Took it out on Friday to Texas Raceway (local 1/8th mile), it was 97* at 10pm! Car went 7.1 @95 w/a 1.53 60' (still need an anti roll bar). Motor is a stock LQ9 from a 2005 Escalade w/a th350 and 4400 stall (this is in a mustang coupe btw), all it has:

1 7/8th longtubes
TSP Tsunami cam
TSP pushrods

My buddy said it sounded like it was nosing over before I shifted at around 6600 (not actually completing the shift until around 6800). On the 7.1 I short shifted 2-3 shift and it obviously didn't hurt anything. I really want a 6.9x on this combo (which in better air I think would be possible).

Where would you shift this at considering I am still running the stock 317 heads?

Here is a video btw:

I have a very similar combo as you do but in a little heavier car. I have an lq9 with a tsunami cam that is carbed with a th350 and 4000 stall. I can feel mine nosing over as well over 6600 rpms. I watch videos of mine run and can hear the difference. I try to shift mine around 6500 at the track. I don't have any dyno numbers so I am not sure where the peak power is at.

Ya, no dyno #s here either. What kind of car is yours in and what does it run?

It is in an 84 oldsmobile cutlass. It has ran a best of 7.36 @ 93 so far on a drag radial and weighs 3400 with me in it.

Thats a good time. What are you shifting at?

What did it run prior to short shifting it?

If you shifted early and it picked up ET, than you know you need to shift earlier all the time.

If you listen I only short shifted 2-3, I meant to shift 1-2 early but forgot. The other runs were around 7.2-7.3

I know, I heard that.

So you shifted early on one gear change and it picked up a tenth which tells me the 1-2 needs to be shifted a little earlier as well.

I would start shifting 200 RPM earlier each pass until the ET either doesnt change or starts slowing down.

Yea you need to bring your shifts down at least 200rpm. Try that again, and then if you want to you could get creative and try another 100-200rpm. Obviously if it picks up speed and e.t. then you know your not making power as high in the rev range as you thought.

What LSA is the tsunami ground on? And is it installed straight up? I know the specs are 233/239 iirc?

Have any of you who feel it "nosing over" after 6500rpm dyno'd your vehicle? What rocker arms are you using? Curious if it is a valvefloat issue, because that cam will pull well past 6500rpm if your valvetrain is stable!

Stock rockers, TSP 7.425 P/R's, Stock Rockers, Lunati .650 dual spring kit.

Never been on a dyno, tuned on the street w/my buddy, a wideband, and a laptop.

I have the tsunami kit from tsp with prc duals and comp pushrods. Stock rockers. I think mine may be nosing over due to jetting in my carb. Mine is installed straight up as well. I try to shift around 6500 with my th350. The car has never been on a dyno.
