TE-67 vs. TE-45A at 24 pounds of boost

[Steve]

I know that the TE-45A has more overall potential but I am curious how they compare at 24 psi of boost. Thanks

I am not sure of your question !!! But look in my signature @ my run with the 45a with low boost..

I don't doubt the potential of the 45a because I went 10.81 @ 129 mph last year with a full wieght car, ported irons, fm, and 55's and 27psi. The reason I ask is because I am planning on runing my current project on pump gas and alky and I think 24 psi is doable with a reasonable amount of timing but more will likely be pushing it. According to the guys at Limit Engineering a TE-67 should only be pushed to 24 psi which fits my needs just fine. If the power potential of a TE-67 at 24psi is near that of a TE-45a at 24 psi I don't need to upgrade because I already have a 67. Basically I don't wont to spend the extra money unless I feel that I will get a reasonable gain from upgading turbos.

I put a te 67 on my car in november and am just starting to get some things worked out. I did a lot of research before I bought it & the way I took it was that the te67 & te45a both make about the same amount of power but the 67 gets it all in by 25 psi, whereas the 45a keeps making power up to 30 plus psi. The te67 is a gt67 or pt67 with a smaller compressor housing. Precision lists the pt67 on their site as being capable of 795 hp. The smaller housing might bring that down to 750. Anyway my car doesnt seem to make any more steam above 25 psi, just like they said. Been to the track twice this year & its getting faster but now I need to work on my suspension. Went 6.98 at 99.5 spinning for 30 feet on a 1.63 60 foot.

the 67 will make a tad more at 24 PSI, about the same at 27PSi the 45A will creep away after that
