Is that an old sling shot dragster?

It's an altered dragster originally built by Spitzer in 1987.
It has a 1923 Model T fiberglass body.
Chromoly chassis, 4-link rear suspension, rack and pinion steering, 4 wheel disc brakes, weighs 1420 pounds without driver.
Has NHRA chassis certification to run as fast a 6.00 in quarter mile.
Previous owner ran 7.9 @ 185.
I'm starting off slower, probably high 9's, until I get a hang of it and modify the engine further or install a different engine.
Here's a picture of the whole car.

Today I wired the pump and tested for 1 second and heard metal scraping!
I removed the pump and noticed very minor damage to the impeller blades and corresponding location in pump housing (see below photo of impeller blades).
I measured the clearance between the impeller and the CSR motor housing with feeler gauges and it varies from 0.033" to 0.049".
The scraping in the water pump housing corresponds to the higher locations of the CSR impeller/housing clearance.
I'll do some minor grinding with a dremel tool to add clearance in the housing and to deburr the impeller blades and I'll try running it again.

And check for balance?

CSR EWP seems like too much trouble!

I ended up just using a small hand file to deburr the impeller blades.
I only removed a hair off the corner of each blade, so I'm not worried about it being out of balance.

might be better to clearance the wp housing, in case you need to replace the pump. Do you have enough clearance for expansion due to heat?

Well I made a run last week, 6.275 @ 109 in the 1/8 mile and everything worked great, no leaks or other issues.
It was a cool day (65 F) and the highest temperature I saw on the water temp gauge was about 170 F.

CSR requires grinding positional slots in the housing, not the actual pump.

RatSSled was commenting on the fact that I had to do some deburring on the impeller of the pump - see post # 22.

Great write-up. And a killer car for the LT1!

Ran quarter mile test and tune at Zmax Dragway in Concord, NC yesterday - 9.888 @ 136 mph - just floored it off idle, didn't use transbrake yet - 70 degrees outside, water temperature never went above 165.

So I'm looking to do the Mezier water upgrade and I can't find the seal that going on the pump "GM 10128329". Is there an updated part number?

 

[Sinister]

Why do you need to "find it"? The pump comes with a new o-ring to install it.

The Meziere water pump I bought from summit came with the seal.

I saw a video online on the upgrade and it said the seal didn’t come with it. I just ordered it from Summit today so I guess I’ll see you in a couple days. Thanks for the update.

Do you have any recommendations on a wiring harness for it?

I bought the one Meziere makes. I think it was $30. It hooked up perfectly. I used a spot in the fuse box under the hood passenger side. To wire the relay. I don’t remember exactly which fuse place/wire I used. But I used the directions in a write up found on the forum.

Thanks for the update but I found a waterproof relay kit on Painless Performance. It looks a lot better than the one on Meziere and it’s cheaper.
