Best Simple Things to Upgrade For Increase HP

[jduvall24]

Hey guys just wondering some things to start out with when wanting to get your Toyota Supra running at higher Horse Power? i know Cold air and Short ram-which one seems to work better on this model supra prefer a short ram if the performance isnt to much different. Other aftermarket parts to consider?

Thanks!

Get a cone filter and get it out the engine bay or build a box around it so it don't suck in hot air

There really are no simple upgrades for the 7M-GE which net any notable power increase. Leave the intake alone and get a good fabric filter element for it (Toyota or possibly a K&N). A good one piece drive shaft will reduce the rotating mass and friction losses incurred by the incredibly heavy two piece driveshaft. Making sure the car is operating at 100%. Make sure you have the right spark plugs in, a new rotor and cap, New spark plug wires run the right octane for your driving and environment (premium isn't always best... less kinetic energy). Generally go through the FAQ section VERY thoroughly but disregard anything turbo related as somethings are not the same for naturally aspirated engines (such as running extremely large intakes and/or exhausts).

There is no way to shorten the intake enough to see any benefit and short ram intakes and much like short runners it'll negatively impact intake velocities at low loads. The 7M-GE uses modulated intake system to switch between long and short runner modes, make sure this is operating properly and call it a day. Leave the Helmholtz resonator in place too.... despite gear head cooler talk it has been well proven that it helps and if you look at it closely only and idiot would believe that it's a restriction.

Reducing the car's weight is really the biggest thing you can do but to seriously reduce the weight is a long and tiresome task.

Personally, I'd just focus on cleaning it up as much as possible and save any other money for buying a Turbo model later on.

I found this interesting video. I don't know how oem toyota compares to oem nissan but the numbers are interesting. Atleast in this case oem isn't that bad after all.

Heh.... yeah, those tests are always a kick. At best a cone filter in a box gives you the SAME performance as stock... Unless you've got a MASSIVE turbo and are sucking babies in you're not likely to significantly out flow a GOOD stock filter.

BTW - those links are both for the same video. Mind posting the other one you had intended on sharing?

I should mention that for those of you who want to test this out further and think you still can do better you can pick up a device used to measure pressure differentials across two reference channels called a manometer. Typically a good digital unit will run you in excess of $120 but you can find some which are good enough for this purpose starting around $40 on eBay. You'd measure the pressure right at the filter on the exterior and then at a reference port somewhere before the turbo or on a N/A before the throttle body. Measure at idle and then while driving around. Swap filters and repeat the last steps as closely as possible. The measurement you see on the meter represents the change in air pressure across the filter.

I corrected it and also found this one. I find it hilarious.

I love how they try to stay serious.

I love those two guys watch their videos all the time but they do know a lot about cars.
