Curious to find out the most HP that you can get with bolt on accessories without serious mods to the engine.

Do you consider a turbo a bolt on? on a serious note. I'd say around 70-80 with exhaust, intake, and fuel programmer. if you found someone to regrind the cams. 85-90 possibly.

This is the 1st I've seen anything about HP on the Stryker. Does any one know the specs on Hp for the stock !304cc motor in the Stryker and if drilling the baffles increases the HP any?

If I was concerned with more HP I would go the "there's no replacement for displacement" route and start with a raider. Or buy a dodge tomahawk. lol

The number I heard was high 70's. The guys at Cobra told me they had results from someone with intake, pipes and the autotuner and it was something like an 11 hp increase...

Thats actually pretty awesome for an 88ci engine! if we could eek out 90hp... the bike would be a screamer!!

Thanks RDawg for the exact specs and Mantex Ix for some numbers to go on to help me decide if the amount of $s per hp increase is some thing I want to do.

True dat jeremy. My brother-in-law has a 1970 camero Z28 that turns out 820 hp at the back wheels. That ain't stock for sure. Just think, he's pushing more hp than a NASCAR sprint car! He can outrun everything but a gas station. It gets 7 mpg and only has a 12 gallon tank.

In this months Canadian Biker magazine they had a article on air intake. The Arlen Ness Big Sucker was their air intake they wrote about. They say that changing your air intake is the most economical and best one item change to your bike you can make to increase the HP. The Big Sucker in one case gave a 21 HP increase on a Harley Flat. As they said those are pretty impressive numbers for changing just one item. I was looking at the Hyper and Cobra air intake, but may just take another look at the Big Sucker. I believe this is the one Nyjol put on his bike. Nyjol what was your results?

I hear ya midlifecrisis. I run a 68 camaro turning out a little over 500 HP at the wheel. Its an expensive nasty little habbit. Work on it for 3 hours, drive it for 11 seconds in the quarter mile. No wonder motorcycling is rapidly becoming my new hobby. Bolt on a part in 30 minutes, ride it all day....Now that makes sense!

Hey, BTW, how do you like those V&H pipes? I love the look of them and want to put em on my Stryker after the holidays....The ol'lady put a freeze on my "toy" money until after Christmas. I guess the kids need presents more than I need pipes....or do they... ::) ;D

I have an Airaid intake system that "advertised" up to 26 hp gains... expecting noticeable results... i took it to Baydo Chevrolet got on the dyno... I went from 241hp to a whooping 244!! waaahooo... far cry from 26hp!! All said and told... most systems rarely provide more than a couple of HP's. Naturally aspirated engine HP's are pretty much regulated by the size of the carburetor or throttlebody opening... it can only suck what it can suck... If you think merely adding an air intake is going to boost your bikes HP over 10hp's (really less than 5 most likley)... you are going to be disappointed.

I'm very happy with them. Wasn't sure how I would like the blacked out pipes until I saw them on the bike. The sound is awesome. Howl when you want and not too obnoxious while crusing.

Reply to Toby, I've had my Stryker for a yr now n I've pulled the baffles n it makes a huge difference, lets just say from 60mph rolling I was at 120mph in the matter of seconds, I've currently put Vance n Hines on it bc I got hit from behind on the pipes so I decided to replace them with a name brand pipe. It's not as fast as it was with no baffles.

I don't have any numbers, but out of all the crap I've put on the bike, the EJC/Bully ECM gave me the biggest gain in the "seat of my pants dyno." And I'm with SFCMCGAN, if you expect anything over a few HP with any single part, you're in for a huge disappointment.

67 rear-wheel horsepower and 72 lb-ft of torque - measured at Dyno. Keep in mind that these modern motorcycles with fuel/air mixture carefully controlled by ECU do not benefit from mods (drilling baffles, etc.) without re-mapping fuel injection, etc. Any changes like this are likely to make you lose power rather than gain any. ;-)
P.S. I am about to go pick my brand new Stryker today!

That's why we use the fuel programmers.
