i had 2 other runs one with 2.6 60 ft 16.4 1/4@100.66 now this last runs what costed me i shattered my bell houseing on my 700 r4 the passenger side completely shattered and drivers sides in completly broke which the broke my drive shaft the only thing keeping my trans in my car was exhuast and tork arm my vig stall looks ok i hope what do u think broke my bell houseing all bolts where in it no crack when i put it a couple months ago when this broke i pulled a 1.9 60 ft and ran a 13.3@108.63 what do u guys think broke my bell houseing?

 

Not sure about your bell housing, but do you have any time comparison from befor you put the lt1 intake on? Just curious what kind of a gain you got from the intake itself.

 

Could be just too much power Or could be there were small cracks there before that went unnoticed. Especially if the bolts got overtorqed. Look on the bright side, now you can get a tougher bell housing and be NHRA approved
Mid 12's though, nice.

 

superram

Nice times, sorry to hear about the bell houseing. What tires were you running to cut that 1.6 60ft? Do you have any time from before the LT1 that were in the same conditions? What is your setup(heads, cam, TB, is it a stroker, gears, stall rpm)?

 

no i have no before and after lt1 intake but with the 355 tpi i had my mph were alway really high comprared to my et i now have a 383 stroker im running same cam that was in my 355 its jus 214-220 duration i will asure anyone that goes with lt1 they will like it it pulls all the way to 6000 awesome"thats where my rev limiter is" i hit rev limiter easily all the time it comes so quick i pulled my 1.6 60foots on a set of nitto drag radials the only thing done to my sus in lca by hotchkis this is my daily driver i really never expected 12.4 i have wheel hop im worried about now i think a real low 12 is possible thanks later

 

Could you please go over all the specs of your engine?? Also, what part of Ohio are you from??

 

my specs are
383 with lt1 intake
compucam 2032 roller
1.6 full roller rockers
ed wright chip "still burned for my old 350 with ltr"
373 gears
10.4-1 compression
afr 195cc heads
hooker lt headers
muffllex 4" exhaust
vig 2600 stall

this is my daily driver

 

where in OH??? also, what pistons, rods, injectors, etc. Also, do you think the car was faster with the lt1 or the superram?? Thanks

 

im not in ohio anymore im in wis now ive got the eagle cast steel crank and rod srp piston and je ring im running injectors fron a lt1 car stock 48mm throttle body i like lt1 better i think it has more potential man reason i swap was eas of install sr sucks to much time taking on and off

 

That is a pretty cool setup. I like your exhaust setup and also the fact that you ran mid 12's on a stock 48mm TB. What is the world coming to?

I have a SR that I am going to put on and I am keeping the stock TB as well. I will be happy right now with high 12's....

I wonder when it becomes a liability though in power...

 

A stock TB!!!!!!! Yeah!!!!!


Could you show me a pic of your engine and especially the drivers side TB mount. Is your car full weight?

 

sorry i dont have any pics online yet with the lt1 intake yeah id like to know when the 48mm throttle body becomes a bottle neck
my friends were trying to tell me back when i was running high 13,s that i needed a bigger one i showed them lol yes im full wieght 3600 with me in car i run with my sub box and all in car ill have pics online soon also go fast bird talk to john millican hes got some really good pics he help me through my install i still have pics john sent me ill email em to ya if u want

 

It would be interesting to see back to back performance trials with a 48, 52, and 58 mm TB on that motor.

Im pretty sure the 48mm Is Plenty

 

I had a budy that ran low 12's on stock throttle body on motor with a 406. I just don't think the throttle body is a great deal for what little it helps. overated in my opinion

that was funny when you stated that it was a BOTTLENECK.
Not that it isn't, but I told my buddy that was an engineer when I read that. He laughed and we looked at the profile. (engineering student) I figured so

good times man, glad to see someone do that on a lt1 intake.

I'm running one on my 406. I'm running 8.55's with the combo on 275 nittos.(1/8th mile) I still have a few bugs to work out.
Your pulling about 3 miles an hour more than me. I'm fixen to install a 10" converter about 3500 stall. Thinking about shifting at 6000 instead of 5400.

I hope to get down there with you soon.
