That is cool that he is successful running a blow through setup .

 

Yea, that's Jimmy's car.. He just got done getting some major tuning issues sorted out.. Great guy too..

Cheers,

 

I remember seeing you were doing a blowthrough setup as well. How much of a bitch is tuning? What issues was he (Jimmy) having?

thanks,

Seth

 

Actual tuning can go either way.. Really really bad, or really really easy..

For example, Jimmy faught with his car for quite a while, only to find out that his new plug wires were toast.. With a new set of wires all his problems went away..

With me, I spent the summer running too lean no matter how much jet I put in the carb. After replacing the carb hat 3 times, I finally got it sorted out.. The EV hat is the only one that wouldn't cause turbulance over the boosters and allow me to get a good tune..

Aside from gremlins like these, tuning is just like an N/A engine really.. Take jet out, put jet in, etc etc... Spend the money on a good carb hat and a good solid ignition setup, and you won't have any of the headaches we did.. (hopefully)

Cheers,

 

Hey andrew, do you have any times for your car yet?

Funny, it seems that Jimmy hangs out at a lot of the same boards/lists as I do and I've never seen pics of his car...

 

Hey Mark, no times for me yet.. By the time I got my tuning issues resolved last summer, I had to replace a couple of pistons and rings etc etc, and then I was out of time for the track.. Hopefully when the tracks open back up in a couple months I'll be able to make a few passes..

You had to have seen his car before, remember it was in CHP magazine last year... (maybe it was Hot Rod)... Pics were posted on the blowthru and jyturbo lists..

Cheers,
