Test drive after 4t65 swap....

[DOHC_tuner]

good decision not to run cause you dont want to blow it up. I would have done the same after putting so much money and time on the motor, good luck and POST A VIDEO!

[Vinalero]

It only remember me of my friend that was telling me :"If you're not breaking parts, you're not trying hard enough"

But yeah I get your point BJ, be sure of your build and tune before going all out.

[cherrington17]

is it the 30th yet? i want to hear how things went!

[Alero2k4]

Yes I still lurk on here from time to time.....can't wait to see what happens blackjack!!!!!!

[BlackJack]

Right on guys. We're getting there slowly but surely.

[AleroB888]

What is the lowest rpm point the engine drops to between the 1-2 shift at WOT?

[BlackJack]

BETWEEN the 1-2 shift....as in during shift-time?

What I meant was, the lowest recorded point on the chart graph, if using HP Tuners, after the ramp up from idle to max rpm, when it drops down somewhere between 3000 to 4000 rpm before rising up again to the 2-3 shift point.

[BlackJack]

Don't know, because I don't scan for it in that method. I use the torque reduction tables to retard spark during the shifts, and I measure what that needs to be based on comparison between OSS and ISS for clutch slippage during the 1-2 shift rather than how many RPMs.

[Trickyslick]

How are things going BJ??? Are you going to run it soon???

[BlackJack]

Looking like a 70% chance of this Friday night, as of now. Finding more expenses that I'll have to get taken care of along the way.

Like, all new tires, etc.

[Trickyslick]

Thanks keep me posted you have my number...

[BlackJack]

yup, will do

Just a thought, did you mean from redline in 1st, how much does it drop when it pops into 2nd?

If that's the case, I set the shift point at 5800 under WOT, then it shifts to 2nd and starts winding out again from around 3800 to 4000, well into boost still at that point.

[jackal2000]

only 5800?? thats weak. spin that bitch to at least 6500!

[BlackJack]

don't need to.

1. Stock bottom end and don't like rod stretch, bad for piston/valve contact
2. Stock cam, my powerband falls off right after 5800
3. Smoke most cars (including yours) before 5500 in any gear

See any reason for me to hit 6500 now?

[jackal2000]

reason 2 was good enough, but now provide me a reason for keeping the stock cam.

oh, too easy. When I run out of acceptable power, and can start getting traction between gears, I'll look into ways of making more power. Right now, doesn't look like I'll need it.

[Spilner521]

Speed based boost control. Obviously right now you probably don't need it and are happy with the amount of power you're putting out, but if you ever push for more, you can extract all the power you can out of it while still having traction in the lower gears. It's what I'll be using on my car.

[BlackJack]

Thanks. Working on an RPM triggered two-stage boost controller.

Figured I could run about 8psi to 4500 and then pump it to 15 once traction is established.
