I would buy one proven in the real world befor I would buy one proven on a dyno, I made that mistake with my first kit from simmons cpr, they had proven it on the dyno but it didn,t work like that at 10,000 ft. in the steep and deep. each to his own.
Impulse Apex Race kit???
- Thread starter BOOSTBONER
- Start date
I think dyno numbers are about 25% and rear world in the mountains in the steep and deep is the other 75%, like winning the Big Dog Shoot Out.
haha
some of the best mods i've ever bought were the NON dyno'd mods..
RKTs 734 (before he was pushed to play the HP games)
and now Paul's Impulse kit
and quite honestly. i could care less even IF your setup has 10 (or w/e it may be) more hp on the dyno, I'll keep having a blast on mine...and knowing someone top notch is backing the product and furthering its developement to boot.
if you feel better by telling your buddies how much HPs you have, more power to ya.. we all have fun in our own way.
i'd rather just ride and have my fun that way.

I just watched Mnt. Mod Mania and that impulse turbo was very impressive.. If I already didn't have the BD turbo on my sled I would go with the Impulse.. I will be upgrading to the 2871.. And I agree with you on that Dyno #'s don't mean chit!! Like Mattymac Said PSI had dyno #'s and they were a joke.. Perfect temp. climate, all controlled. If you want to get an idea of what a Dyno would show just figure 7hp per pound.
So... 25#s @ 7hp = 175hp
stock Nytro = 135hp
Total = 300-310hp depending on your elevation
Good enough???

If it blows air into the motor it will make horse power. If the turbo kit says pounds of boost you can take a good guess at what the horsepower will be. 10 pounds about 220 230 240 depending on compression and the eficeny of your motor. it goes up from there. i dont need dyno #s to make my decisions. it is nice to see a dyno chart tho. it shows the kit producer actually put some time into it.
The impulse kit is well thought out.There has been alot of r&d in it, and besides it kicks *** in the real world so who needs a dyno if its kicking ***!!!!

Because you don't buy a 10,000 dollour kit to say i don't know how much power it makes but it works that a load of cr--p. People in the real world want to now how much hp it has not that it just works!.................. never hear of this theary but it sucks
if you want to run a turbo you should do your home work and understand how they work. and if you understand how it works and the components in the kit then as has been said you can figure out what kind of power it will make, if all you are looking for is dyno #,s then maybe a turbo isn,t for you as you obvoiusly don,t know what you are looking at.
Must be a lot people that are not from the real world buying this turbo. Paul is producing a great kit and has a HUGE demand for his product, probably far exceeding his own expectations. Little or no advertising, mostly word of mouth by many satisfied customers who have the seat time under many different riding conditions. I will take that to the bank anyday over dyno #'s and what someone claims a turbo will do without the actual "practical applications" that you get from seeing how it performs under most all situations and conditions. When you crack the throttle on one of these kits, dyno don't mean chit. I'm sure that there a few people in the "real world" who have to have numbers to justify there kit, that's cool, but for many of us, how things perform is a greater measuring stick than what some sheet of paper says.

eh, Maybe i don't know to much about components that make a good turbo kit. I am a new turbo guy running powder lites stage 2. It seams to make good power..... I just can get use to the no dyno papers on the impluse kit but it must work good the feedback is good on it! It is a pricey kit i would like to try one some time only thing i heard - about it that's it noisey because of the air intake where the gas tanks is.

agree, If the kit satisfied its custumers and they are turbo riders for awile on different set ups, different turbo kits, then its a good will put together kit.
How is the heat on them the turbo is a front mount do they heat up vs a rear mount that has snow helping the turbo stay cool?
A few flat land guys out east have dynoed 500+ hp with the tial v band turbine housing/external wastegate set-up on a rx1 motor. Pauls race kit has a lot of the same components in his turbo kit so that should give you a ball park figure. With a nearly equal length v band header, vband tial housing, 44mm external wastegate that he is using, this is the heart of being able to make huge power with excellent response.
It's gotta run significantly hotter than any rear mount however Rotax has put a ton of hot Spring rides on his impulse and it ran perfectly. The impulse kit has def created a lot of interest. In the past years there were not a lot of choices, most went with MCX because of the proven reliability and top notch support. Now their are more options out there and apparently Paul has really stepped up to the plate (never met him).
I'm on my second MCX. When I was building my turbo last season I looked at boondockers, MPI and MCX. At the time Boondockers did not have a kit on the snow and to the best of my knowledge is not really a 4stroke shop. MPI is a joke. Did not look at Impulse as last season was the first i really heard of him and wanted to give it a season to prove itself. Don't know why i didn't look at powderlites.
HP #'s are a joke esp at the altitude we ride at (park at 10k). It's like talking about dry weight

All I know is that Paul told me that it's even faster than the Nytro that won the BDS last year. So it must be the fastest set-up to date!!! Dyno numbers don't mean much, but they give you a slight idea of where the kit might place itself among others. The parts on this kit are the BEST!!! I can't wait to order mine. Should be ridiculous with that 3071
yawn...we just need snow...
lol
on the heat thing...mid mount definately gets cozy...but i may also be a bit anal about venting/holes.
i do like that the tank doesn't sit on top of the turbo, and this helps in dispersing heat greatly...and not cooking fuel.
i have pics in my profile of the venting i did on my plastics over the summer. should make a very big difference in dispersing heat.
i'm still a believer that a cooler running engine and drive train is a happier engine/drive train..and will last longer.. there are not many applications that excessive 'heat soaking' is a very good thing long term.

A turbo needs to stay hot to run efficant and make power. Why the hell would you want a cold turbo getting hit by snow ice ect.. rear mount. A mid mount or front mount keeps the heat up in the turbo and yet the air temp from the intercooler is kept down and having better performance over all not to mention less lag.Mountain testing is by far the best! You get the kit and it works in the mountains. And for those of you that are after the dyno numbers and believe it like gospel, you can make a land and sea dyno give you bigger hp and tourqe #s then what the sled really makes for guys that want to tell thier buddys of all the hp they got. And there is one turbo company that did just by running the dyno back wards. running the machine to the rev limiter and pulling it down to idle with the dyno to get the bigger curve."spiking the dyno" This will get your higher numbers because you are slowing all spinning parts and the engine down for your advantage. The dyno has to over come this mass.And also testing at sea level because thats where we all ride lol. But hey, what ever sells kits right thats what some guys want."my kit has 300 hp at 16 pounds boost"lol. Dynos are not a bad thing just dont buy a kit because of numbers. Impulse is the real deal, proven in the mountains for every day fun in the pow and winning races on the same sled.
