Fast Intentions Stage 2 TT build by MA-Motorsports.

Spooler this is very interesting. You're pretty much talking about my build. I went 10:1 with the C2 cams and a bigger turbo. Still tuning it now with Seb but you're absolutely correct with the Cams helping with spool.The 6870 spools faster than the 6266 did by a long shot. Also if I WOT in 6th gear cruising 70 I'll hit 12psi before it hits 4500rpm. I had a problem with traction for 3rd gear WOT logs but switching to R888R's solved that in short order. Just moving on to E85 on Map 1 so pretty soon we'll see how it handles boost and E85. I don't think I'll be done tuning for a bit but as soon as I amI'll be throwing it on some rollers to see where it sits. I've guessed at 800rwhp but after feeling the hits ridiculous boost I'll be content with a 750 on corn and leave it where it sits.

Interesting reading these last posts from you guys ...
I've test driven the car twice now on local roads - When the motor was 10:1 with no cam the torque came on real quick and was flat out to red line. With only a little goose on the throttle and into 3rd gear it wanted to spin the huge M/T's.
It would have been nice if the motor held together.

With the MA-M 11:1 and the JW2 cams it didn't seem that 'touchy' on the throttle.
Both test drives didn't go WOT or over 40mph but I felt the power want to come on.
Brian at MA-M did a short test drive before handing the key over to me.
I heard him lean on it when he got it on to the street in front of the shop.
It sounded good but I didn't get to see it accelerate.

The 71/63's did spool quickly.

Got an email from MA-M today and they are anxious to finish up the build.
Waiting on the 6 point Roll Bar from RPM Rollbars.
Still planning to winter it down there since the weather gets ugly up here in N.J.
The car would only be sitting till spring anyway.

I am sure they are wanting to have it completed. I have had cars sit at the shop for a while myself and the day they leave is a good day. I was glad to see them up and running and on their way. My understanding is they have a lot less space as they did before.

I have experience with this playing with my 04' 5.9 Cummins dually. Swapping turbo's and trialing 2 different cams for Hamilton Cams. It is a little different but still the same.
