The Silver Buick's well Silver Buick!

Re: The Silver Buick's well Silver Buick!

I forgot to double/final check my fuel pressure before throughly warming the car up and after two test drives. It was sitting in the 30's, so I'm guessing as BBR predicted it could definately be off. So I'm thinking further tuning it isn't really practical until I know for fact what my fuel pressure is :-\ The two test drives have been interesting, I definately have it set too lean and I need to work out the accel enrichment. Getting lean backfires way to easily :-\ But I'm happy it runs and idles. I got the IAC to work, can't find the option though to target an rpm though, maybe I mis-understood.... In any case I'll give it a go again perhaps a bit in the morning before the Silver State Tech/Car show.

I still have a long ways to go but I got it so it starts relatively easily without touching the gas pedal no matter if the engine is cold or hot. I've been putting around town and it's still a bit rough around the edges, but soon I'll take the time to smooth it all out. One funny thing, when coming to a stop and I put the clutch in the rpm's drop pretty quickly like it's stalled but it catches itself it seems at the last second at idle :o :D I'm used to that feeling when the car was cold with the Q-jet and the engine dying if I didn't feather the throttle, so I've had to break myself of the habit of going for the throttle when the rpm's are falling fast. Pretty good stuff. The Idle Air control bypass is super loud on this thing, so I think I will try adjusting the idle screw to open up the throttle blades some and have the IAC close some to see if it makes the whistle go away.

It drives - way cool... keep us updated on the trials and tribulations.

Re: The Silver Buick's well Silver Buick!

I took this quick video of it idling in the morning. I don't remember what the idle speed was when I made the video, probably around 900rpm. Tomorrow I'll open up the throttle plates some and back off the IAC to quiet it down.

Sounds like you got a Hoover upright mounted on top of that motor. Keep your hands clear.

Great work. My car still won't idle until it's about 140* even with the 850.

I know what you mean! You know that feeling when you let off the throttle before it's warmed up and the engine is going to die? That's what this feels like only at the last moment it stops dropping rpm at the proper idle. eerie.

I'd find that more annoying than it just stalling especially driving a stick. Shove it into nuetral, move left foot from clutch to brake, tap the gas pedal with the right; all while slowing down to a stop.

Luckily for me the brake pedal on my car for stops the car pretty well pushing it just to about even with my gas pedal, so my wide right foot could sit on the brake pedal and feather the gas while the left was on the clutch. But now, I don't have to feather the throttle, I just have to remember NOT to try.

Re: The Silver Buick's well Silver Buick!

how's come we never hear about all these quirky keep-alive tactics when arguing EFI versus carbs? sounds like carb guys need three feet to drive a car that's warming up!!!

;D

(way to go Randal on the EFI project!!)

Hey now, if I didn't use the Performer Intake, or if I bought the edelbrock choke adapter I wouldn't be three footin it. When I had my Centurion engine in there I didn't have that problem because the stock choke worked. Same with my friend's '68 Camaro 327 4-speed, we got the choke to work and driving it first thing in the morning was way nicer. I was too cheap to buy the choke for a temporary carb. I don't know what Rebeldryver Scott's excuse is other than changing carbs ever week, lol.

(Oh yeah, Thanks )

Re: The Silver Buick's well Silver Buick!

Only one of my carbs has a choke, or even a choke horn for that matter. It's on the Caprice. I pieced together an electric choke from all my spare parts. I can drive that car right after it starts.

Hey Randal, I finally got over to the post office to send the fuel pump thingy. Hope it works for you.

slushbox. Two feet is easy.

Ever hear of heel and toe driving (the sporty car guys used to talk about it)?

Yep, I learned heel-toe driving myself - it's for downshifting on the racetrack, not for keeping a clunker running before it's warmed up...!
