I finally got a new HMF for my 350 Raptor. I was anxious to see the results of the net gain. I have a GYTR filter and jet kit ordered but have not received them. So I put the pipe on and lowered the needle according to HMF specs and it really runs great like that. I will probably have to rejet once I put on the GYTR filter.
Of course as we all know the HMF exhaust sounds absolutely badass. It has a really deep rumble when starting. It sounds fast just sitting there. I did notice wheelies came up much easier.
But is it really faster? Time to break out the radar gun.
The first test was top speed.
Stock this time the Raptor topped out at 59 with a couple of 60 miles per hour passes. This falls in line exactly with every article I have read where the top speed of the Raptor was accurately checked and not by "My friend followed me in his XYZ and said I was doing 68". This was with outside temperature right at 100 degrees and the tires with low tire pressure. If I cranked up the tire pressure it might of squeeked another mph out of it.
With the pipe it reached 63 mph consistently. That is more than a 5% gain in top speed, which I think is pretty good for just a pipe. It consistently hit 63, which makes me think I am at the top of the gearing for the Raptor.
How about acceleration?
For this I did a shorter run to see what speed was reached at around 430 feet. To make things interesting I put the quad up against 2 "Rabbits" to get a speed comparison.
The first contender is of course the Raptor 350 with the new HMF Candy Red exhaust.
The first rabbit is our Jaguar S-type V-8. She is rated right at 300 hp with the K&N intake. This is a heavy luxury car that takes a while to get it rolling but once it gets rolling you need to hold on.
The next rabbit was my Yamaha FZX Fazer 700. Those that know the Fazer's history know what a potent street bike this is. She is all stock.
Now for the times in the short sprint.
The Raptor stock would hit 51 mph.
With the HMF exhaust it would hit 53 mph. A pretty significant gain in a sprint.
The Luxury Jag would hit 60 mph and was just begining to pull hard.
The Yamaha Fazer would hit 76 mph and was in 3rd gear.
The asphault we were on was only a week old so the car spun a little and I had to really feather the clutch to keep the Fazer from spinning the back tire.
I had fun doing the comparison. I really thought the Raptor would out pull the Jag in the short run but I guess the Jag is deceptively fast.
Anything else you guys would like me to test with the Raptor just let me know.
