So how reliable are the new BD pump gas m8 kits?

03rmking · Feb 8, 2009

So how reliable are the BD pump gas m8 kits? I've always heard about reliable 2 stroke turbos, but have yet to truly see one. I hear good things about the new PG kits, but is it just more hype? Talk to me people. I'd add one to my m8 in a heart beat if they've turned the corner and found some reliability.

Tom... I have a couple of buddies running the BD pump gas kits on there dragons.. and i've been running the their race gas kit on my m10..

The PG kits have been working very well, there clutching specs and beginning numbers were off a bit.. however after a couple days spent doing a little tuning they have them dialed in. and havnt had a problem with them since...
I say go for it..

I put one on my M8 HCR and a friend put one on a M8 and niether one of us has had to open the hood exept to add inj. oil. The sled flat out rocks and is a blast to ride.I bought mine from Justin at Code Red. Check out his post in turbo/supercharger. He'll take care of ya.

How many miles you guys have on them?

snow_knight · Feb 8, 2009

tom..
on my race gas kit i have 700ish miles now.. on the pg dragons they have a little over 1k miles..

kraftymike · Feb 8, 2009

Nothing but smiles here

about 400 miles. Code Red has great customer service.

What I've seen they work great and haven't seen the hood opened yet, except to change a belt.

acs47x · Feb 10, 2009

im at 600 without a problem and have lowered 1 number on low psi. the ada works great. tom if you do it get the same clutching john has. its from mountain majic and its a world of difference from bd clutching, minor diffrences but perfect for turbo app. call john he can hook you up.

Send message to product tester on here. He has been doing both pump gas and race gas turbos for a long while. He Has tons of miles under His belt with turbo sleds.

I'm torn, I plan to buy either a 2009 M8 Sno Pro 162" or a 2009 M1000 Sno Pro 162" and I can't decide.

I can buy a M8 162" Sno Pro for the smokin buy of $8,000. Then I could buy a pump gas or race gas turbo for what? $5,000? So, I could have a brand new M8 turbo for maybe a hair under $13,000 plus gauges.

OR

I can buy a 2009 M1000 162" Sno Pro for the smoking deal of $10,000 at the same place. The I could add a SLP pipe for $600 and be at $10,600 plus $400 for the fuel controller so $11,000 for 192.8 hp on pump gas. I can add case and cylinder porting and be at 215 hp on pump gas for another $1000. So for $12,000 I'm at more hp than a M8 turbo but the sled weighs another 20 lbs so that may negate the extra hp?

Doesn't a pump gas turbo add a net weight gain of something like 8 lbs? If that's the case then we are only at a 12 lb difference between the M8 and the M1000.

H E L P which way to go????

Have yet to see the SLP pipe system work on M1000 much less produce the HP #s they claim. Speedwerx seems to work better. Go with the product that specializes in Cat not the one that seems to just jump on the product bandwagon. Pump gas 1000 is amazing, more HP than race gas M8 and works like a stock sled, only much faster.

But at 10,000 feet you have less pressure 10.2PSI atmospheric air pressure...by adding 6PSI at that altitude this puts you at 2 PSI above sea level (14.7PSI at sea level). The turbo makes up for that stuff. Figure a 200HP sled at 10,000ft and you can basically say it has lost air pressure and the HP drops with it. You'd be lucky to see 160HP at the crank up high with "200HP in mods". The M8 turbo will produce 200HP at all higher elevations...turbo compensates for the gain in altitude.

But, hey, this is easy. Spend $7k on a hold-over or barely used M1000 and put a pump gas turbo on it for $5-6K more. Now you are into it for $11k and have 230HP all the time and are smokin' both of them.

M8s are hot right now...the M1000 is almost cheaper to find and buy. And, the pump gas kits are just around the corner...I hear good things about Product Tester's kit. Might have to get one myself.

m8t or mod m1000

I have also pondered this, it comes down to which elevation you are going to be riding at. If you ride in the mountains i would go with the tm8 because you can just turn the boost up to always make 200 + hp. m1000 on the other hand, you port and pipe and get close to 200 hp at sea level and then go up 10000 ft and your probably at 150 hp now and heavier than the 8. You could also buy a 1200 big bore kit for the 1000 and be around 200 hp at 10000 ft but will still be heavier than the 8 as well as close to the same cost as the pump gas turbo. speedwerx now makes pipes for turbos witch will put the pump tm8 up to 225 hp at elevation, more hp for the race gas kits too. I dont have a turbo sled yet my self but when i do it will be an 8, cant decide on 153 or 162 though.

03rmking · Feb 11, 2009

For anybody looking for a good price on a M8 or 1000, get ahold of Benny's Arctic Cat in Gooding, ID. That's where I just got mine. They have a whole fleet with a few hundred miles that were used to film the AC promo vid. Basically brand new for a steal. m8 sno pros for $7400, etc

Frostbite · Feb 11, 2009

Yup, I understand the boost can go up as the elevation climbs to allow the sled to stay at 200 hp but, do you have to turn up the boost manually or is there a waste gate of some sort?

What about a blow off valve, is one needed?

Do you need EGTs and boost gauge with the turbo?

I'm a little familiar with turbos on Yamahas. They work well when they are working but, every guy I know with a turbo has a "theory" of why it's not working the way they think it should be working.

How would you rate the reliability of a two stroke M8 with a pump gas turbo to that of a ported and piped M1000? I really want a pull and go sled that I don't have to tinker with too much.

mtn_extreme · Feb 11, 2009

blow off valve, boost guage, af guage, fuel pressure guage are all included in the kit.

You won't tinker any more than you would with a bunch of mods on your m1000., but you do have to maintenance them regularly.

spoon · Feb 12, 2009

Twisted Kits come complete with all you need less the machining of the cylinders. Once setup, only maintenance is checking for leaks at clamps and level of oil in turbo tank, all other is same as normal. Pump 1000 we estimate at more than 260 HP at 5 psi. In Canada give me a call for kits and installs and in US give Shain a call or PM Product Tester here on forum.

that there is a sweat estimate!!!!

170 horse stock max....

90 horse out of 5 psi??? 18 HP per pound of boost sounds pretty impressive:face-icon-small-con

just trying to keep the numbers in the thread real

Just wondering here......

Is there a general hp increase for each pound of boost? Or is it more complicated than that?

Wheel House Motorsports · Feb 12, 2009

its not complicated, just varies a lot based on tuning, turbo sizing, and what boost increase... 5-6psi isnt the same increase as say 10-11

but generall 5-10 HP per pound is considered a reasonable amount, i have seen dyno sheets and builders putting the 260 HP more allong the line ot 10/11 PSI 5, heck no
