What are you planning to try out next, or you just gonna use another tt? I'm looking at moving from the tt and trying a carbonetics, I'm intrigued by what I've heard about the characteristics of them on the street compared to a traditional 2-way..

As always love to see some more updates!

And if you don;t know why, its because your quote here is so off the wall wrong and just plain stupid. By stupid, I mean you have no clue what you're talking about at all, and you pretend in this quote as if you do.
so much for deplomacy..lol

Talking

[QUOTE=JeffTsai;7143421]Car is only revving to 7800rpm. The dyno operator didn't set the calibration right so the rpm read a little high. That caused the torque reading to be a bit funky, but the HP readings were accurate every time.


It's a bit more than that, but that's a part of it. The more important part is the tuning, you must tune to keep the stock ecu happy. I've spent a ton of time perfecting it.


More straps. They added like 2-3 more after that one snapped lol. Granted, for a lower HP car 2-4 straps would be fine. They started off with 6 straps, and at the end we ended up having like 10 straps on the car haha.


Already on order. Going to be trying some other things to inch up on the power a bit more in the coming weeks.


I have a build thread in this (2GS) section. Search for ProjectGS and it should be one of the top few ones in the list.


Not yet, going to have to change a few things on the car before I hit the quarter. It's setup as a highway runner right now with 3.23 rear end. I'll swap in a 3.92 TRD LSD rear end with slicks to attempt the quarter. I'll probably get kicked off the track lol.


I'm going to setup the car a bit for drag this coming race season. I just don't think the chassis can run into 9's though. I might be able to dip into the 10's if I really go at it, but again this is just a street car lol.


GoPro HD2 for the high res stuff, the last few were just with my digital camera after the GoPro ran out of battery. It was recording the whole time and we were there for about 3-4 hours.


It's not too bad, power is actually pretty easily controllable in this chassis.


Already did, but I don't always have an onboard cam rolling. I was on the way home and on a separate occasions I ran into a F430 and also the 599GTB. The F430 was a joke, easily rolled past that one. The 599 put up a better fight, but I pulled away pretty good once I got into 4th gear.[/QUOTE


Aww man, that would have been fun to watch..

You're making me regret buying another Miata instead of letting you build my 2GS. I may have to fix that mistake sometime.

Lol...people are never satisfied. Will dyno again on a DynoJet to make everyone happy. BTW: It's going through a stock stall torque converter so there is not so much loss in HP.

blk&blu*j of course your car is going to read lower if you have high stall converter for that 74mm turbo. Put a 6 speed or stock stall on your car and you power will go up tremendously.

I will be at TX2K13 next month for anyone that wants to play
