Anyone have any experiences with the Fast EFI's on Pontiac engines they'd like to share?

I've seen this post for a while and wanted to know the same things. I ended up ordering the Holley Terminator. I will be sure o let you know the results on my 461". I lot of $$ and unknowns, so I have my fingers crossed.

Here is a important point from the article...

"If you don't have the money to spend on a good fuel-delivery system, then you should ask yourself why you are spending $2,000 on EFI only to cheap out on the most critical component in the entire system. There's a reason that the OE companies all use in-tank fuel pumps for their cars. You should, too."

I just bought one of the Quick Fuel injection systems and have just fitted it. It's not on a Pontiac though, but I am happy to post some pic's and the installation if anyone is interested.

The car is a 1965 Sunbeam Tiger. Most were built with the 260 sbf and the MKII which there were approx only 500 built had the 289.
This one has a later model 5.0L HO engine with GT40P heads a GT cam and home built headers. I think it's around 270hp.

Here is the full kit I bought. Decided on the full kit as it had all the main components I would need.

The car has a false floor on the passenger side to give the passenger a nice flat surface to rest their feet. This creates a space between the false floor and the firewall which is a perfect place to put the ECU.

The filter went in where the pump originally went and the pump went into the spare wheel well in the boot (trunk). The wheel well is not used in the Tiger as the spare lies flat on the boot floor. In the 4cyl Alpine the spare used the well.

A return line is needed so I fitted it into the rubber connecting tube which connects the filler cap to the fuel tank.

The Tiger has twin tanks in each rear guards (quarter panels). There is a vent tube from the tops of the tanks from tank to tank. I put a T fitting in here for the necessary vent.I also ran the vent tube into a home made charcoal canister to stop the garage fuel smell away.

[URL=https://imageshack.com/i/poqbRPtCj][/URL]

The two tanks are connected with a cross over tube which has a slight V shape. I made up a new cross over tube and blocked off the bottom half of the ends so fuel couldn't escape and I would always have a fuel supply to the pump.

Quite an easy install really. I didn't have to cut any holes the tanks or install a surge tank. So far the hardest part has been trying to get the rubber grommet back in the firewall.

I did have a small problem when I first started it. The MSD produces a Tac spike when you first turned the ign on. The ECU read this as the engine needing fuel and injected enough fuel for 6000rpm. A bit of help from the engineer at Quick fuel and I rewired the tac wire from the tac out on the dizzy to the neg on the coil and the problem was solved.
I still have to do some adjustments with hot starting. Sometimes it's being a bit hard to start. I will have to see if it is getting to much fuel or not enough. When running it runs very smoothly compared to the Holley it replaced.

Very nice. Back in the day I liked the Sunbeam Tigers. A fellow a few doors down from the race shop had two of them. I used to own a '67 Triumph TR4a that I came close to putting a 289 Ford in it, there was room in the engine bay and the Ford engine weighed less than the Triumph 4-cylinder engine which was nothing but a old English tractor motor :) I wanted to mimic a AC Cobra.

Side note- I just bought the components for a Holley Fuel injection system for my Trans Am.

HP EFI Universal Retrofit Kit, 4150 Throttle body.
48 lb/hr fuel injectors
Holley EFI Dual Sync distributor

I will use an existing port matched Victor intake I already have on hand. A local fellow with experience will modify and install the bungs and rails. Labor is "free", my friend John who maintains the car will do the installation and tuning. It will support the existing 660 hp combo.

A fwiw, I got a killer deal on the parts thru Paul Knippen who owns and operates Muscle Motors in Sugar Grove, Ill. He posts on the PY board.

Steve,
good luck with you EFI upgrade. Nice to have someone to do the work for you who has experiance and free is always good.
It will be interesting to see how the engine runs compared to your current set up.

I have to work out it why mine is not starting easily once warm. It nearly fires quickly but dosen't quite. May not be getting quite enough prime fuel for warm and hot starts so I will add more without getting my hands dirty.

Thanks Kiwi.

I should correct my statement, the labor is not really "free" as we are doing some horse trading :) And it's a project I wanted to do quite some time now for interest.
Although I don't expect any big gain or loss in power the EFI has the potential to produce a broader torque curve. That said, with over 600 ft.lbs torque I doubt if I will feel any small change in the seat of my pants driving. But the drivability aspects could improve slightly and it solves cold-start problems. And the occasional hot start issues in our horrid Texas summer heat. Plus I like the idea of my ignition timing being controlled by the system. My fuel system already in place will accomodate the higher pressure needed, I did that years ago.

I used the FAST EZ EFI 2.0 system on my '72 El Camino, along with the FAST Dual-Sync distributor and their ignition box/coil. I used the FAST in-tank fuel pump (along with the rest of their fuel system), and installed the pump in a Tanks Inc EFI-ready gas tank.

I like that FAST is owned by Competition Cams, a company that is not likely to go out of business anytime soon. I also like the fact that they give a lifetime warranty on their EFI systems.

The EZ is the self-learning system. I still dictated the AFR for idle, cruise, and WOT. I also controlled the initial timing, total timing, and the point where the timing curve ended, along with all aspects of the (computerized) vacuum advance. It was SUPER easy to fine-tune the system on the chassis dyno, taking about 30 seconds to change any of the variables.

The system ran flawlessly for me since the end of '14. I traded the Elky for my new project, '73 Firebird, a few weeks ago. I'll either install another EZ 2.0 system or go more aggressive and get the fully-tunable XFI system, once I get a proper motor in the Firebird :-)

P.S. SUPER cool Sunbeam Tiger, I love those!

CURRENT: '73 T/A clone, boring at the moment...
67 Firebird (sold) 11.27 @ 119.6 Feb. '05 issue HPP
69 Falcon wagon, 10.51 @ 130mph Feb. '10 issue PHR (sold)
72 Cutlass Convertible, first car, owned since '82, now with a 6.0 LS, mild, putting just under 400 hp/tq to the wheels.
