How much Horsepower should i expect from all bolt ons? I have a magnaflow catback. getting CA header and downpipe at the end of the month and injen once NGA gets my money...i have a 2005 Cobalt 2.2.

 

135whp/150wtq is my guess

prepare to be told that nobody can predict your gains for you!

 

thanks, im not looking for an exact number just an estimate.

 

Oh geez. I'll agree you can't accurately predict. But an Injen CAI gives you 7 WHP and Corsa Catback gives 7 WHP. You could just add from there I guess

 

165-170 at the crank, just a guess.

 

what the heck would you consider "full bolt-on," that term has never made sense to me considering you bolt on so many parts of a car

 

205 with NOS



.

 

Catback, header, downpipe, intake.

 

Well if this helps you any in my 04 Cavi. I had the Injen intake, a Pacestter header, 2.5 inch high flow cat and a 2.5 inch custom exhaust and my best time evar at the track was a
14.7.

 

yeah, it is kinda hard to estimate, i would guess 15-25hp increase, and probally 10-20 ft lbs from what ever the baseline is. i am sure if you do a seach, you might find one of the 2.2 guys dyno with bolt ons. or have you tried??

Jackalope: thats a pretty good time, did you have anything else? DR? it is possible but probally very hard to do. maybe driver mod stage 6?? haha, good time though my bro used to have a 03 cavy 2.2 w/ only an intake, it was pretty impressive for a N/A 4 banger, i dont think it was in the 14s though, maybe mid-high 15s

 

Thanks. And no that was on the stock 15' BFG's dropped to 15lbs front rears aired up to
45lbs. The car was a 5spd and I'd launch it around 2 grand so that probly helped out.

 

whats wierd is that there are cobalts out there with those mods and can only run low-mid 15s.

 

i say full bolt-ons would be a turbo, which is gonna be out here in about a week =P And the gains/price ratio is much better =P

 

Turbo isn't considered a "bolt on" modification. "Bolt ons" refer to more or less basic modifications; I/H/E.

 

I am going to guess about ten to fifteen wheel horses and about the same in torque. peak. maybe like five or eight overall.

 

Nitrous just bolts on... so its a Bolt-on


.

 

Nitrous, turbo, super charged are f/i

 

I put down 135.9 whp stock....

 

yeah, "bolt ons" are BASIC mods, not turbos or nitrous, yes those do bolt on, but its not a basic bolt on, turbos and nitrous also require you to drill and tap, turbo oil lines and the nitrous and fuel lines.

 

ill find out when i get mine dynoed right now i have a injen cai and a custom 2.25 exhaust system apperantly it does make a huge diffrence cuz when i raced my friends cobalt i was ahead of him by 3 or 4 cars

 

this is exactly my point, there is no general consensous (sp? sorry its early) on what full bolt ons is so it makes no sense to say that. how much harder is it to ask how much an intake and full exhaust will improve your car

 

yea i agree with hatrickstu. no 2 cars are going to respomd the same when it comes to "bolt ons" for example like i said before i have a injen cai and a custom 2.25 exhaust system on my 07 LS. where as my friend has a AEM cai and a DCsport exhaust on his 06 and my car appearantly outruns his. also doesnt help the fact that mine is a stick and his is a automatic. but yea theres to many factors

 

thats what i would guess 2...

 

what about a flux capacitor? think I could reach 200whp with one?

 

bolt ons=

pullies, exhaust, intake, tune, headers, intake manifold, etc. etc. really anything that isn't changing anything valvetrain wise (heads/cams) and not forced induction could be considered a bolt on.


common defenition will be full exhaust, intake, maybe throttle body, tune, short throw (stick)
