had my car on the dyno the other day, pushed just over 160kw at the treads. problem though, lazy fuel pump, the pressure is good but the flow dropped right down. what is a good replacement fuel pump. should i go internal or rig up an external pump.
mate drop an 044 bosch pump in the tank and solve all your troubles..Paul.....DIRTgarage.

That's impossible

Sorry, but it is...

If the flow is reduced, there isn't enough fuel to hold the pressure. It's that simple

It might be time to have it checked out by someone else. :cheers:

      High temp brake fluid?

      By Komdotkom · Posted

      This has been covered a bazillion times but google wet boiling point vs dry. Motul is only good when it's fresh, once it absorbs moisture it gets pretty average very quickly. So as above, make sure you change it if you're going racing. I run the Endless brake fluid in mind, but only because a mate is a distributor and it's cheap. It's not quite as good as SRF but I'm running 380mm rotors on a Skyline so it's not like they get hot.

      Does 98ron contain ethanol?

      That's the thing, they still add it and it makes fuel cheaper, implying adding 10% of it drops the cost of 91 by what, 5c a liter? I remember when it was barely half the price of 98. Because you know, 85% of what is in the fuel is way cheaper than 91 fuel is by volume.

      Need AC Compressor for R32

      By GTSBoy · Posted

      Auto electricians that do repairs on automotive AC systems can source service kits. I don't know where they actually source them. I do know that there is one available for the R34 comp that I would need it for. If you have to pay someone to dismantle, clean and do needed repairs and fit kit contents, then you'd probably end up spending a good fraction of the cost of a new one. I would not be paying for that, because I would be doing it myself. My mechanic (bro-in-law) will happily source what is needed. Back in the day (like in the 80s and 90s), rebuilding an AC compressor was the standard approach, same as for starter motors, alternators, etc, because new replacements were v. expensive. After the China manufacturing boom and the rise of the disposable approach to everything, people just started throwing broken/worn stuff away and not rebuilding things.

      Is rebuilding it even a thing? Where would the shop find parts for it? I looked at some off these local online stores for my r34 and suprisingly they had brand new aftetmarket ones for $600-800 I think. I guess r32 might be a bit tougher.

      I remember the days when E85 was priced in according to the $ per km outcome. Sure E85 was about 35% cheaper, but you also lost about 35% range... now it's fked..
