seems like a lot of work for minimal gain(over other turbos out there that are tried and tested).

Strange problem. '07 Apex mtn. custom built kit using a impulse header, gt28rs turbo(internal wastegate), custom built intercooler & piping, Hallman pro rx boost controller 3 stacked stock head gaskets & arp studs. Here's the deal. I live in WI, ie. low elevation. When I run the sled back...

Well, I can answer part of your question. Your rpm's are so low because your primary weights are too heavy. If you are only running 4-6psi you should have went with lighter base weights.

Apparently its not "flawless" if you on here complaining about fuel mileage. Listen to what they are saying, all good ideas

I built a custom k it for my Apex. If I had to do it again I'd just buy a kit. I'd say it cost about the same to do it right. Of course you can halfass it for cheaper, but getting stranded 10 miles back in the bush cause you wanted to save money isn't my cup of tea. My kit came out awsome and...

11% leakdown is not bad at all. Especially if it's the same across all 3. Also, your compression #'s seem really high for some reason. If you are not seeing bubbles in your coolant while doing the leakdown test and you are not burning oil I doubt you have a bad head gasket.

Best advise: save up for a turbo. You won't regret it.

I'm having a hard time making sense of that chart.

Does anyone know the difference between CR9E & CR9EB?

What plugs are the stock plugs anyways? Is it CR9EB or just CR9E?

Why don't you share that suggestion with everyone? People who search in the future way want to know this info too.

Just wanted your thoughts on spark plugs. This last week I was out in the Big Horns and had some starting problems with my '07 turbo Apex. It uses a Attitude fuel controller. I was using CR10EK plugs gapped to .020" It was EXTREMELY COLD this week. Friday morning- it was like -10deg, in the...

I wish, When I'm running down the trail at 50-60mph my sled holds a pretty constant 3-5psi of boost with my turbo, just drinking fuel like there is no tomarrow.

I have one on my Apex mtn. I really don't ride in WI at all anymore, but if I did I would expect to have problems. I rarely see wardens, but if I did I'd be getting a ticket for sure. Personnally, its kinda loud and annoying on the trail anyways, the deep snow muffles the sound a lot.

Perfect....Thanks!!!

I here a lot of guys talk about adjusting the C0 number. Its my undrstanding that this will adjust idle and low speed cruise fuel. Now that I'm boosted and have an Attitude controller I'd like to mess around with this a little to try and smooth it out. How do you adjust this value?ie. How do...

I just checked out that site. Looks very cool & they seem to know what they are talking about. I am definately very interested. Keep us updated!!!

Where are you getting the propane parts from?

I finally got some pics up of my custom build http://ty4stroke.com/viewtopic.php?t=89365

Unfortunately I didn't get any pics when I did my engine work. I have 3 stacked headgaskets installed and ARP headstuds. I did make some more progress yesterday and today. I'll post more pics when i get them.
