What gains should i expect from SLP lid, smooth bellows, & MAF?
All three are SLP.

Thanks,
Jonathan

 

I hope you aren't planning on paying an arm & leg for the SLP bellow!
Either get the Fernco or Air Flow Systems...
Fernco comes from Home Depot, or most hardware stores.

Good luck

No, not at all! There's an auction with all these items and it's at a good price right now. How does the SLP MAF compare to other MAF's.

Thanks again,
Jonathan

 

hm....maybe around 10 RWHP...i dont know

 

I'd say more like around to 12-16 rwhp, as long as the maf ends don't lean you out and give you knock.

 

SLP has a new version of their smooth bellows that does not kink when installed. It is designed better and is expected to be available in March or April. Just what I am told. I have seen an image of it and I will definitely pick one up when it is available. But that's just me.

 

Honestly I believe the smooth belows doesn't give you any hp. A while back they did a before and after with the regular vs the smooth(er) bellows in gmhtp. And if I remember correctly they picked up virtually nothing with it.

 

You'll get anywhere from 10-15rwhp from the lid, the bellow and MAF won't do anything. MAF's CAN increase HP, but not until numbers are above 400hp @ the flywheel, even then the benefits are slight (5 or 7rwhp) Good luck though with a better breathing F-Bod!!!

Actually people have seen 5-7rwhp gains from porting out the maf on a bolt on car, while other have lost horsepower due to knock. The ported ends tend to lean the motor out a little with the ls1s, so if you are running a little rich for whatever reason then you'll some additional horsepower come of it. However if your running stoich or a little lean then the extra leaning out that the ends will cause can give you detonation causing the motor to have to retard timing, thus killing your horsepower

 

I don't think the MAF and ends really do much unless you have a cam or something. I wouldn't expect a big gain from all that. Friend of mine ran a 13.006 in his bone stock WS6, and once he got a lid, cutout, maf ends (not a new maf, just ends) and a hi-flow bellow, he knocked off .1 seconds.... so it coulda easily done nothing... intake and exhaust benefit a lot more from a modified engine then they will with stock cam/heads.
