New E/T..I'm pleased...for now!

I finally got to the track this weekend with my new combo. My time was as follows:

E/T: 13.45
MPH: 105.60
60's: 2.1's - .4's

I need sticky tires!

I am pleased for now with those times. I know I can get into the 12's with a set of Nitto's or other sticky tire. Also I know there is more power in my motor. Right now I just have a mail order pcmforless tune, I need to learn to burn my own proms to get the full potential of my motor. So that will be my winter project.

In two weeks time I am going back to the track. I will have Nitto 555R's on my car. As well I will have my MSD installed, and fp guage hooked up so I can adjust my fp. 12's should not be a problem.

For those who are wondering what my combo is, to make it short I have a Minirammed 383 that has a long way to go in tuning and tweaking!

Yep, you are on your way. You might want to check out the Mickey Thompson ET Streets. They now come in a radial tubeless version. Allen

The cam I am using is the LT4 Hotcam, I purchased the entire kit with the 1.6 rr's and all.

As for the heads, that is a long and painful story. Let's just say I had to "settle" for now with WP Torquer S/R's. They have been heavily ported, and are also plained. However I will be getting a set of AFR 210's in the very near future. That is what I wanted in the beginning.

u should be running a little better than what you're running now with that setup. i think the problem might have to do with the cam and heads... to make good power with the MR, u have to get heads and a cam that would help the intake out from 4000-7000 rpms. if you're going to go with the afr 210's, may i suggest a longer durration cam? something that'll pull hard up to 7000 rpm's to make the most out of the intake. i don't know if you're car is automatic or manual, but a 3000+ stall torque converter would help you get to all that top end power the MR dishes out. good luck with the car, hope to see you hitting 12's soon

Thanks for the reply dj.

My car is a automatic and it is already equipped with a 3000 stall converter. As I said, I wanted a bigger set of heads in the first place. But because delivery turned out to be a nightmare I decided to use what I had at the time to get out of a jam. In other words the summer was here, I wanted my car on the road, and I wasn't waiting another 4-6 weeks for the AFR's!

The LT4 Hotcam is a similar story. It was originally purchased for the old TPI'ed 350. But when I decided to go with the stroker, after finding gas in my oil, I used the Hotcam because I hadn't used it at all up to that point. It was still sitting all fresh in the box. So it was another, why go to the hassle and expense of another cam when this perfectly good one is sitting here and will do for now. The building of the 383 and Miniram, and full MSD and so on and so on was enough of an exspense at that time.

But I am pleased with the current combo and times. I know with a sticky tire there is a 12 second pass in the car. And when I hit the button, all 150 hp of it, 11's should be no problem. Especially if my kits works as well as the one my friend has. His is a 150hp kit, he went from 12.80's on the motor to a best of 11.55 on the juice. Giddy up!

What do you mean by "MSD," which components? If you get a ingnition controller,(multiple spark discharge) get the digital 6. Anything less is really only for daily driving and lower end power.

I meant he actual MSD box itself. My MSD coil, billet distributor and 8.5mm wires are already installed, the only thing left is the 6a.

hmm... what type of headers and exhaust do you have? i think you should be running higher than what you're running with a 3000 stall converter, that cam, those heads and the MR. i think the HSR would have been a better choice of an intake for that cam and those heads.... only way you'll do the AFR's any justice with the MR is to go with a larger cam and higher lift. im running mid 12's with a comp cam 503 cam (224/230 dur), 1.6 rr's, hsr, ported l98 heads, hedman lt headers, custom y-pipe, hsr, 3000 stall converter, and a bunch more goodies. are you running the stock prom?

You really do want the digital 6. It is much better than the 6a. 6a only gives a multi spark discharge untill 2,000 RPM after that it is a paper weight. Really only good for putting around, cruising low, idling and starting. Digital 6 WILL actually multi spark untill 2,000 RPM and still produce a hotter and longer spark than the 6a. Even bigger plug gaps. Trust me, experience.

I should/will be running higher on this next race weekend. As I said those times are on street tires. I have to peddle it off the line, thus my times and 60's suffer greatly. Any hard peddle at all and she breaks the tires lose causing my e/t to be even slower.

And I agree, a larger set of heads and cam would work much better with the MR. But like I said earlier, these were just temporary parts. Right now my tune is a pcmforless one, but I plan on getting into prom burning this winter so I can improve the tune.

Thanks for the reply!
