hahaha 10 hp. the thing would fall off and suck at 3000 rpm. |

my KA24DE + SR t25 = INSTASPOOL
your briggs + RHB3 = INSTASPOOL |
Re: Can anybody id this turbo?
Relatively small turbo + relatively big engine is not stupid.
It's not about gaining lots of peak power. It's about gaining low end. Look at the diesel applications it's used in... On a Bobcat, the IHI rhb3 & rhb4 are only used to gain 6-10bhp peak. The point is that they double / triple the output at low RPM, where they need it. Diesel engines on equipment doesn't run at max horsepower rpm... They run at idle, peak torque, and anywhere in between. 2.2L N/A runs 46bhp 2.0L turbo (rhb3) runs 56bhp But the torque is doubled. The difference driving one is huge. I do it on a near daily basis much of the year. Without the turbo, you try to scrape too much, and you bog down to a stop as the hydraulic system takes too much power, or you bearly get through. With a turbo you scrape too much, you bog down & the more you bog down, the more torque you get. Since you normally only run 2/3-3/4 "bunny speed" the difference the turbo makes is flat out huuuuuuuge. You've got more power at 2/3 bunny running way less rpm on the turbo as soon as it spools, than you do at wide open bunny on the NA.. The same goes for cars... Look at Saab's single bank turbo v6. Started with a GT15, then a GT17 @ 3.75psi. It wasn't about gaining peak horsepower. It was about doubling power from the previous generation engine @ 1500rpm. There's more to FI than the "typical" honda that makes really piss-poor power output (even for i4's) while it's N/A for half it's powerband. Then *finally* get enough exhaust flowing to do something with a turbo. Anyways, ya on anything but small car engine's, all you'd be gaining with an IHI would be low end power & unless you had a really big wastegate, or simply only hooked the turbine up to a couple cylinders. It'd choke like craze. On something like a small bike, or ATV, or whatever. It'd be pretty kickass. Even if it were undersized a bit, the amount of grunt gained would be phenom. |

Re: Can anybody id this turbo?
I told my dad of this awsome plan and he thinks it's stupid....I found out that our riding mower is a 18hp not 5hp...
