Sard Fuel Pressure Regulator E85 Safe?

[Chris32R]

Hey guys,

Just wondering if anyone can tell me if the Sard FPR is safe to use with E85?

Did a search but couldn't find anything.

Cheers

Can't give a definite answer but plenty of people using the stock or nismo ones without problems so should be fine

[scotty nm35]

Just make sure it is a genuine one, there are a LOT of fake ones getting about.

Or just buy an SX reg like I did. it's been working fine for over 4 years.

I'm using a Sard FPR with E85, have only been using E85 for less than 6 months but so far so good.

[Gareth87]

Just had it pointed out to me that my sard reg probably isn't E85 safe. Anyone had one fail? I can only assume that if a lot of you are using a stock RB reg, that an aftermarket one would have a good chance of withstanding problems from E85..

Why not use a home grown product like turbosmart, I'm all about the jap stuff but it's pretty hard to ignore the quality of some of the turbosmart stuff.

[Chris32R]

I ended up putting mine in, I've been running E85 for nearly a year now (about 3000kms), no problems to report so far

[Gareth87]

• Gts30t - I like turbosmart stuff, but I don't want to spend money on a new reg if I don't have to..

Chris 32R - Do you mean you have put your sard reg in? or stock?

[Chris32R]

I put the Sard FPR in. I was a bit worried about it at the time hence why i started this thread. Tbh, I wouldn't worry about it too much, It'll be fine.

Like I said, I've had it running straight E85 for a year, no problem.

[Gareth87]

Thanks for the info Chris, with any luck mine will be the same.

3000km in a year. I did 3000 km in 2 weeks in my GTR over summer. Sorry off topic.

[GTR_JOEY]

Had mine for 12months.. Over 10k in kms

Running both 98 and ethenol, no problems

Has been sitting with ethenol in it for quite some time now.. If its stuffed when I start it next month I'll know why

[Chris32R]

Haha yeah I definitely spend more time working on it than I do driving it.
Hopefully i'll leave the spanners in the shed a bit more this year so that I can take it out more on the weekends

On another note will the standard SARD restrict me to get 400kws+ what sort of power levels are people running their SARDs at?

[scotty nm35]

Regs don't flow 'Power', they bypass fuel to hold a certain pressure.

If you can run your desired base fuel pressure with the injectors off and pump running, then the reg has enough flow. Stick a larger pump in, and it might not be large enough...

Sorry don't understand that answer. Bought a Tomei Type L hopefully it's sufficient but still interested in a simpler version of you answer if possible

If your fuel pressure spikes too high you need a larger regulator, it is not dependent on the power your making.

Kind of like the size of a wastegate on a turbo. The more boost your running the smaller the wastegate can be as it is bypassing less air from the turbo to maintain that boost pressure.
