Re: GPU

I'm running the same set up. I've been told 240-250hp. I can run with the 260hp SV540's anywhere they go.

GTSIO 520/550 vs reg 520 cylinders for GPU Conversion (COST?)

Hey folks, I know this is a "running dry" topic, because I've read everything I could find in SA Forum back to 2010 that relates to GTSIO 520 conversion. These forums are loaded with experience (and BS, as expected...lol), so I found most of the answers I was looking for, but this one.... Looks like...

Re: Actual power of a converted GPU to a 470

I agree with John. I've been running a 470 conversion for 10 years with the 260hp dome top pistons. I go anywhere my buddy go's with his stock SV 540 (260hp).

Re: Best Compound Leverage Snips for notching conduit?

Sorry folks, meant to say "notching conduit" with the snips. Yes Scarecrow, using them to notch conduit for better fit. What about Klein brand, they are respected in the electrical industry.

Re: Fuel pump, electrical or mechanical?

I have a ground power 470 conversion, with 260 horse dome top pistons. I have already experienced the same issues you are dealing with.... So, as expected, aircraft engines prefer 100LL avgas. You can run 93 octane pump gas, if you start to hear pinging that is an indication you should be running av...

Re: Carb questions

My 470 conversion, 260hp pistons, runs a 500 Holley with 73 jets, 6.5 power valve. Ive tried other jets and power valve sizes, this works for me.
My friend has a gtsio 520, it has a Holley 650 4 barrel on it. I personally don't like the way the 4 barrel performs on his motor.

Re: 220 burning oil?

I had a 220 ran great, but started to use oil "like crazy". After disassembly, I found previous owner had used steel oil rings on steel cylinders. Which is common on gpu's for their intended purpose, but they won't last with the higher rpm's and heat generated on the airboats. Works great for a shor...
