Here's some dyno results on another PAE 350Buick. This one is a very basic engine. It has .030 over stock type high compression cast pistons, right at 9.5 to 1 true compression, poston 350-114 cam which is 214 intake and 218 exhaust duration at .050, s-divider intake , 750 cfm carb, mildly ported heads with stock valves flowing right at 237 on the intake and 175 on the exhaust. the engine made 342 horsepower at 5200 rpm and over 370 torque at 4100. It ws making 300 ft/lbs of torque at 3000 rpm. It idles at 700 rpm with 15 inches of vacuum. I was hoping for 350 horsepower, have'nt really done any tuning on it, just wanted to see what it would do. Jim Burek P.A.E.ENTERPRISES
This is exactly what I'll be shooting for with my 350 in the next two years. I'd like to get the same power and prepare the engine for an ATI Supercharger. Still have plenty of parts to collect and I need to read up on some of the theory of using a supercharger, but a mid-compression engine making approximately 350 HP is what I'm shooting for. I'd like to run an ATI with intercooler and bring that up to approximately 500HP. Any recomendations? Useful site for such a build.
Here's an update. The engine has made 358 horsepower at 5400 rpm and 392 torque at 4600. Mission accomplished. And it only has 5 pulls on it! It's ready to go bye bye. Jim Burek P.A.E ENTERPRISES
Wow, that's a lot of torque to pick up with just some tuning! Where can I buy a motor just like it? - Freed
Re: Re: another 350 Buick dyno test That is good looking numbers! I'm just curious... where was the last 16hp hidden? I notice that Hp and torque peak is at a higher rpm :beer Lars
Re: Re: Re: another 350 Buick dyno test Just in playing with timing. Different engines like different set-ups on timing totals and such. Plus as the engine starts to loosen up a little, power tends to move up. Jim Burek
Wow, good numbers!:eek2: The first set of numbers were impressing, but 358 horsepower at 5400 rpm and 392 torque at 4600, that is just good numbers!:beer I guess I know where I'll be getting my next engine from:Brow: -Cody
Re: Re: Re: Re: another 350 Buick dyno test "That easy"... i was thinking "advance the cam" or something! Well, that's a god reason to do a dyno run :TU: One is able to se exact what happens if one alters this or that! Without it at least some of them 16 hp:s might never have been found! :Smarty: Don't get me wrong here, i know that Jim Burek / P.A.e ENTERPRISES got the "know how"! I'm just thinking loud about my self and the rest of "us" home wrenchers that spends hours and hours with a stopwatch and the gut feeling to get things as close as possible, and have to deal with traction and ...my oh my! Thanks Jim, you made it clear to all of us that 1HP/cubic inch is reality in a "very basic engine" ...if done right! Question: was this with headders or cast iron exh.? Lars
Hey Jim, how much would a rebuild run me... pretty much stock, o-ring the block, what ever else is neccessary for supercharging? I'm looking for about 350 hp before I supercharge it in the coming years
Re: Re: Re: Re: Re: another 350 Buick dyno test The engine was run with headers, with mufflers. The important thing with the dyno as a tool is just look at what happened with Rob's motor, if we had not been able to work with it on the dyno, he would have ended up with only about 430 to 440 horsepower. Instead , he has over 530. Jim Burek
I do NOT speak for Jim Burek, But In general getting a price on an engine build isn't likely to be given without sam questions asked and before getting "your" parts checked out ....It depends on what parts "you" deliver (If you got any and there shape) or if al parts is going to be supplied by the builder... It's usually ends up as a specific deal between "you" and the builder! :TU: I guess thats why "you" don't se many replys to the "what does it coast" questions .....o No: I therefor suggest "you" PM Jim Burec on this board or get in touch with him at http://www.paeenterprises.com/paeframe.html Lars :Comp:
well my engine is good for right now i just wanted to have an idea of how much something like that cost ?
Its hard to speak cost because of so many factors. A basic build up can cost as little as 1 grand and up. Today I dropped off some stuff at the machine shop and got to see a 44000 dollar (yep... 44 grand) sprint car motor. All that money for 850 horsepower. The thing looked really wicked with the alky injection lines and the water pump mounted right on the crank shaft. Sprint cars here in Pa. are a big thing and watching them race from the inside number one corner is like nothing else. I guess the saying holds true... if ya wanna play... you got pay... :grin:
