I would really like to see the torque figures. What boost was this at? Al, why can't you get a tach signal? Just put the pickup on the coil trigger wire. (use the smaller of the two pickups).
616whp on STD correction is probably 585-595whp on SAE (depending on weather conditions). FYI, on our FMIC I'm getting about 1psi of pressure drop across the core AND piping at 600whp.

I guess I am just lazy Martin - I use the AEM data logging when I am on the dyno so I never bothered to try to hook up the pick up. The next time I am on the Dyno - should be early next week I will make sure to hook that up so we can see the tq.


There is no doubt that your fmic is a great unit as attested by my 9.98 time slip - however - with the Gt40 and high boost it seems like it was starting to become over loaded.

It seems that the new core we both are using is better suited to larger frame turbos

 

I would appreciate it if the other manufacturers would provide info like this.... or better yet other users.

Thanks!

 

So what boost where you running when you ran those two intercoolers?

 

I belive if my memory serves me correctly that was 38 psi on the aem log - off the end of 40 psi on my gauge on the dash

 

Ok, so you made 618whp on STD correction at 38-40psi of boost with our intercooler. 618whp on STD will be only around 595-600whp SAE (depending on weather). Didn't you make 670whp SAE on our intercooler with our GT35R at only 35psi before you switched to the GT40R? Why did the horsepower go down so much with a bigger turbo and more boost?

Also I recall you recently made 650 or 660whp with the GT40R and our intercooler and there wasn't much of an improvment over the GT35R. What changed that you are now making so much less horsepower (618whp).

Anyways, at about 600whp I'm only getting about 1 to 1.5psi of pressure drop across the intercooler, piping,and throttle body. Even if you reduced that number to zero, you would not gain much over 10-15whp.

I suspect something else is wrong that the #'s don't match. Did you test for boost leaks? did you do a leakdown test? Anything else that you changed?

 

Martin - good points. I think the best way to resolve this is I will send you my data logs from the track from before and now aftter this weekend (assuming it does not blow up at the race) and we can compare the data.

This test of the intercoolers was done at a lower level of tune - less timing and richer that is why the power was down. The last thing I want to do is blow up my car testing parts.

Also - I had some fairly junky fmic pipes which are banged up and crushed and less than 2.0" so that may explain some of my pressure drop - and the possibility of boost leaks

Now I have new Buschur 3" pipes which may help this weekend also

 

You know you were responding to Tomeievo's quote and not Al's, right?

Good job Al!!!

Buschur is making his move in the aftermarket industry AGAIN. Check mate!

 

Its too bad Buscher wont be there this weekend

 

Excellent work Al, and I am enjoying the tech in this thread but.....


someone tell me which codec I need to see the vids!!! Trying to watch the with media player and I'm not getting them to work




,,,

 

Are you saving them to your drive and then playing?

Should work with the latest MP. ???

 

yep, doing that and I've got the newes MP

 

My car was faster than this on the stock turbo....look at your graph, it dies at 98 MPH!
Hey! I hope you know I'm kidding Al...good luck at Etown this weekend...I'll be rooting for a new record from you.

 

I believe it is a mpeg2 codec. you need to have some type of software dvd player installed on your pc to watch the videos. at least that is what it took for me.

 

Thanks guys for your support - come Saturday I am going to unleash a giant can of silver bullet Whoop *** ! I am either going to blow it up or make some real fast times - I am in that kind of mood.
