i went with the 1.5 housing
Let us know how it works out. I have a 1.0 G-trim on my 403" methanol LsX and it spools really fast and was thinking about a 1.32 when I really lean on it.

I got a 454sbf on e98 with 2.5in crossovers with a 106mm 1.0 ar housing and it was tough to spool to 3800 with a chance convertor. Went deep 4s no problems.

I think a 1.5 is too big. I can barely spool the 118 with a 1.32

im looking to run the texas invitational, rolling start. if its slow to spool I may hit it with a small 50-75hp shot.

A 4.25 stroke with 2.5 crossover should spool near instant.

I think the same thing....4" stoke had little issues getting a 1.32 lit off on gas.

Our Neal headed 401" sbf had alittle problem getting a 1.32 spooled but playing in the tune fixed that Shit right up. We been 4.60's with the 1.32 on our billet 94.

Qwik-SN95. What did you end up doing with the tune to get it to react in the end? I am a bit worried that my bolt together NC converter may be tough to spool also. 427 (4.0 stroke) with a 101mm and 1.32 a/r. On gas.

My 417" LS engine with a 1.32 housing works great. And the converter is the most important pant in getting everything to work together. I thought about trying a 1.5 housing but I can't get all I have now to go down the track so I don't need anymore power on the big end... And 1 3/4" headers with a 2.5" crossover for the win.
