Thread: 11's... FINALLY!

Don't worry about dynoing. Your time is what counts... I think that is awesome for a t28 w/ supporting mods.

Car is moving..

Do you guys think I should get cam gears when I get some S4's?

NO, haha you wont need them, they have been proven to make the best power where they are at stock, some people worry about reversion or however you say it due to the backpressure created at high boost levels with a smaller turbo, bigger the turbo you have the less you have to worry about it, The cams will make a serious gain at 20psi on your t28, its going to be insane, your trap speed will probably go to 123mph or better easily. You will be in the mid to low 11's if you get a good launch on a well prepped track, once the weather cools off and the t28 goes on i will also be running 19-20psi on 100 octane gas though because of my higher compression, but im hoping my trap speed to top 125mph and going for around an 11.0 maybe high 10

some might say i have high goals but hey where would we be without them, your setup will be alost identical to mine other than i have S4's and will be using the s15 dual bb t28 so topend should really kick some serious butt. I ran last night on a gtech pro on the street with my slicks and mustered a 12.6@114mph with a 2.16 60ft the slicks just spun but thats on the street so yeah i wasnt expecting anything great, haha but doesnt spin like crazy through 1st and 2nd with the slicks so that really helped alot.

hmm you need to dyno it not so much for his times...but more for he can get better times so he can buy the correct size slicks..

When my T28 car was trapping 118MPH+, it dynoed at just shy of 330WHP at 20PSI.

I ran a 12.0 @ 118.9ish.

Nice 11 second runs!

Thanks. I figure her around 300whp at 15psi. I think I will see unreal gains from a set of S4 cams, plus some bc springs and retainers for a higher rev limit.

****, you have stock cams in that car? Damn, you'll be trapping over 120 with S4's!

You will see same HP that you have at this time but with lower boost level with cams springs and retainers lets say you have 330whp now at 20 psi then you will have 330whp at 15psi but you wont see 360whp out of your t28... You will need a bigger turbo to get more whp than you have at the time because your trap speeds demonstrate that you are at the limits of your turbo.. So you will have to upgrade the turbo in order to get more power just my .02

Tha makes sense. I think my trap speed will still be higher because I can stay in each gear for a longer amount of time due to the higher rev limit. I would like to only have to run 15psi.
