does this sound like 340hp motor?i didnt think

[lit549]

they say this is 340hp at crank, i think their wronghttp://www.youtube.com/watch?v=OskfTJhOftA

[ZR1BLAZER]

sound means nothing. my monte sounded more aggresive then that and i was doing ?? maybe 320 at the crank. with 13.2 @ 97mph 1/4 mile passes. melonhead and i put together a 350 TPI motor in an 83 silverado with 8.5 com that sounds meaner then what it is. dont rely on sound as a hp meter.

[lit549]

yea tell me about it, this thing sounds mean and its pretty quick but that 400 turbo is eatin alot of power.

[rayL]

did it really take 17 seconds to pull from 3k-6k?

[spacecadet]

Have to agree it s sounds good!!!

sounds good man ! Cant wait to get mine dyno tuned.

[lit549]

man theirs always some one who wants too put ya down,put all that work into something and then just too get smartass comment.99% of people are really cool on here though,theirs guys at the track like that too but i usually have too realize that what they got probably was built with DADDYS MONEY and the machine shop built the motor and there uncle tuned it for them.lol

Keep your head up, sometimes the guys sound a little gruff, but there is a ton of helpful folks on this site, by the way, truck sounds good!

[td7172]

Whatcha got for a rear gear in that thing?

[lit549]

im running 373 richmond,12bolt rear end.moser axles and moser full spool.by the way thanx for the compliment!!

[td7172]

I was told by a friend of mine that when you do a chasis dyno, the truck is alreay in high gear when you pour the wood to it. Therefore, it takes a while for the rpm's to climb, as was the case in your video. Not science, but it sounded like a good response to me.

[gdmclnh]

td7172 is correct.

[lit549]

thanks, sounds like you know what your talking about.and it did take awile to get up there;longer than it takes when im driving on the street.

[Bakas]

Here is a couple dyno pulls I did with the old motor. Just hold it at 2 grand in high gear, stomp it, and let off @6800.

[lit549]

damn thing sounds good!! what was your numbers and what is your setup??it took mine way longer too get up there; yours got there quick.But im figuring you got way more motor than mine.Sounds mean as hell.

[Bakas]

355 pump gas tfs heads nothin special, only made 325 @ the wheels. 11.20 in the 1/4

[lit549]

youve seen my combo:i think: what am i doin wrong,is it the 400turbo or what??well i dont know guess its time too get busy on nitrous.

[td7172]

Whats a normal charge for a chasis dyno? Just a guesstimate.

[td7172]

What is your c/r and what is the max lift on your cam? Where is your timing set at?

[lit549]

what is your c/r and what is the max lift on your cam? Where is your timing set at?
my c/r is 11.5-1,532-555 lift solid and timing is 36deg.

What fuel are you running? What has ran at the track?

[lit549]

ran sunoco 118 on dyno and i have raced this motor one time-4 passes.it ran around 8.10-8.13 1/8th mile

try this it will give you an idea of around what your making. Personal opinion, your only making about 275 to the tires. The dyno says so and the e.t says so.

I wouldn't run 118 in that motor if it truly has 11.5. I would say like 100 octane would be good or a 50/50 mix of race gas/pump gas. Probably loosing a few horses there. Its been proven that hp loss can be from having too high of octane.

[lit549]

Thanks,guess ill have too face it;my motor is weak,time too build something else.

[td7172]

I was also told by my tranny guy that you'll lose 2 to 3 tenths with a 400 th trans. Didn't know that!

[copley87blaz]

sounds good to me, mine is still in my garage. lol good build how long have you been on it, the th400 uses some hp but you get its strength

[Rusty]

you could just put in a good TH350 I don't think you need that 400

[td7172]

Sell the 400, get yourself a th350 with a good rebuild in her and let her eat!!
