Again, everything worked perfectly and we netted a total gain of 145 horsepower and 143 ft/tq, making 668 horsepower and 639 ft/tq. I'm not horribly concerned with the hp gain, but if that gain is correct, that tells me the engine has to work pretty hard to run the fan. Anyway it was a fun and informative project. A couple of years ago I installed an electric fan and a complete set of underdriven pulley's with the aluminum brackets. The best things you can do to improve driveability, gas mileage and horsepower are an intake, tune, and electric fan kit.

I mean its enormous. By Scott Deuty - November 3, 2014. What I have seen as a HP increase on same car back to back dyno was removing mechanical WP and going to electric. REPLACE that power sucking mechanical fan with dual electric radiator fans. This was a time saving feature and made it easy to fit each fan. Concept One Pulleys The water pump was a Howard )and I lovingly refer to as "Skipper", and last but not calibrated at base the rads was not moved again. 1989 Sonic Blue LX Coupe, 349 ci, TW heads, TFS Track Heat Intake, 75mm Accufab TB, 80mm ProM, 30 lb. Upgrading to electric fans is a cool way to gain horsepower and improve gas mileage. (compression improvements)! Huge draw also but its worth it at the track, i can cool down in minutes. Dyno testing on fans, alternators and oil.....all here! the mass of the thermo-clutch up to speed. Same as dyno 5 but with full length 1-5/8" headers instead of the stock exhaust manifolds. Renowned engine builder and technical writer David Vizard turns his attention to extracting serious horsepower from small-block Chevy engines while doing it on a budget. In practice it spends very little time at high speed (1%>>). âOn a naturally-aspirated setup, we have seen a 20-25 horsepower gain with E85. The E7's made 306hp @ 5300 rpm and the GT40p's made 336hp @ 5700. get the thermo-clutch to work we heated the clutch with heat guns to We would heat it up and everything was Found inside – Page iAssessments for Sport and Athletic Performance effectively solves those problems in this practical, user-friendly guide to performance-based evaluation.

Also, there isn't an electric fan that pulls anywhere close to as much air as the stock mechanical fan and clutch. was used for the engine with no fan or accessories involved. Power gains of up to 20% (with torque gains of up to 25%) are typical for turbo petrol engines, and up to 30% more power and torque for turbo diesel models. Dyno tests show a gain of up to 17 horsepower while also improving fuel economy by replacing your stock clutch fan assembly with this dual electric fan system. REPLACE that power sucking mechanical fan with dual electric radiator fans. I don't think 10 horsepower is an unrealistic estimate of the power gain I realized. Anyone here done dyno test on this ? cheaper if you can find one. Not bad for a budget street build, but we were not done yet. The increased density of oxygen allows the car to burn more fuel while maintaining the same air-fuel ratio and producing a bigger bang, more horsepower. Back in 2003 MM&FF did a ultimate guide to 5.0 cylinder head test. Its dyno proven that electric fans give you HP. RPMS. The stock 5.0 cooling set-up is boarder-line as it is!

I converted my 2005 4.2 V6 to an e-fan setup (did a write up on this site) several years ago using a 2 speed Mark VIII fan out of a Taurus. with one fan at several differing RPMs and found that there is a performance an electric fan does not gain you any horsepower. A figure of 100% I like anything fast enough to do something stupid with. Notice the torque percentage oil was measured at a temperature during these testing cycles consistently. The Taurus fan draws a ton of amperage which will cause a bigger strain on the alternator which will demand more horsepower to operate. Steve felt that the air/fuel ratio was still a little on the conservative side and decided to warm the bottle up another 100 psi, making it 1050 psi. It seems like a black magic 5.0 electric fan is a no-brainer. The test revealed a 363.5, a slight improvement. The car has power steering, and even being underdriven , no cooling issues.
