Wastehog Posted May 20, 2010 Report Share Posted May 20, 2010 I have a few problems with the information given about the whole power thing. Electric fans and water pumps are a BAD idea. A fan only uses at max 10 hp and you will get no where near the cfm with electric as you will mechanical. If you want extra power from the fan, put a clutch on it, other then that leave the mech fan on!! Much more reliable. Besides over a certain mph your fan is useless, so the mechfan is much better. Second, electric water pump = bad idea on a DD. Race cars run electric waterumps to cool the motor faster, while they aren't racing. Mech waterpumps are much better because of the flow they provide. Their flow is variable, unlike electric. Elec can move like a mech can. Once again, mech dosen't take that much power. Third, if you're worried about turbo lag, run twins. A lot of open class type of racers run twin turbos because they spool a hella lot faster. For exampe if you're turboing a 350/5.7L you would run 2 turbos made for a 2.5L+ motor. An intercooler isn't necessary but the higher the boost you run might require one. No an intercooler isn't based on boost 100% but its a big portion. The higher the psi the more heat. If your EGT's are lower, that's more boost. The more boost the higher the octane you will need to run. I could go on all day explaining this but that's basics. I personally hate SC's on a street machine unless its show. Turbos are far more effective and efficient. Like 80% efficient. Pro chargers, SCs, blowerrs, are all least efficient then the turbo. I read somewhere, that super chargers use like 70 hp to run, but I am not to be quoted. I do know, that they need a good amount of revs to kick boost in, and at that they aren't 100% boost until a very high rpm. Personally, imho turbo is better for the money. Okay enough info for one post. I may have rambled but I hope you take some info from this. I hope to see some pictures of this beast soon. I wanna make a trip this summer to see you, Trippi and the Humma 1985 Chevy Silverado Black and Silver SBC 350/700r4 Link to comment Share on other sites More sharing options...

I wanna make a trip this summer to see you, Trippi and the Humma this can be debated all day long drag racing and daily driving its all debatable they are saying to use electronic components to free up friction on the motor to help turn extra alts every mech component that you have on the motor creates a working load on the motor witch in turn will make motor run hoter this is y ppl are saying to run electric parts as well as in turbo vs supercharger and so on sorry if im rambling lol my 94 ranger build http://www.stevemead...4-ranger-build/ Link to comment Share on other sites More sharing options...

Now after ur done I bet Steve is gonna step up too! thanks man...but there are builds on here bigger/better than both of ours put together..IMO Lol, Trip, start another topic in engines and porformance so we won't clutter your build log. Nah its cool..I'm learning a lot Guys... its a hummer... it SHOULD be able to pull all of that and be JUST fine... its not like hes going to race it... True..but I still hate when ppl pass me on the highway. you put some aftermarket brakes on it? now thats a sore subject..I just dont think they should cost that much..I almost bit the bullet today. I ordered some 16 inch wilwoods. An hour later they call me back and say that they have been upgraded and it's gonna cost another 1500..next person he talked to was my boy tone. lol..I know I need to..I know I know UGH BLUE BALLSSSSSSSSSSSSSS!!!!!!! NEED MORE PORN! I'm waiting for pics too man..it's at the upholster...but the box should be done saturday. I will give a sneak peek tho.
