Here's a comparable one out of my log book, on the day that I switched to 24# injectors as a matter of fact.
60' 1.697
330' 5.245
660' 8.169
660' 80.68
990' 10.773
1320' 12.911
1320' 105.48
Actually my runs on either side of this one were 108 and 107.6 mph so this one was a little off on mph, but up through the 330' our ETs compare pretty well but then I start to pull you with the HP. But I still think that you're loosing some in the top end charge. Remember that torque gets you moving while the HP drives you out the back door. My car weighed in at 3325# on that run with unported GT-40 irons and an E303 cam with shorty headers.
I never was great on the T5; that's why I've switched over to the AOD. Get one of these cars moving into the low twelves and if you're slow on the stick like me, you start breakin' T5's.
I still say it'd be worth the try if you could borrow some 24# from someone for a few runs. You never know. If you turned around and punched out a 12.70@108+ you'd probably be kissing those injectors.
