$1000 in motor work you only gained 14 hp??? That seems low to me considering it has 21 hp stock . Whats that alba 400 kit get ya? its just shy of $1000 after core charge . I figured that and a pipe and filter youd be lookin more like 40 or so?? No, damn Im wasting my time!
Add up the numbers... MY pipe and filter were good for at the most maybe 5-6, thats 300 dollars spent. Webcam and TIT springs was good for maybe 3 horses, thats near 200 bucks for those. Arias piston and .20 over bore were good for maybe 1-2 horses, thats another 200. Edelbrock with all other parts was worth maybe 5 horsepower, thats 400 bucks.
Total amount in money spent- 1100, thats not counting all the misc parts i had to replace.
Total est. horsepower gain- 14-16 horses.
Sad but true for the most part. The only thing left to do to the motor is porting, dyna ignition, some other minor things. For the price of a good port i cant justify spending the money for maybe 1-2 horses. If i do anything else to the motor it will be a dyna igntion just because of the tuing. Now im talking keep it on the stock bore, if i stroked it theres a whole new alley of power there.
Even with the 400 stroker kit, with no porting, no edelbrock or equal carb upgrade, no ignition... etc. Id say you would be lucky to touch 40, actually id estimate anything between 30-40
These are just esitmations, you have to consider, a stock 400 ex has around 25-28 horsepower, and a stock yfz comes in right around or over 40. If you are getting over 30 horses from a warrior you will be able to stay with most all sport quads to a point.
