I'm wondering about putting my ported/built head from my 06 apex on a 2011 or newer eps sled and bottom end, with an alpine front mount turbo with a 2871 garrett. I have Boost it standalone box with auxiliary injectors so the sled runs on its stock computer and has 4 injectors in the...

My tps is showing 2.4 deg .6v at idle and 76.0 3.5v wot. It should be 0 at idle and 80 wot I believe?Idle is erratic on it and doesn’t idle well when cold. Anyone have tps issues? Thanks

Shut the sled off and went to restart and its dead...no gauges, fuel pump, or clicking. I've swapped ecu, ignition, starter relay, swapped solenoids, checked fuse blocks, all fuses. I have no power at the red/white wire that plugs into the starter relay. If I run a wire from the battery to...

I'm getting the temp light and the oil can light when I let off the throttle in boost. It momentarily shuts the sled off for 1 second and then comes back to life. If I cruise at very low boost under 3psi and chop the throttle it doesn't do it. Sled runs great otherwise. There are no codes...

My apex throws a code 30 and dies and I have to restart it 4 or 5 times before it stays running when its less than 25. It was 14 degrees the other day and I had to restart it about 10 times. I run synthetic 0w30 torco oil. I'm afraid of burning up my starter and would like some ideas on what...

I have a friend with an apex and he wants a low boost 10psi turbo. He is looking at this: "This is a brand new Garrett oil/water cooled T28 turbo. (T25 hotside/ T3 cold side=A/R 48) with adjustable wastegate. This is a $1200 replacement/upgrade turbo. It flows 448 cfm! It should flow in...

I built an Impulse style 4 to 1 short tube header for my RX-1 and pulled off the Boondocker turbo parts. The old BD setup has me at 125 mains and the needle bottomed out. I know I'm going to need to richen it up and was wondering if anyone had a good starting point. Maybe start with 135's?

I'm switching my BD RX-1 over to a mid mount and I'm wondering how much intercooler fans help? I mainly ride steep and deep all day long and want to help prevent heat soak as much as I can. There is lots of wot and barely moving and the lay down i/c won't get much airflow. I'm also looking at...

Anyone know where I can find 321ss that has a .140" wall? I'm doing a mid mount on my 1ton. I found some heavy wall 304, but none in 321 when I googled it. I checked Burns stainless and a few others. Also wondering about what o.d size tubes are the best to use? I was thinking of getting a...

I bought an Boondocker '03 Rx-1 recently and on my second ride it threw the #3 rod out of the case. I was only running 12-14lbs boost with 30% 110 and 6500ft in elevation with 11.5-12 afr's. And its got a .063 headshim in it. The guy I bought it from had bought the sled as a box of parts and had...

Just wondering how the 2854 compares. My friend fried his 2860 due to a plugged oil line an;d is looking at a 2854r. I am not familiar with it so I'm wondering max psi boost.

Here goes...I helped a friend put a Boondocker kit on an 07 Apex a few months ago. It came with a Pure Logic controller and it worked for a few days then just quit...lights wouldn't work, completely died. He bought a used Fastrax box and put it on. The sled starts good and warms up idles...

I just picked up a new to me Boondocker t-rx1. I pulled the intercooler off and it is completetly blocked off with an aluminum plate across the air chambers right before it goes into the carbs. I thought I knew how these i/c's worked, but now I'm stumped. It doesn't look like any air would be...

My friend was having idle issues with his 07 Apex and started adjusting all of the brass synchronization screws and the black idle knob. Now he doesn't know where to start with putting them back. After doing some reading I found that you're not supposed to mess with the #1 screw. His sled...

Just curious where my compression ratio would be with this. It's an rx-1 so each gasket is .030. I rode a rearmount for two years and am used to the lag, so this shouldn't be as bad. The only trail riding I do is to get to the mountains. I usually ride 6-9000ft. I am going to run 50/50...

What's the difference in the i/c on an apex vs an rx-1...I'm guessing the tbi flanges are different diameter than the carbs? If so what are the diameters of both?

I've been thinking of getting rid of my old bender rear mount gt2860 kit. I found an older cpr kit for a pretty good price. I am wondering about the efficiency of the older style cpr intercooler? It looks pretty small. My bender kit has a tunnel cooler and a decent sized ic. I ride...

I just installed a boondocker turbo kit on an apex and it misses at low speeds and then takes off around 5000rpm. I cleared the codes, but it keeps showing a code 14 and 20. I bypassed the purelogic controller and nothing changed. It didn't have any codes before I put the turbo on and I...

I found a turbine tech brand header for an rx-1. Its supposed to be a replacement for cpr headers. Looks like the company is out of Canada. Just curious if anyone has tried one yet or heard of them. It says that it is schedule 40 stainless tubing.

I just put them in and it seems that the top threads for the nuts are different. I pulled the threads out of one of the nuts already. Wondering if anyone else has encountered this.
