Just assume that it's fair to say - the latest model versions can handle 550 hp... Since that's what the CTS-V engine is rated at.

That's a good estimate. It might go 600 na as the CTS-V is supercharged.

I was curious for comparisons sake. If Mark Stielow put this unit in to support a ZR1 powerplant and that's 630hp I'm wondering what it's good up to. Seems like a sweet deal regardless.

Thanks guys.

Sorry Rob - you wouldn't believe how difficult it is to get info on new parts from GM ... I spent an entire day looking and calling for info with no luck.

I called the AC Delco tech assistance line. That is contracted out by GM to a company that performs tech work for many of the OEMs including Porsche lambo, etc. They could answer my spec info request on the part - but I would need to setup an account first - then it would cost $3.25 for each question - and $3.25 per minute for them to answer the question.

So unless Mark can provide the info from the inside - or a member with access to the info can add it - I'll have to setup an account and pay.

GM # 19207950 and ACD # M10235

I have also tried to get the name of the supply vendor for the venturi jet component used in the early C5 Fuel Sender/Jet Pump unit - but no one will give that out as it's still proprietary.... been making those since what 1998 ? So I have bought a couple used assy's off e-bay for $20 bucks and will piece meal the setup together.

Man I'm spoiled from aviation ... the supply vendor's name is right there next to the part number in the illustrated parts catalog - WITH their address and phone number.

Rant off...

I appreciate the effort but no need to pay those yahoo's for a simple answer, that's a joke. Like I said earlier I would just like some specs for comparisons sake because I am a big fan of using factory stuff in my hot rods because they are usually a lot more durable and a lot easier to get (replacements) than aftermarket.

I found a few items on "fuel surge" tanks that most of the STI and Honda guys are running. This is basically a high/low pressure system with a very small tank for the FI pump. This looks like a potential solution to the problem without having to build two separate tanks, just place inline and use a low pressure pump to feed from the main tank. Here are a couple links:

Hope this helps.

Ok, welp, I read the piece about the surge tank from Stielow, ok back to drawing board.

I appoligize for bringing back this old thread, but I was wanting to see if any headway was made on this subject?

I was thinking of doing this as well, but back to Stielow... I agree that a pump that isn't moving any fuel is not being cooled or lubricated, but in this picture below, the low-pressure, high-volume rear pump is always flowing good volume, and the the high-pressure low volume FI pump at the front is doing what it would otherwise be doing if it were just sucking gas from the regular tank and sending it all the way forward to the engine. Maybe throw cooling fins on the surge tank or a cooler on the return from the FPR, and another cooler on return from surge -> main tank... where would heating and lubrication issues come from? I'm in 4th year of mechanical so feel free to explain all "engineery like' if need be!

Thanks,
Joe
