Thats a nice trap for a stock turbo. You can get into the 12's with a 107 trap. Where you getting any wheel hop at the line?

antman0408 05-19-08 01:31 AM

I wasnt getting any wheel spin or hop coming of the line.

Very nice.

That stock turbo is probably running out of steam.

Like said before, you could get into the 12's. Just need to work on that 60' ;)

that time and trap is about right, although a friend of mine managed a 13.1 on street tires with stock turbo and intercooler (obviously pushing those to the limits).

antman0408 05-23-08 10:23 PM

For my first time, I think I did pretty good. I'm sure I can get a better 60' and low 13. I'm trying to run better than a 13.15, thats what my brother ran in his 350Z.

rtperformance84 05-24-08 02:14 PM

ooops i meant to say you run will better lol just keep on goin at it

Rexpelagi 07-07-08 08:12 PM

Nice times. :icon_tup:

If you want to drop the 60' even more you could consider investing in a set of drag radials. 2.1 was the best I could manage on my street tires (they were fairly bald though). However, I got down to 1.79 my first night on drag radials.

Here is a little tip if you want more boost at lower rpm..

You need to install a wastegate restrictor..basically its a .010 insert into a vaccum connector, usally made of brass. any smaller than .010 and you may not be able to get the car rolling without hitting full boost before 1500..

My car makes 10 psi at 3000 rpms and its not possible to get anymore boost in the lower rpms. When I race it, it never gets that low in the rpms, so this will be unnecessary and doesnt make sense. If I wanted boost off the line, I would setup the 2-step feature on the haltech.

I would love to get them but I have no money for them right now.
