Alberto.. Have you ever considered upgrading your turbos?y or why not..? I dont see too many if any threads about people upgrading the Greddy Turbos..

 

Nope not really. Im not a dyno queen, and the reliability of those 20G upgrades isnt that great-just ask Sharif how many he's replaced. My car has more than enough power to hit my goals, I took it to the track tonight and got a taste Info on that in MRC callout thread...

 

Hell Yeah! You can ride shot gun!

 

I think shops are starting to not recommend the 20g upgrade do to reliablity issues,

 

I wonder if anyone has considered the 19c Frank JR turbo instead of the 20g's. Back when I had an Eclipse I was considering getting one of these over the 16 and 18g turbos.

 

I'd have to agree with you after watching your cars.
Seems like plenty to me

 

Well, my new setup is done, so now Luie and I will be having a circuit track comparo between the JWT 700bb and the JWT 850bb setups. I just finishing tuning my car, to within 10whp of his.....should be interesting. we are going to Barber Motorsports Park this weekend.
Here is a vid from my last time there. I am shooting for 1:30'something.

within 10whp of his low boost? what did you finally end up running psi wise?

 

Sharif congrats on your new setup and good luck this weekend. In the vid is the co pilot an instructor or just a friend. I was watching your handwork on the steering wheel and was wondering if thats how all track racers use the steering wheel.I remember a few years ago a course instructor showed me something called shuffle steering. Are you familiar with that?

 

Thanks Coach.
The guy in the passenger was Luie (eagletanggreen)
I am familiar with shuffle steering, but I am not a fan of it, unless a turn requires you to make more than 3/4 turn of the wheel. I always keep my hands in exactly the same spot, so that if I need to do a correction, I know where straight is. I think most driving instructors agree with this strategy, but I could be wrong.

When you are driving the car near the limit, your hands are going to be very busy, so although the car will be making a smooth line, your hands will not.

 

Your hand work was very precise through out the whole vid and was very impressive.Yea shuffle steering is more for 3/4 turns, i agree. I remember a guy steering at 10 and 2 and when he took a big turn he kept his hands at 10 and 2 crossing over his body and he lost control in the turn and the steering wheel snapped back in the other direction.Needless to say that hurt I'm sure.

Once again great driving in th evid....

 

Thanks Coach. From my perspective, if I have to take my hands off the wheel to correct and shuffle, my car is SERIOUSLY out of shape. Has happened before at Caroline Motorsports Park...a little frightening, but I manage to keep it on the pavement. Here is the vid, and just fast forward to about 3:10min and you'll see what I was talking about. http://www.youtube.com/watch?v=tnav5gtL2BM

 

Sharif, great driving in that vid...

 

On most any roadcourse, I would prefer to have the 700BB kit over the new 850BB JWT TT kit as of now. But I hope we can make a little more pregress on obtaining some more "usable power" (low end, under the curve) with these 850BB's before we give up on them (atleast for road racing purposes) and go back to the 700BB's. We will just have to see I guess.

Hope you guys have fun this weekend, be safe and let me (us) know how everything went

 

Luie and I will be switching cars at some point this weekend, so we can both yet a taste for the different power bands. On the dyno, the 700bb kit spooled exactly 500rpm sooner, in terms of reaching full boost pressure. Same power, but my setup has a little bit more midrange trq at low boost.

 

Just got home! I will be leaving in the next hour down to Atlanta. See you in the morning.
Looks like weather wise we were cutting it close.

 

Yep, that is our findings exactly as well. But you know as well as I do that 500 rpm difference is HUGE in that part of the power band, Haha...Its right where you need it the most, usually. The lag is so frustrating on the track sometimes.

 

Agreed! 500rpms seems forever. We'll see very soon how hard its going to be to keep it in the sweet spot. I see only two turns at this venue were low rpms might be an issue.

 

Ouch.... weather is another one of the west coast benefits that I am thankfull for. Especially now that it is starting to cool down out here.

 

I am sure you will probably find out just how valuable that 500 rpm's is, and also probably find out that it doesn't just affect the low rpm spots, but the mid range rpm stuff is sometimes the most frustrating.....
