Yes, and there's always the problem of different dyno readings lol. Maybe on a dyno that reads much higher than whatever the standard is, 400whp is possible?

On that note, is there a standard dyno that we're supposed to compare numbers to based on what dyno we used? My numbers were done supposedly on a mustang dyno that reads 20% or 30% lower than it's supposed to, and then numbers get recalculated from there buuut I have no idea how accurate it really is

Typically the DynoJet is the most consistent.

Ecu tek will yeild you more power with its ability to tune the vvel

I just need something other than a dry sump to spin the motor to 8,000 rpms. I found heads jun cams and ati damper, waiting on cjm manifold to come out.

mustang dynos running the FACTORY CALIBRATION read lower but the mustang can actually be calibrated to read much higher. the dynojet is locked down as far as the calibration goes.

If the parts i need are available ill either take it z1 motorsports or forged performance in GA

Yes, dynojet SAE 5th gear, period!

Most of us turbo guys dyno in 4th. The 5th gear pull is just a glory pull.

Most do regardless so they dont pull that fast of a speed but it's not a glory pull; it's the cars 1:1 so if you want to be the most accurate you need it.

My car makes more power in 5th than 4th

4th is less wear and tear on the motor -- you're looking at maybe A few more lbft of tq... 4th is fine.

Compare and contrast in detail here...

Of course and it should. That's 1:1 ratio. That in SAE is as accurate as you can be. 5th isn't cheating it's just correct.

Here's a cusotmers 4th vs 5th. The 316 vs 324 ones.

Just not a fan of doing 5th gear pulls when it isn't necessary. In no off track, and even then highly unlikely, situation should you be boosting in 5th. You're better off in 4th.

I agree. My tuner and most tune 4th then finish one off in 5th. Doing 5th also can be safer because the loads higher so the tunes not as aggressive. This can be better if you're in a real world up hill against wind you don't have to worry as much with knock etc.

Just a minor update. Just bought a used long block. It's coming together slowly but surely. Now i can build with the motor out of the car.
