Boondockers Apex side mount turbo dyno #'s

[ken_climb]

They Dyno'd a brand new production Apex last weekend at 6500' elevation. Before installing turbo system they acheived 109hp.After installing turbo system then set to 13.5lbs of boost they acheived 212hp!Thats a 98% increase! Also the injector cycle was at 80% so the max HP for stock injectors would be 250hp.
Remember, this is at 6500' elevation.If this were sea level a stock Apex would have been about 150hp and with 13.5lb's of boost would have been about 270hp.This was done using the garrett gt25 turbo which they feel is best suited for mountain riding cause of its instant spool up.
Outlaw motor sports will have a Apex side mount kit on display at The Pullyup show in Wash.

at 6500 they would be losing 19.5% at 3% per 1000ft 150hp - 19.5% 120.75 hp. looks like the apex is not making the 150 if those dyno #,s are right.

Skimming over the run sheets (over 100 runs were performed!), I see 110.8 hp stock, 161.3 @ 8 psi, 187.6hp @ 9.9 psi, 214.5hp @ 13.2psi. The air density altitude was 8500' (after factoring in temp/humidity) which gives a correction of about 25.5%. So corrected numbers would be: stock - 139hp (sled wasn't broken in yet), 8psi - 202.4hp, 10psi - 235.4hp, 13.2psi - 269.2hp, which I believe correlates well with other dynos for similar boost numbers on this engine.

edit: looks like the prototype Apex and RX1 made slightly higher numbers (3-5hp), again likely due to insufficient break-in on the new Apex.

edit2: the 8psi number might have been low due to dialing in fuel numbers - I see a later run with 171.3hp @8.2psi, 215hp corrected.

Injectors good for 250... more proof we will see a factory turbo yami?

Ken, just one more reason to go to the Puyallup show!

 

[ken_climb]

Yah I'll have to try get out there! When is the puyallup show?

Some of main benefits to boondockers system that I can see.

#1Quick instant spool up,I don't live in the Pemberton ice field where its wide open.I have to ride in super tight tree's in deep pow to get to the bowls around here so if I am boondocking through tight tree's and come up to a creek,I need to be able to crack the throttle to get the nose up fast.
#2 Cheap weight loss, Chuck the exhaust system,Boss seat for about 37lbs
#3 Not having to use a smaller fuel tank.
#4 Isolate the engine compartment from the heat from the turbo.Where the Boondockers turbo is located it looks to me like you could drop a piece of custom flashing down on the outside of the frame up to the hood and down to the belly pan for complete isolation from the engine. Add a bunch of flow through vents and looks like your good to go!
#6 On the fly adjustable fuel management with boondockers custom efi box that can also accomodate nitrous.

Do they have anything to fill the gap at the back of the sled were the stock exhaust comes out.

You could do something like this "SRXS". Or you could get a Boss seat for even more comfort and weight loss

 

[Bossman]

So they don't give you anything with the kit. Do you know how much the kits are and are they actually available, and when I say available I mean can they ship kits today.

Ken why not put on the mountain mod seat like I have or Randy/Brett has on there RX1's. Then you would have storage, and fills it down to the tunnel. It would look stock.

 

[ken_climb]

Bossman........You could leave all the plastic exhaust covers etc there and just yank the exhaust out. I'm going with a Mountain mod or Boss seat my self for another 10lb weight savings.

 

[TurboKeith]

If the stock injectors are good for 250 hp, what can you do for more hp? Are bigger injectors going to be available and will they maintain good bottom end response?

I see you loose the parking brake with this turbo kit.

I wouldn't want to get stuck on a hill :shock:

Nice numbers though, and seems to fit nice

 

[TurboCobra]

If UR going lightweight, just keep and tough elastic band hand, and stick it over the regular brake! Just don't forget to take it off, as the park brake works real well 4 that...
