Simons CPR has begun testing our g force yam charger apex and we are very impressed with what we have seen so far, over the next couple of weeks we will be posting our results. so far we have seen a 20 hp increase at the crankshaft, so where a stock apex is usually around 147-148 horsepower, we are seeing 167-168 hp consistantly on a long hard steady state pull, the powerband is very linear and will be very easy to clutch, i am currently updating my dyno software, and next week we will be continuing our testing with a power commander and exhaust modifications that should further enhance the G Force yamcharger system, after that we will be doing some track dyno evaluation, based on the power we are seeing on the engine dyno, and the power to the track that we all ready see with our simons supertune clutch kit on a stock apex, we should see around a 20 hp increase to the track over a bone stock apex. your talking a 95 track horsepower apex in trail form on pump gas with a very broad power band that cams and head porting will not be able to compete with. simons cpr very is excited to be distributing these kits for g-force because they fill a nitch between the stock apexs and boosted apexs that have previously been an all or nothing solution, when you look at the cost of a supercharger or turbo kit, and compare it to a big bore or cammed and ported apex, there really isn't a huge difference in price, however the turbos and superchargers will make way more power. granted there are problems associated with both, but for those looking for max power the pressurized solutions have been outstanding. now with the g force, yamcharger, you get a direct drive bolt on kit that appears to me will have little to no problems, and produce around 2 pounds of boost, while working well with the stock fuel system, the cost for this system is 2200.00 and is easy to install. we have already seen 20 hp gain, and i feel with a exhaust mod and some timing we will see possibly as much as 25 hp. all of our testing should be finished by the end of next week and we are currently taking orders for the yamchargers now. if anyone has any questions on this kit feel free to call me directly

p.s. I would also like to thank Kevin Boelk for donating his sled for this testing and for all the hard work he has put into helping us test this product. thanks Kevin.

I don't blame you for being skeptical, i was too... but i have been doing this for a long time, i know usable horsepower when i see it, and my engine dyno tells no tales. after the first pull it proved itself to me, the powerband is very wide and tunable, i can't wait to put it on the track dyno, and then up against another apex in a side by side run, its going to be a blast. jeff

Is there any way to see if there are any lean spots in the rpm range?? I was kinda worried that the stock fuel system couldn't keep enough fuel in the motor with the boost. I know its running good, and making power but is it causing any unseen wear or stress on the motor due to lean conditions or othewise???

I know on the original turbos they had problems because they didn't have a blow off valve and causing the turbo to stuff the motor with air and fuel when it didn't need it. Is there any type of blow off valve on this system or is it not needed with that low of boost???

Great news Jeff :-)

I'm looking forward to read more as your testing continues. Should be something to add to my bone stock Apex.

Add it out last night for a run on the new snow with the clutch kit for it from gforce sweet!!!! I had a supercharger stage 1 last year with all the bells ans whistle and there is not much difference in the pulling feeling.
You also have the same whistle sound comming out of it as the superchargers.No gauges no tinkering just put 92 octane and go waited a long time for this.I'am not saying that its the same as a supercharger but it sure feels like one at low boost.
