DOWN-sized

[BLOWNBY]

SCHWING!!!! SCHWING!!!:D :D :D :D

The car now pulls so hard it is SCARY! :shocked: :weird: :D There is a night and day difference between the old tune with the YSi and now with the T.

Oh BTW my first pull had an A/F of 9.x. And I though that was making power then compared to the YSi. By the forth pull I added about 75rwhp increase in the 2,500-5,000 range and about 50 rwhp at the top. Definitly need a tune from the swap.

I ended up with 545-550rwhp. A/F was just under 11.5. I am guessing I am down about 50 at the tire top end from the YSI and made only ~20psi. This is my guage reading as Lidio's boost logger was not working. However, the car feels as though it has 150 more HP throughout the low band of 3,000-6,000. The YSi made about 22-23 psi at 6,600. So it probably made more at the Top. However, it feels like a DOG as compared to now.

I tried the 3.12 pulley on the T and it picked up about 30 more HP throughout the curve but leveled off at the 6,000-6,600 mark with the same ~550 rwhp as the 3.33. I beleive my valves are begining to float up there and not doing much good. Time for some new springs as they have 15,000+ miles on them.

I am heading to the track Saturday and will post times then. But I definity can feel a HUGE power increase overall with the T. I am definitly excited.:D

Well, not the 9 second pass I was hoping but best of 10.20 at 136mph and a 60' of 1.54 :weird: . I need to get the 60' thing figured out. This should definity help my times. So far my car can dyno and mph good but not E.T.???:freaks:

Overall, my time has improved nearly a 1/10th and mph has gone up about 2mph. And the car is substantially more fun to drive on the street now. So the T has been an improvement over my YSi setup thus far. Plus I am making about 3-4 psi less.

What were your 8th mile times and mph.

[BLOWNBY]

best 1/8 was 6.56 at 107mph. Average of low 6.6X at 107 mph. This should drop as well with dialing in of the suspension. Hope to see 6.4's at least.

Nice.

But you will never see me be more excited about a T-Trim over a YSi Trim.

My best is 6.22/115mph in the 1/8th.

Nice.

My best is 6.22/115mph in the 1/8th.

Hopefully I can get some better numbers this Weds.

Very few would be more excited over a smaller blower. But the YSi made 4 more pounds of boost and still had 2mph less in the 1/8 and about a 1/10 slower as well.

Weird but proven.

Since your car weighs as much as a dump truck i'd say it's running pretty good. ;)

I've been around 3450 raceweight. I run a 8.00 crank pulley and a 3.12 blower pulley.

I bet if you change your springs and take it to 6500 you will run well into the 9's.

I'm shooting for 9.3 or better next time. I'm making around 18psi, but did dyno 754rwhp with 21.5psi but it's been hard to maintain that belt tension. My combo peaks around 6600.
