Is there a dyno to show how much of a hp/torque increase for a 97 subaru Impreza 2.2?

Not much horsepower gain. It adds a lot more audible boxer rumble to the exhaust. Low end torque is reduced slightly, but still worth swapping into your vehicle.

I'm not sure this header will work on the 2.2l, as there's only two exhaust ports on the engine block for a 2.2l, but there's 4 on the 2.5l. I can't confirm for a 97, but I know for the 2000, this is the case.

Any shop with an all-wheel-drive dyno should be able to let you do a before-and-after run, but it will be costly ($150-300+, depending on the shop, not including installing the header). With that in mind, I doubt that anyone has done this with the EJ22- the power difference is probably a horsepower or two average, with some minor torque loss down low, as with any performance exhaust install on a small NA engine (due to reduced exhaust back-pressure). The butt dyno will probably tell you that you've gained some power, and you should see a slight improvement in power, as well as fuel economy, but not enough to justify dynoing the car back-to-back. The nice boxer rumble is also brought out more, which is also nice. Either way, if you have an EJ22, you should enjoy its reliability- don't ruin it looking for power that isn't there- Mark W.

There are three power settings, 1. Tow 60 hp, 2. Race 80hp, 3, Extreme 100hp. I use # 2 Daily best overall shift and performance mix. Found # 3 gave best MPG when just highway driving. I have not had another programer but this made a huge improvement over stock.

Unicorn... When i bought mine i noticed a tiny bit of power increase only on the lvl 4 tune. I think they rate it at 25 hp gain, and 24 ft lb torque. The thing i really liked about it was it had firm shifts all the way through 3rd gear. Definitly going to help if your towing. But if your looking for just hp increase overall i would get a blackbear tune. Wont get number like a diesel but it will definitely help.

I felt a power difference right off the bat. Looking back on it I probably should have got the one with programmable ignition timing.

None, after running it for a while, what fealt like a gain was not, dyno showed same results a a drop in performance filter. Also mileage dropped, to 25 mpg from 29 mpg. I recently returned car back to stock, power is the same, fuel economy back up. Only positive thing about this unit is price, and sound. I had the Mopar unit, prior to this, and a K&N; as well, money wise, lesson learned just buy a K&N; replacement filter and save some time and money. On a side note if you are looking for bling and nice tone from engine, then the unit is worth it.

Need tune and upgrades the intercooler only helps with heat soak so maybe a little hp gain not much

Hi RichS&B; does not provide horse power specs. This cold air intake results in a 36% less restrictive improvement over the OEM air intake. Based on the less restrictive nature of the S&B; cold air intake you would probably see a 5 to 10 % increase in horsepower and torque. ThanksTruckCustomizers.com

I haven't come across that info, but I can tell you that I used it with no problems on a 4400 rpm TS.

What year is your truck. And depending on if you want custom tunes if your truck is pre 99 then technically without a hpop you will only have a true gain of 80hp max reguardless of injectors if it's post 99 then your hpop can handle the chip and the injectors will just add to but technically you don't "need" the injectors

It is no longer called the GT Hemi Plus, now it goes by the GT Platinum gas. They use the same model for all vehicles now that are gas operated. Go to Bully Dog's site and check your vehicle set up to see. It works wonders. You can change shift points and all. If you are looking for performance e, I would suggest adding a throttle body from thefastman.com, a cat back exhaust system, and a cold air intake. I have added more than 100 HP to my truck.

I have an '06 LJ with a 6 speed manual and 8" lift. I noticed a definite increase in power-maybe 10%. Gas mileage unfortunately stayed the same, even after exhaust and air intake tweaking.

Works well in my 95 Impreza. You need terminal adapters and a custom hold down clamp. I just cut the stock threaded rods at the bottom and rebent them. the car will start to -10 to -15. I've needed to jump at colder temps

I know that dyno they used for the hp gain is on a 2009 RAM 1500 5.7 (test sheet comes in package) I got mine for a 2011 RAM 1500 5.7 sport. Ive noticed the trucks response is much quicker not sure about how much hp I gained but I've never heard a intake system taking hp. That shouldn't happen because the setup (for any brand really) allows more air flow to your intake. Then this in return turns into more of a responsive setup. If I had to guess ... You might have a faulty airflow meter which in return isn't telling your truck to adjust to the new setup that my be the reason you fell no hp gain.

The first answer is no longer relevant. Amazon's info for this item is out of date. The new specs for the unit are 120 watts, and 280 ft. lbs of torque! This is about 10 amps. I say about since there are losses in the line and plug, and because when the car is running the voltage is higher. The new model is awesome. It takes lugs off of my 4x4 in one or two impacts, so less than 3 seconds. Two impacts on the way back on sets them just a little tight, but not so much that it would cause harm. I wouldn't dare let it hit another time!

I have a 2001 Ford F250 with the 7.3 diesel. With the watchdog I could monitor speed, RPM and turbo boost only. I already have a speedometer and a tach in the dash from ford, so only thing that was new was turbo boost. I send it back! Now I'm waiting to see how good Amazons return policy is.

Displays max rpm for a brief time after the engine is shut off. Can't remember exactly how long.

In my experience with a 2006 vic I saw a 2+ increase in mileage per gallon. But only after I stoped playing with the throttle.
