i was thinking about getting this under drive pulley system. i was just wondering if anyone else has done this to their car?? is it worth while and dose it really add 10-15hp?? i found it for 70$

Not worth it. Because the LT1 water pump is not driven off the serpentine belt/pulley, the major component of HP saving is not present. Here's an actual dyno test that showed an improvement of 0.7 peak HP........

You are also likely to end up with charging problems at idle in heavy traffic, lights on, etc.

 

haha 0.7hp im glad you told me that thanks! is changing the throttle body on these cars hard/easy to do? i went to a car show last night and a guy told me he had a hard time doing it because their is coolant lines going into the throttle body. i was looking at getting this throttle body....

I bought one before that dyno was put on the internet, it was the March and it was 30 percent underdriven. The only thing I noticed from it was the belt squeek went away on the 2nd to 3rd gear shift....lol

 

Most of us find a .1 gain in removing the serpentine belt entirely at the track, so it stands to reason that just underdriving would gain you far less than that.

 

Another poor choice. There is absolutely nothing to be gained from putting a 58mm throttle body on a virtually stock engine. We did engine dyno testing on my stroker, and the 58mm throttle body was able to supply all the air the engine could use when it was only 77% open. And that was with the engine close to 500 flywheel HP.

The best thing to do is remove the coolant from the throttle body. Pull the 2 hoses off and hook them together with a 3/8" hose barb and a couple clamps. 6 rwHP, dyno proven, virtually free. Be carefull not to drip coolant on the Optispark distributor. Same source:

ok great glad i asked again thanks alot again

 

ok i feel stupid for asking this but... i cant find those two coolant lines everyone is talking about i found a former thred about this same thing

but i still cant find those two lines i found this....




are those two red niples the lines everyone is talking about? and if they are what do i do connect the two? if they aren't where are they haha

 

Most people that post on this subject have no clue, I have them.

 

Yours has already been bypassed. It looks like your intake elbow is in bad shape. I would replace it. You should get a tune,it would be better the the chip you have.

 

what kind of tune are we talkin? a dyno tune? or a programmer tune?

 

YOu dont really need a dyno tune at your level. But it would still work. Since you have a 93 you need a new eprom chip burned.
