About what 5,00 feet or so? All I had was a trifecta tune at the time. I was having traction issues. My 0-60 was probably about the same as JPizzle's.

 

Unless you're REALLY good at executing a 0-60, your'e not going to get the real indication of GM1. Using a *ricer* test which is 60-100 in third gear is the best comparison. A stock TC does it in around 8.5 sec....GM1 only (no bolt ons) is about a 1.3 faster at 7.2ish. HTP is around 6.4. This is done with a STOP watch while viewing the speedo. If you log it it will be quicker, since the speedo records a couple tenths SLOW. As far as 0-60....you can use the 60-90 time as a very good indication. These #s match very well with 0-60 capabilities.
GM1 should do it it close to 5.2..stock is 5.7. HTP will do it in 4.8 sec.
As far as the Qtr...it will probably be reduced the same as the 0-60 time. That would put GM1 around 13.3...for a WELL EXECUTED RUN.
This is *BENCH* racing..but still a good indication, since it rules out DRIVER SKILL.

 

Ronn I don't think a GMS1 will cut a 13.3 1/4 mile. If it was bolted a little then yea but with a stock airbox and exhaust the GMS1 won't hit a 13.3 ET. My car will hit a 1/4 in 13.8 at 107mph and at the time it was 22.5psi trifecta selectable and an airbox mod. I think with a great driver the GMS1 could probably cut a 13.5 ET. HP tunes and trifecta are better than GMS1 but they just aren't warrantied. Gotta pay to play sometimes guys. Thats just my .02 cents.

 

It could hit a 13.3 in negative DA on perfect track conditions. Keep in mind, one stock SS/TC did a 13.5 when the planets were aligned precisely at negative sea level conditions, while the moon was close enough to the earth to enhance gravitational conditions.

 

I could cut a 13.65 on stock tune, I don't remember the trap speed. It got better with KDWs at 24 or so psi, I tried 21 psi for a while but meh. I don't think elevens are a good indicator of a car's capability.

 

I think the 13.3 would be a *theoretical* limit under optimal conditions....but 13.5 is *close* enough.

 

I'm thinking it's more a traction issue than power. I've got 2 runs in with GMS1/open dp/drop in/"football mod" with a best of 13.39 @ 106.02 ; 2.224 60' on Bridgestone A/S's.
Practice and tires would yield better results.

 

107? That tells me 13.3 is *doable*

 

Yea my tires were yelling at me, but the OP asked about a GMS1, which I assume is unmodified apart from the tune and GMS1 sensors. A GMS1 won't be quite as fast as another tune. Go custom tuned if you want power cranemaster, HPT or Trifecta are the way to go.

Also, FRQ FLYR, you had a catless and a drop in. I want to rock that football mod thought that would help until I can afford a 1500 dollar suspension. how much did it improve your 60' times? Mine were like 2.5 or .6 on stock tires with 24psi in them haha... I was running more pressure in my intake than in my tires, just thought of that.

Yea maybe. It would have to be at the right track at the right time with the right driver. It would be no easy task.

 

^ Made 4 passes on stock tune/tires ; best 60' was 2.346 (14.15 @ 105.32)
Our local tracks future is uncertain and I don't get there often so I used the footballs to get the most out my setup/skill level. They def help as does the (open) dp. So yea I'm not exactly S1 only. Nice to know that this tune and a few supporting mods could probably approach 12's-tires/chains/f-***** would need to be part of the equation.
