I'm still waiting to here back from Richard as to the ability of the kit components to cope with nitro at about 20% concentration.

I don’t want to have to replace my pump seals every 2 months, but I wont mind once a year.

 

both logs are with the 255/40's,
3rd gear pull
me and mife combined weight is 300 (she is little 105 ).
about 20-30lbs of tools in the back as well (safe than sorry)
No weight reduction.

thanks for doing this man

seals are $25 shipped but I hear you about chaning them out too often. I just need to find the carrier, i didnt quite a bit of research last year posted it up on a vendor page and now his thread is deleted.

 

$25 every 2 months is nothing...however, depending on the location of your pump...taking it out and replacing may get annoying. But, but the power!!!

where does one find the seals? link? did i hear you have to get them directly from shurflo?

 

shurflo wont sell them to you directly I have to buy it from one of there suppliers. I will did up and try to find the part number with a contact info

my pump is in my trunk LOL

we have some meth heads in the house today

Corrosivity to Non-Metals:
Nitromethane attacks some plastics, such as acrylonitrile- butadiene-styrene (ABS), chlorinated polyvinyl chloride (CPVC), nylon, polyvinyl chloride (PVC) and polyesters; elastomers, such as chloroprene, ethylene vinyl acetate (EVA), Viton, natural rubber and silicone rubbers, neoprene, niltrile buna-N (NBR), and polyurethane; and coatings, such as coal tar, epoxy polyamide and vinyls

wetted parts within a WAI system:
shurflo pump head = nylon
pump seals = epdm......some might have viton
fittings oring seal = nitrile/buna n
tubing = nylon based
seals in solenoid valves = epdm/viton/buna..

these might all need to be changed often running nitromethane depending on concentration?

 

FOUND IT google found it but not the srtforums search

it gives you a bit of info and post 2 I posted the part #'s

 

good find slow car, looks like a pump rebuild in the future LOL but we will see the gains later this afternoon thanks to dudical26

 

I am not sure I am qualified to say our HFS-xx system is compatible with nitromethane at any %. Our piston pump with PTFE seals will certainly have no problem. All fittings to have to be metal to metal compression seals. The little pump can deliver about 330cc/min. Teflon hose is recommended.

Wow, so its seems like almost the entire system may need replacing. Of course how often will depend on usage and concentration, but it seems as though nitro attacks almost all kit components.

 

Can you run metal to metal compression seals and teflon hose with the HFS kits.

I would not mind having to replace the pump seals every once in a while, but I would not want to have to change all of the other parts.

 

I have been trying to track down some Nitro near me.

It seems that most VP racing fuel suppliers do not stock this stuff. Some of the places I called will only order and entire 54 gallon drum.

One place can get it in 5 or even 1 gallon containers.

It seems like the UPS shipping costs to the supplier add a lot to the cost.

I found it for $260 for 5 gallons. Which means $52 a gallon, has any one found it cheaper else where?

edit -

I looked around more and it seems RC car fuel is NOT the way to go.

Mixing it yourself will be cheaper. The Nitro in RC car fuel works out to around $65-$100 a gallon.

I am thinking about running 20%Nitro 80% Meth
Nitro - $52 a gallon
Meth - $4 a gallon

This works out to $13.6 a gallon for the Mix --- Not too bad.

 

meth head , i know the feeling man

 

buy the concentrated stuff and dilute it down to your requirement

is VP Racing Nitromethane not already very conncentrated?

from the website - " Both products are of the highest purity and consistency and are used by top teams in drag racing around the world. Both mix with methanol for drag, oval track and hobby applications. Both satisfy current NHRA 85% specifications for Top Fuel and Funny Car. "

Unless I am missing something here, this seems to be much cheaper than buying it from a chemical supply store.

 

yeah 7-10% of that stuff will last you a while
