I have now received all the pumps and am now awaiting payment. If i do not receive your payment by wednesday i will have to send your pump back to bosch. On that note i have at this point 1x040 and 2x910 spare so any one interested give me a yell

hey guys,

have any of u who bought the bosch 910 pumps installed them yet?

I needed to know if they are loud?

Also, are the bosch 975 pumps much better?

(I'm aiming for 190 - 200rwkws and was told to get a bosch 975 pump, but it only flows a little bit more than a 910 but is a lot more expensive, why is this?)

sorry to hijack but any info is much appreciated.

Thanks heaps!!

A 910 will support up to 335 rwkw which will be ample for you

I'd like to know how you worked that out ?

BHP is the HP measured at the flywheel. Now using my formula below this is what I'd rate those Bosch fuel pumps.

Formula = BHP x 0.746 (hp -> kw) x 0.8 (using a 20% drivetrain loss which is quite conservative) = rwkw

So that means:

910 rated at 450 bhp = 335kw = ~269rwkw

040 rated at 520 bhp = 388kw = ~310rwkw

044 rated at 730 bhp = 545kw = ~435rwkw

I'm personally using the 040 pump.

Sorry calculation error on my behalf didnt allow for the 20% drive train loss. The bhp is still correct so people could have worked it out from there.

Give me a break im doing a favour getting these pumps cheap for you sau guys making no profit for my self.

Was there an 040 left? If so I'll take it but Im outta town til after Xmas.

nah sorry, there are only some 044's and 910's left but I will be sending them back to bosch if they're not purchased by Wednesday (tomorrow).

    • Yeah, it's getting like that, my daughter is coming over on Thursday to help me remove the bonnet so I can install the Carbuilders underbonnet stuff,  I might get her to give me a hand and remove the hardtop, maybe, because on really hot days the detachable hardtop helps the aircon keep the interior cool, the heat just punches straight through to rag top I also don't have enough hair for the "wind in the hair" experience, so there is that....LOL
    • Could be falling edge/rising edge is set wrong. Are you getting sync errors?
    • On BMWs what I do because I'm more confident that I can't instantly crush the pinch welds and do thousands of USD in chassis damage is use a set of rubber jacking pads designed to protect the chassis/plastic adapter and raise a corner of the car, place the aforementioned 2x12 inch wooden planks under a tire, drop the car, then this normally gives me enough clearance to get to the front central jack point. If you don't need it to be a ramp it only needs to be 1-1.5 feet long. On my R33 I do not trust the pinch welds to tolerate any of this so I drive up on the ramps. Before then when I had to get a new floor jack that no longer cleared the front lip I removed it to get enough clearance to put the jack under it. Once you're on the ramps once you simply never let the car down to the ground. It lives on the ramps or on jack stands.
    • Nah. You need 2x taps for anything that you cannot pass the tap all the way through. And even then, there's a point in response to the above which I will come back to. The 2x taps are 1x tapered for starting, and 1x plug tap for working to the bottom of blind holes. That block's port is effectively a blind hole from the perspective of the tap. The tapered tap/tapered thread response. You don't ever leave a female hole tapered. They are supposed to be parallel, hence the wide section of a tapered tap being parallel, the existince of plug taps, etc. The male is tapered so that it will eventually get too fat for the female thread, and yes, there is some risk if the tapped length of the female hole doesn't offer enough threads, that it will not lock up very nicely. But you can always buzz off the extra length on the male thread, and the tape is very good at adding bulk to the joint.
    • Nice....looking forward to that update
