Logical1 Posted April 26, 2011 Report Share Posted April 26, 2011 That's not necessarily a good thing. You could do the same thing with a moderate case of food poisoning and a potato in your butthole. LOL, Good stuff in this thread ;) Link to comment
philcas1987 Posted April 26, 2011 Report Share Posted April 26, 2011 You guys should shut the fuck up!!! He's doing what he loves to do. Trial and error my friends. You guys should look at the rides here on ratsun. Cobbled together piece of shits. Let alone some peoples skills. Can't wire up a matchbox. Or ir alternator. Tune a weber dgv. Even tighten lug nuts. Lol. The list goes on and on.We don't give them shit. We say yeah I'll show you how. This whole thread is clown shoes. Even my opinion 2 Link to comment
bananahamuck Posted April 26, 2011 Report Share Posted April 26, 2011 Hello im kinda new to turbocharging and was wondering if what size blow off valve i would have to run with this new turbo i just purchased ? Im running a stock 1600 so it should be able to handle the extra 16,000 whores power,, what do you guys think.. Link to comment

Stfwells Posted April 27, 2011 Report Share Posted April 27, 2011 what the hell kind of hotside is that on the turbo? I'm pretty sure it's an old Garrett set-up from the 7.3 Powerstroke. Link to comment

Nailed it It's running on wayyyyyyy too much boost. It'll probably end up destroyed pretty soon. Link to comment
datsunfreak Posted April 27, 2011 Report Share Posted April 27, 2011 It produces 19PSI under light revs in neutral Something is wrong there. That is not what is supposed to happen. :huh: Link to comment
datsunfreak Posted April 27, 2011 Report Share Posted April 27, 2011 Pretty sure on any dyno chart the HP and torque should be the same at 5252rpm??? :huh: Yeah, it's just an odd looking arrangement. Think I have another graphing the two runs. This is a bit more readable. Link to comment
Stfwells Posted April 27, 2011 Report Share Posted April 27, 2011 Georgia engineering? :huh: This aggression will not stand...man! True Georgia engineering: Link to comment
Skib Posted April 27, 2011 Report Share Posted April 27, 2011 IDK man......... I see alot of Arizona stuff on there :lol: but srsly :mellow: I need to go clean up now... Link to comment

metalmonkey47 Posted April 27, 2011 Author Report Share Posted April 27, 2011 Something is wrong there. That is not what is supposed to happen. :huh: Really? Under rev in neutral and no load it won't produce max boost? I don't know F/I And that is very evident. Link to comment
datrod Posted April 27, 2011 Report Share Posted April 27, 2011 :rofl: :rofl: :rofl: That was good for a laugh :lol: :rofl: Link to comment
SyCK Posted April 27, 2011 Report Share Posted April 27, 2011 Really? Under rev in neutral and no load it won't produce max boost? I don't know F/I And that is very evident. Boost is created under engine load, you shouldn't see anything positive while in neutral. Link to comment
HRH Posted April 27, 2011 Report Share Posted April 27, 2011 Pretty sure on any dyno chart the HP and torque should be the same at 5252rpm??? :huh: I don't think that holds the same for all dynos, particularly when their are so many variations. It was a Porsche place, so it should be a hot damn dyno, we did a big group to get the prices down. Either way, I'm too lazy to find out, and don't care all that much. It was a reputable place, I got some numbers and proved my previous hardbody was grossly underpowered. That was way before I even understood things like compression and flow. I think the magical rpm where they cross would be more related to the size of the rollers and the mass they're trying to overcome to find out the horsepower. Clearly more engineering than I have in my head. Link to comment
metalmonkey47 Posted April 27, 2011 Author Report Share Posted April 27, 2011 I found a video of it doing a burnout Anyone interested? It's kind of crap quality tho. Link to comment

HRH Posted April 27, 2011 Report Share Posted April 27, 2011 Oh boy, now I completely lost all respect for the direction this thread is going after that video.:rofl: I should show you the one of the after autocross parties where three of our "conspirators" nosed in their cars to the lightpole and proceeded to do a triple burnout. :D Link to comment
datzenmike Posted April 27, 2011 Report Share Posted April 27, 2011 A horse power is a universal constant and is determined by the formula: Torque (in ft lbs) X Engine Speed (in RPMs) / 5252 (a mathematical constant) = HP The dyno measures the twisting power of the rear wheels (torque) and because RPMs are known, the HP can be calculated on a graph. So lets assume you are making 109 ft lbs of torque on your L20B and it does this at 5252 RPMs. Applying the formula 109 X 5252 = 656500 divide by 5252 = 109 hp. Torque ALWAYS = HP at 5252 RPMs. I totally believe your numbers but the graph is very badly plotted out. Torque is always more than the HP below 5252 RPM and always less than the HP above 5252 RPMs. A flat line for the torque will produce a HP reading that doubles with each doubling of the RPM. .

See, I knew someone smarter than myself in the engineering department of Ratsun would help me out there! :D Oh crap, I made some THICK stew and drank a beer and I'm totally feeling it. I'm surprised I can type. Think maybe I'll go put a turbo on the 510. :rofl: I kid, I kid! Link to comment

Its funny that you know that off the top of your head... I know the quadratic equation :rofl: -B+/- √B2-4AC ------------------------------------------------------------2A ^^Thats not easy to do on a forum Edited April 27, 2011 by metalmonkey47 Link to comment
