Are you running a 2 Bar MAP?

 

Tell your brother don't always believe the mags. Those times are on cars that are driven by great drivers that are willing to beat the hell out of a car that's not theirs. You can't match those times without a very liberal amount of clutch slipping, doing a hard burnout on high dollar Z rated tires, and power shifting flat footed. Drag radials...no problem...11's, but not bone stock. I got 91.xx mph in 88 deg temp with my C5Z bone stock. 8.21 was my best without powershifting and so so track prep that night. A viper GTS was running about .06 quicker. Later that season on a cold night at Kennedale a C6 ZO6 went 7.87 when my truck ran 7.64. Hell of a lot more fun on the highway though with a vette. They just don't catch any wind.

 

BTW meant to say congrats on your new times! The grin just keeps gettin' bigger doesn't it?

 

damn Tom, you got some lofty goals, haha!
It's all good though, so do I probably. I just wanted to get solid, consistent 12's and did that, so I won't be too antsy this winter, haha.... like I was saying at Milan awhile ago....

But seriously if you could get some decent rubber out back I bet you'd (should) be beating me if you could get your launches down. You're lighter, don't have heavy *** factory 20's, and should be making more power once you get your tune sorted out!

 

Jman, I replaced my original w/. the 1 Magnacharger supplied, which I believe is 2 bar; what's the significance of that?

I hafta convert your 1/8 Mi ETs to figure out your 1/4.

I hear ya, I'll tell or show him your post. Ya, I know he'll always be lighter & more aero, I just want my truck to perform at a high level, more than most "stock" cars. On the street, it's a blast. I don't get too worried by most trucks, unless 4WD or AWD. Take a SRT8 Jeep for instance.

Ted, he's a fan of buyin the most powerful factory piece, like a Z06. Had he not lost his job, he planned on gettin a C6 Z06 as well.
I'm usually bucks down, so I take a platform & put money it as I can afford to make it mine. So it's a big deal to me when I can afford that next go fast goodie.
U learn to appreciate it more, IMO.
I'd rather take a lower priced vehicle or a lesser in the GM ranks, or whatever brand, then bring it up to, perhaps beyond, the superior vehicle. Even if I had cash. Everyone expects a Vette or Shelby to be fast, & they are. I like the shock factor of a truck or a Camaro kickin the **** outta most anything (be it a BMW, Porsche, Audi, etc.). I do appreciate all performance tho, esp. domestic.

Ted, thanks. Yes, the grin just keeps gettin' bigger.


Dave, I want my truck to stop, handle & go. Looks too. So, it won't be glamourous, high dollar build or the fastest or (fill in blank), but it'll my Pro Touring iteration as I see fit. I'm fine w/. 11's or 12's. I've addressed the handling, as it does well on that front now. I'll go back to that a little bit later in the build.
Big brakes, hence new wheels & tires I wanna try for next yr. I mean like 14-16" rotors.
I'm all for function then looks.

I don't foresee havin 16's too much longer, depends on $.
I see some rims in a bigger size, 8-9", maybe 9.5" wide at most. Cause I want as big as brake as I can stuff w/o compromising handling & drag E.T.s, think I'll likely say no to 17", & go to either a 18" or 20". I don't want big wheels for bling factor, just big brakes. Some 18 x 9" on all 4 corners would work best I think. However, I may need help from a chasssis engineer.

All that said, I wanna find some slicks in a 18" w/. profile similiar to my current 255/70/16 near 9" wide +/- 1/2".
Anyone have some ideas? I'm thinkin M/T, but over winter I'll research brands, so it's still open.

 

Usually it works out to multiply by 1.55-1.57 in most every case depending on how hard you can 60'. I use 1.56 or .641 to go the other way. I ck back later.

 

Mph is a better indicator of HP.

 

12.73-12.81-12.89, but u like the middle for an avg., so that'd be what I go w/. as well. So, u would run a 12.81.

I checked a few days ago usin an online calculator, my MPH is good for 12.9sumthin, usin my PB MPH of 102.62.

I wasn't planning on racing anymore + winter is coming, & since I don't want road salt on my QA1s, they weren't on for these 6 runs. Only on the outing on 10-24. I now weight in the back would help my traction, but I also had my Snugtop lid on. Supposedly that's 100-125#, maybe more. It was how I DD it tho.

 

Do you ever log the truck with HPT?

2bar is good for reading up to ~15psi boost.
1bar is good for reading only Vacuum.

You can log it and see what your kPa is doin.

 

Gotcha on diff betw. 1 & 2bar. My friend was checkin log on HPT at track. I need to learn to do basic stuff like that, yet understand what I'm lookin at too. I'm not computer saavy so that doesn't help.
He said to write a few ing down, as he read them off. I'd need to ask him what it means, but what I can figure is ...
@ 3600 rpm, timing is 18.5°, & 13° @ 6200. Says I have alot left in timing.
The Dyn. Cyl. is .73-.79. What's that mean, is it conservative or do u need to know at what place that occurred?
Isn't that the airflow reading via MAF or did I say that wrong?

I only mess w/. trans, fan setiings, little stuff. Til a wide band is in there, it'll stay that way for a few months. But I should how to fully utilize HPT.


In spring, I can better assess when all my gauges are put in; W/B, Boost / Vac, Fuel Press. & a DPIC for play like if I can't get to track but I go to Mexico for a 0-60, 60' or a 1/4 run.
Those tools will help the tuning experience for sure.
