what hot side, 1.32 or 1.0 on a pt106. 427lsx, billet rod,
e85 car. mostly track with little street. reving to 7000 rpm,

 

[95mmRenegade]

1.75" headers and 2.5" crossover 1.32

 

[Green Vette]

I agree, 1.32AR

 

[06powerstroke]

thanks guys, I appreciate the help

 

[06powerstroke]

would a 1.5 be laggy?

 

[DrTurbo]

Yes it would

 

[95mmRenegade]

would a 1.5 be laggy?

On methanol, no.

 

[06powerstroke]

On methanol, no.

how about on e85 with a bunch of methonal injection? or E98? besides drag racing im looking to run the rolling start racings. would the 1.5 housing run better all around once spooled? at what point would the 1.32 choke

 

[06powerstroke]

i went with the 1.5 housing

 

[BMF_Racing]

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.

 

[slowstang101]

i went with the 1.5 housing

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

What is the rest of your combo?

 

[06powerstroke]

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.

whats the limit hp on blow thru e85? anyone make 1750-1800 or higher without an INTERCOOLER?

 

[HRGlen]

PM Dragzilla on here, he will have some good input for you too. he runs a 106mm on a 427LS

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

 

[Qwik_SN95]

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.

 

[Marbles87fox]

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.

 

[Dragzilla]

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.
