Default 99 SS TB Bypass. BMR kit or home depot?

Hi guys,

Since I am gonna change the plugs, replace air filter, clean the MAF and clean the TB, might as well do a TB bypass. I am in socal, so no worries about getting too cold here.

I did the tb bypass in my lt1 by going to home depot and autozone.

Should I do the same now or just buy the bmr kit? what do you guys think?

Just buy a single piece of long hose, enough replace the stock hoses. Much cleaner, and less chances for it to leak.

^^^ agreed with above

and hello from socal also, you might want to consider porting the throttle body while you got it off.

Or don't bother at all because it makes next to no difference.

Every little next to no difference makes a difference... I would jus get the stuff from local stores also.

a piece of tubing is like $1 dude.. I'm not sure about you but it sounds like a good investment for $1 to lower the temps of incoming air by not running hot coolant through the throttle body... maybe its just me though

Can someone please tell me what size of hose and metal tube do I need to do this mod.

I did it to my LT1 years ago and already forgot.

Its been a while since I've done mine as well, but I believe I used 1/4" Fuel Line.

And don't for get to pickup a couple small worm-style hose clamps. (The ones you tighten with a screwdriver.) They provide much better clamping force than the pinch-style the factory uses. This whole mod shouldn't cost more than $2-$3.

I did the home depot mod lol. That was 5 years ago. Haven't looked back at it since.

You're not going to heat up the air by running it through a throttle body that's 4" deep at the most.

I'm really, really tempted to set up some thermocouples once my ported TB comes back just to prove the bypass mod has absolutely nothing to do with performance - it's just an engine bay cleanup mod.

Yeah OZs to LBs and all that. but we're not class racing here

If you wanna do it that's fine, I did it when I was new to this stuff. It's not anything that's going to be felt.

I don't wanna **** in anyone's soup. I had fun doin' all the little next to useless mods I don't wanna discourage anyone else from doing them

Eh, it's something to do when you're bored, and it cleans up the engine bay a tiny bit.

I've been meaning to do mine, I just haven't gotten around to it. I'll do it, along with the EGR mod, whenever I get around to sending my TB out to get ported.
