just got her dyno'd, she made 381hp and 400 ft/lb of torque, not bad for a 305 specs in signature, i took a video will post a link.

the procharger put out a max of 11#'s

381whp, 400ft*lb torque, what rpm? was it more of a peak? or was it a whole range, kinda flat? Great power, must be a great tune too. What are your AFRs?

 

it was a whole range the pull was up to 5500 rpm and the afr was 12.3 flat, i need to get it down more but i think i need bigger injectors

 

Nice numbers! I really need to get my 15psi turbo 305 dyno'd. Sept. 23rd I should have numbers.

 

Yeah i'd like to see what my car can do, I just need a clutch that will hold in 4th gear. 381hp is the same as my brother's NA 383 LT4 (in sig).

 

86Z, nice job! .. any pics of your setup? What are you guys using for internal engine components or are they still stock?

 

My internals are basically stock.
-Reman std/std crank. I bought it for a 1975 truck (or did I say 70 camaro?), looking back, it could have been a factory forged one, but I couldn't tell the difference when I built the motor and haven't seen it since, and I really doubt it.
-Speed pro pistons. Stock replacement for a 70 camaro. I was told that the compression ratio "should be a shade under nine and a half." I think he also said they were hypereutectic. I was in high school and didn't know any better when I built the motor, but it has held up this long. With the abuse I put it through for 20K miles, thats a big deal.
-I got the rods and block from the trunk of a car at my uncle's house. The casting numbers say they were from a 1975 truck or van, 4 bolt mains. I had it bored .030".

 

my engine is not stock, check signature.

 

What about pistons, rods, crank, block? Also, have you thought about using a cold air intake for the supercharger or is there not enough room?

 

yes, the block pistons and rods are stock, there is no room to really relocate the filter.

 

Ha thats awsome for a 305! I think it would be hilarious if I was driving a 383 and got beat by a little center super charged 305.

 

Nice run. It looks like you have it tuned well now. The cam seems like a good choice for that setup. Good idle and good HP and torque throughout the run.

Did you happen to record the injector pulsewidths (PW vs. RPM) when it was on the dyno? You are getting up there in HP for the 30#/hrs, but you might be able to squeeze out a little more fuel if the VE table isn't maxed out.

 

yes i did do a datalog, i've been so busy i didnt get a chance to look at it yet. i'll let you know

 

Good numbers. Are you planningto up the boost in the future?

 

no i dont plan on upping the boost with this motor, i do have a 350 on the engine stand for a replacement, that will be all forged and lower compression

 

Are you using the ATI fmu and if so how easy did you find it to use and what fuel pressure are you running at?

 

yeah i'm using the ati fmu it sucks with my application, it set to full rich, and i still needed to add fuel in the VE table, i need to switch to the 7749, i'm running 50#s fuel pressure at wot then the fmu bumps it to around 80#'s
