How come no one on here is close to that???? There isnt even that many mods on that car. They could get that into the 11's.

I haven't seen that article, but what do you mean noone here is close to that. Trax has run 12.2@112 w/ his mild miniram set-up, his new set-up will easily be 11s. Even when it had an AS&M runner set-up it was running 12.6 or .8 @ 108. And we're talking a full weight car w/ stock shortblock and tranny. And there are a bunch of other people that fast around here too.

note---he said long tube runner, not miniram or SR or RJ. just clearing that up :0

note--Ed just said that Trax went 12.8 with LTR's. He also had AFR heads and a nice comp cam. So yes mid 12's are possible with LTR's!

I think that people are getting way too caught up in times and are overlooking Trap speeds. ET's are not indicative of horsepower. As a rough estimate, if you have 320 rear wheel horse and a 3600 lb. car you can run a 12.99. But your MPH will be fixed. You must have a MPH of better than 104 to run a 12.99 Your ET potential cannot exceed Power indicated by the MPH (This is for the new guys as I can see many of you are aware of this).

For a 12.3@111, you need to have a near perfect traction. Also, was the CHP time and MPH corrected for altitude?

So the Formula Popular Mechanics ran to a 13.15 sec. @ 108.27 mph should be capable of 12's?

TPI Guy

Yes, with the suspension and drivetrain optimized with a good driver. Traxion ran 12.8 @108.

Actually, I think he ran a 12.5 at 108 mph with the AS&M semi-siamesed runners, ported plenum, AFR heads, and 218/224 cam. I was there when he ran a 12.2 at 112 mph with the Mini-Ram and front skinnies.

Ed if you want to see the article just go look in the magazine articles on this site. The new article is a redo of the "Hardrock Camaro" article. If you'd like to see the new article I can e-mail it to you. Anytime I see that 1 company (TPIS) has provided most of the upgrade parts for a mag article I generally conclude that the #'s have been "corrected" Especially when that company is TPIS.

I know of a car running 12.1 on LPR's. That is the best but I have seen several in the mid 12 range.

1991 Z28 ZZ4 with LPE superram base, SLP runners, LPE 58mm T-body,Random Technology ramair,TES headers,24#svo injectors,ZEX nitrous,Walbro 255lph f-pump,Accel AFPR,Random Technology catback,!cats,and mutch more.

well, i may not count, but my 406 has TPIS runners, intake, and a58mm t.b. the engine itself is suppose to rev up to 6200, but all the power is going to be at 5500 rpms. heck, 300lbs tq at 1500 rpms.. im waiting to turn sideways on a launch.

Be careful when you say cannot. There are plenty of bracket cars around the country whose “formulated” HP from the ET exceeds the “formulated” HP from the speed. However, I will agree 100% that you can use the HP numbers derived from speed to see if you have potential for increasing the ET.
