If I launch below 3700 or so on the MTs I bog. |
Dammit Richie , now im torn between the 17's and 19's .
I know the 17's are going to hook the best but ide have to widen a set of rims and use spacers to get the tire to look right on the car and the rims wont match my chrome spyders . On the other hand , i can get 2 more 19" spyders that match and use the 19" nitto for street and track . After looking at the video's i took last night the VY car last night did hook up pretty good on his first run of 12.3 and then got worst as the night went on like everyone else . Who makes the best line lock out there for our cars ? Im sure that was part of my problem last night , i couldnt get the tires heated up real well before launching . |

Richie,
He said the same thing. 16psi and a 3500rpm launch and it pulled him to idle. Complete bog. Ordered a RSD lineloc yesterday along with a tick master. Next up cam and fast intake. |
I am Unreal's friend that he is talking about. I did not slip the clutch at all at launch as I heard so many horror stories about the clutch I just let it out fairly quickly at about 3200 rpm. I did not do a burn out with the 19" Nittos and they basically dead hooked at about 17 psi. I tried another pass at about a 3500 rpm launch with about the same result. I then knew that I had only 1 pass left for the night so I raised the tire pressure to about 22 psi and they spun but the car got a better 60ft. time. I think that the Nitto's will be awesome when I get the correct rpm, clutch release action and tire pressure dialed in. Unreal is running the Mickeys and seems to have them and the car dialed in pretty good for our elevation and track conditions.

Thanks Richie. I was worrying about them being too sticky with a manual tranny. I figure that I could just raise the tire pressure slightly to make them so they did not hook so hard. Our track is closed for the season so I will have to wait for spring.

what size wheel and tire are you currently using ?
They always dead hooked with my auto c5 and that car was always running 1.5-1.6/60's on motor with a little over 500rwhp . They might work just fine once i get a line lock and get their temps up before launching . Im going to try them again Oct 2nd at BMP with a line lock and see how they do . |

I think that you will like the NT05R'sa fter a little practice on them. With a stock clutch, you may find out they are too sticky for it after you get the launch down.

I was able to shift into 4th at the 1000' mark like someone mentioned with the smaller 25" tire instead of running out of gear right at the linewith the 26" . I dont know if thats good or bad .
An added shift takes away time . |
