Art,

The picture on the right in the below post shows the completed motor and blower:

Very nice setup... you'll love those MT drag radials. Closest thing you'll get to slicks that are DOT in my opinion...

 

Well, the car is complete. It made 722 rwhp/660 rwtq at 10 psi on 93 octane. It made 453 rwhp on the same dyno before the build.

Although it made less peak HP than I expected, it made more TQ...and has a very large overall area under the curve. I haven't seen too many tq lines like mine....almost straight across. Get this...it makes 620 rwtq at only 2,800 rpm!

I can't wait to see how this curve translates on the street. Anyway, the car leaves MTI Friday, so should be home soon. I'll dyno it on my local dyno here, where it made 443 rwhp before it left for GA. I'll post the results when I get them.

 

Congrats Scott. Amazing power at only 10psi. I wonder how that car will hook. How far up did you increase the rev limiter? Looks like it still pulls up to 7K rpm. We are all anxious to hear the 60-130 on that monster now. Good work bro.

 

Congrats! It will be fun trying to hook. Quick question, I thought you forged it? If so, why "only" 10 psi? Can't wait to see the 60-130 result...

 

Scott, GREAT numbers...do you have SAE numbers? We all know that the STD correction factor inflates the numbers. I'm assuming you are comparing SAE from before and would like to see SAE after. In any event, I bet this car screams 60-130.

Peter,

MTI only does thier dynos in STD. Their dyno in STD is well known for its accuracy.

My baseline dyno at thier shop was STD as well. I made 453 on thier dyno in STD in 75 degree GA temps. A month earlier, I made 443 on a local dyno near my house in 85 degree VA temps. So, they were about the same.

Also, I've actually made more power in SAE than I did in STD with my P-car on a dyno-dynamics dyno (30 more HP), so it can go either way, depending on conditions.

Regardless, when the car gets back here next week, I'll get a SAE dyno on the same Dynojet that I made 443 SAE on when I was stock for a comparison. I'll post the results like I always do.

Here's more info on MTI's dyno:

This guy made more power on a SAE dyno then he did on MTI's STD dyno: http://forums.corvetteforum.com/1568826633-post52.html

This guy got the same numbers on a SAE dyno as MTI's dyno: http://forums.corvetteforum.com/1567498742-post4.html

Scott -

Congrats - the car should be a monster. It sounds like it will be well worth the wait.

Will be fun to see the 60-130 #'s and 1/4 mile. Both should be very impressive.

 

Thanks, Eric. I'm really excited about seeing how she perfoms as well.

 

Scott, good info...BUT, I think you will be hard pressed to find any dyno in the United States that shows more power SAE than STD. The examples you posted show an SAE number that is equal to or more but are on a different dyno. I think the point is (and we've seen this in the Supra community for 10 years now) that you should ALWAYS use SAE numbers and I guarantee you that if you ask MTI to give your SAE numbers they will be lower than the STD numbers. STD correction is known to be the "inflated CF". I think my 822 rwhp on my Supra is actually close to 850 rwhp STD and my ISF 383 rwhp SAE is closer to 395 rwhp STD...FWIW

In any event, still great numbers and I hope to get a ride at TX2K10!

Peter,

As I'm sure you're aware, all SAE does is set the environmental parameters to 29.23 in/hg, 77 degrees, 0% humidity. If the actual conditions are better than that, SAE will read high. I've seen this first hand at a local dyno.

MTI did my baseline dyno on STD and it was right on. Since my baseline was done in STD, my post-mod dyno needed to be done in STD as well.

That said, if you read my posts from yesterday, you'll see that I already have a stock SAE Dynojet dyno from aa shop near my home (443 rwhp), and that when my car returns, I'll get a post mod SAE dyno to compare it to.

So rest easy, my friend. I'll have SAE numbers soon

 

SAE / STD -- whatever - still great numbers. Now for some real world #'s.

 

Great post Scott, that I'm looking fwd to! I think you'll get the most true sense of the increase over base dyno'ing on the same dyno (and hopefully similar conditions) and in SAE format. Thanks and keep us all updated. I'm most excited to hear about what 60-130 time your beast will achieve. We ALL know that you will get 100% out of that car...
Peter

 

Agree 100%, bro.

 

Will do, Peter.

On another note, DVH is in town and we're going to go get some dinner tonight. Would you like me to send him your love?
