More HorsePower Out Of My Cobalt?
408985
GM has brought out 2 different kits to up the horsepower on the Cobalts. Check with your local dealership (they have just now became available).  1 of them includes a SuperCharger.\nHypertech has a great program for the Cobalt but you have to remove the factory GM program & the Hypertech computer installs its' own program.\nThe GM kit is probably the safest bet, though. Since it has been designed specifically for the Cobalt.\nGood choice for a vehicle. I have always been a fan of the Cavalier & the Cobalt is nothing but a body style change. It is built off of the Cavalier platform & they did pretty much prefect it.\nExcellent choice for a vehicle to play around with.

a 383 is a stroked 350....a stroked engine makes alot more torque there for needing to change gears less you can pretty much run the same gear around the whole track

hi  I know that a 318 is a Dodge engine that has a good rep. I have not heard of a 340, in Dodge I beleive the next size is 360. You will get more power from 360 but it may drink more gas. Hope this helps.

Most gains are overestimated by people.  You have to remeber if making the intake slightly bigger was going to give you a lot of power, most manufactures this day could easily make their intake tube bigger for slightly more per car, if itmade a noticable differnce, tehy would.\n\nEven these days factory exhaust are much bett erthen they used to be.  There was a time when you could easily put an aftermarket exhaust on and gain 10-20hpo, but today, the gains are small, and often only their when the engine has been heavily modified\n\nWorse yet, those power numbers they tell you, are often only at one spot in the rpm curve, so it will not be a continuous gain of power, sometimes they will even loose power on the low end to report a power gain at the top end, which depending on what you do cna be good or bad.  But generally on teh street, low end power is wher it is at, thats what pushes you into your seat when you punch it at a light.\n\n(this is part of the reason you can oversize your exhaust and loose power, removing cats will often loose enough back pressure to acctualy hurt the low end power, my dad gutted the cats on his 88 mustang GT, lost all it's low end power, it didn't take him long to find a nother set of stock cats to swap back in)\n\nCheck out some forums for your car, find what real people have done to their car, and what really works, you may be suprised at what cheap things work, and how many things really don't

I have a 72 monte (currently in restoration) and the new ones are CRAP compared to the old ones.  I have a friend who just traded in a 02 ? Monte because the trans was starting to slip.  I love chevys dont get me wrong, but if the stang is a V8 it is better as far as construction and life after miles is concerned.  As for the women thing, I see a lot of chicks driving mustangs, so if you get the stang you better trick it out if you want to stand apart from the ladies.  The monte has sexy lines, but the mechanical soundness is a turnoff.  (Dont pull up on a girl and try to talk to her if she cant hear you over the rattle under the hood) Go old school, chicks really dig that.

A good high performance carb would be a holley . you can get them at a few auto parts stores or you can order them online at Jegs or Summit racing.

Chevy Cobalt\n\nThey are so cute! Cheap too!

Eliminating backpressure in an exhaust system always creates more horsepower and more torque. Headers are excellent. The more efficient the exhaust system, the greater the power gains. \n\nThere are lots and lots of good brands of mufflers, catalytic convertors, and headers out there. In terms of mufflers, some of the best ones are: Flowmaster, Borla, Corsa, Hooker, etc. \n\nThere are lots of ways to increase performance, mate. Use high quality spark plugs, and spark plug wires. MSD ignition creates a more powerful spark, as well. Synthetic oils for the engine can also add power. Get a nice tune up using high quality parts. \n\nGood luck.

A standard 22-250 is pretty fast as is.  I would just go with the fastest factory load you can find.

Cams can increase horsepower, flatten the band (torque), create a peaky band, lower or rais the peak (in RPM).\n\nWitht the many questions you have, the real answer is what works best....Most of them work in concert with each other.  Putting a big cam in without other mods will hurt performance...best this to do is set a goal for what you want the car to do and then work to acheive that with a smart package of parts, not just one.  If you don't have the money to do that, then get a better exhaust, then start upgrading the electronics (depending on the car), etc

You better find out if your transmission can handle the extra power your planning on adding with that turbo.  I would suggest you do more research on this before you buy it.

If u dont like modification, buy Subaru. \nIf u want more, buy evo8. \nI read, subaru only can reaches 550 HP in Prodrive Support, fully modified, but Evo8 in Rally Art can reaches 678 HP and If u want to use Mivec Engine, it can be more than 720 HP. It's up to u

Go tall it not only gives you more low end torque but adds horses in the entire power band. Not to mention if you get one thats ported it helps atomize the air/fuel mixture giving you better efficiency and power.

I have put a T3/T4 Hybrid on a 99 GS and to be honest, it's not smart to do unless your doing your fuel system and pistons. You would get 6psi max without blowing anything up so you would be basically be doing it for the sound of the air being vented to the atomsphere. If your gonna go turbo, your better off gettin a turbo motor (4G63T) and building from there. Good Luck Bro

Mustang for sure.  easy to tweak.  whatever you get, throw in a nitrous kit in the trunk and you'll be flying like John Denver

You should size the turbos based on your horsepower goal:\n\nA turbo helps support about 1 horsepower per 1.345 cfm airflow (that the turbo is rated at). Take the cfm rating of the turbo you are considering and multiply by two (to get the total cfm provided by the two turbos).\n\n\n----\n\nWhat I referred to was the cfm ratings of the turbos themselves. Those are usually specified by the turbo manufacturer in the form of a compressor map. The 1.345 figure I gave is the most commonly quoted estimated. For example, if you wanted a 250hp car, you would need one or more turbos rated a combined 336 cfm.\n\nAnother factor is making sure you have enough exhaust flow to spool the turbos quickly. In other words, don't oversize the turbos or the turbo response will not happen until a high rpm, thus reducing drivability somewhat.
