hahaha yaw it's definatly off, the point I was trying to make is that I could tell by the seat of my pants it was quite a bit quicker I know it's not .7 sec in the quarter like my phone says that was just usless info but kinds interesting because it would test it over and over again, with similar times it would change by .3 sec when doing runs back to back. I don't want you guys thinking im putting faith into the iPhone app, like I said just some fun USLESS info! I would guess it droped my et .3 sec, Definatly helped alot more than my underdeive pulley!

 

.3 seconds is roughly 30hp...you would be lucky to drop a full 1/10 on the 1/4.

 

You don't have to believe it, but that's my guess on how much it helped me.

 

okee dokee

 

so most of you agree that this mod. does make a difference.

I need to P&P my TB!! So what tools exactly are needed to do the job??

 

A dremel, lots of sanding wheels (from coarse to fine), some sandpaper to finish it off, and about two hours. A can of compressed air helps too (those computer duster cans) b/c you will have a lot of metal shavings.

Don't remove material close to where the blade closes or you could mess up the idle by letting too much air in.

Search ls1howto.com, ls1tech.com and this forum, I remember seeing a good write-up about it.

 

^^^I appreciate the info man. I might do it this weekend.

 

No prob. Let us know how it goes! Post up if you have any questions

 

I think there was alot of attention to detail in my shaner tb that helped with power, I think if I were u I'd spend the 125 bucks on a shaner! I just don't think I would have got the same gains if I did it in my garage! But if you don't have the125 I'd say don't forget the bumpstop!

 

I've yet to see a ported TB give any real benefit on the dyno or actual gain at the track but reading this thread makes me want to start porting people's TBs for money.
