Has anyone done an install on the Dorch pump? Would be great to hear what the install was like. I'm sure it's similar to spool install that is already in the thread. Seems like anyone can do this at home in their garage.

Very easy overall install. Everything is pretty much plug and play. It took my friend (mechanic who does most of my work) and I about an hour total. Would have been less but we were kinda goofing off and taking pictures of the install along the way.

I went Dorch Stage 2, because why the heck not. More expensive, but I'm only doing this once. I think it's a great product depending on what power level you are going for.

I'm still using the VTT GC Turbo (that will arrive in Feb-March). I am keeping my Meth.

I'm super pumped to be a part of this with everyone who has been in the mix on these B58 mods (Solid, SC_B58x, Kern etc...)...I feel like we need a national meet-up hahaha
We have plenty of midwest meets/car shows and plenty long, straight highways when you guys are ready to make a trip

I've been talking to a few people on instagram too and we all say the same thing. Plenty of B58 progress on the internet but no one local to do comparisons with. Maybe when more B58s hit the used market? Because around here, people only buy 320i/330i and X-series SUVs. And of course a handful of ///M's.

And before you ditch the pump, see my post above. Just need a pic of both sides of the pump with part numbers to end this debate.

We only have about a dozen or so N5X guys around me and 2 (including myself) B58 guys. I wish we had a BMW group like Colorado N5X.

My car is ultimate sleeper status where I am though. I live 10 minutes from the BMW Plant (Spartanburg, SC) and most of the people at the plants get extremely good lease deals, so i'd say half or more of the people working there have BMW's. I kept my car looking almost stock because of this so most people that race me think it's just a stock lease car, but little do they know.

My Supra pump is on backorder still and hope to have it and the custom tune done by the middle of January. I live in Sioux Falls, where in the Midwest are you?

Same. This year we had a good group with a stage 2 435 and a M4 Comp going to a few meets and doing cruises. I also "met" another N54 guy but still have to find time for us to actually cruise together. We'll see.

same pump I'm willing to bet the "back order" is simply because BMW orders 500k per year while Toyota maybe gets allocated 20k. But the Bosch part numbers are the same, and the Toyota part has a BMW part number to boot.

I'm all the way in Cincinnati though. Maybe Chicago is more central than I thought haha. But we have a lot of Euro shows in Ohio, Kentucky, and Indiana. And a few of the half mile events make a stop in the area.

Looks like a pretty simple install.

Did you reuse the gasket?
Did you make sure the cam lobe was in the bottom position?

My TU pump came in I'll make a video of the install, but don't anticipate running any logs until temps warm up. Roads have snow and I'm still on summer tires, but once we get above 40F I'll do some logs. Looks like next week should get up to 50 or so. Going to run Stage 1 now until I get my tank down low, fill up with E, and flash my F80Paul base map to get things rolling.

I also have a set of digital calipers, so I can take some measurements between the HDP5 and HDP6 pumps. Any requests? Mine didn't come with the cam follower, but I can compare piston length, diameter, etc.

If will change to supra HPFP will increase the power in OTS stage2 map? or need custom map for for increasing the power on this pump?

You'll need a custom map. If you see any dips in rail pressure when running the E30 maps, the upgraded pump will help eliminate them.

Just fact checking on the flow data quoted by Dorch Engineering on their web site and in the first post here regarding stock Bosch pump for original B58 and B58TU.

From the Bosch web site and data sheet here https://www.bosch-mobility-solutions...pressure-pump/

Bosch HDP5 (OEM N55 HPFP) has a maximum flow of 1.12 cm3 per cam rotation

Bosch HDP5 EVO (Rev C) has a maximum flow of 1.2 cm3 per cam rotation, if using a 4 cam x 4.7mm lobe. BMW uses a 3 x 4.7mm lobe so the maximum flow with the BMW cam specs is 0.897 cc/rev (188 l/hr at 7000 rpm) This product has a 250 bar or 500 bar internal pressure relief valve, reduced internal restrictions and introduction of EVO parts (outlet valve) For original B58 the 250 bar internal pressure relief valve is used.

Bosch HDP6 (has a maximum flow rate of 1.3 cm3 per cam rotation (210 l/hr) and 500 bar internal pressure relief valve. With the 3 x 4.7mm lobe the maximum flow rate is 1.1074 cc/rev (232 l/hr at 7000 rpm)

So, the HDP6 with the stock B58 cam profile provides about 23% more flow than the stock HDP 5 EVO (previously calculated 8.3% based on the maximum Bosch flow rates using the 4 x 4.7 cam profile for both pumps)

Based on the same 3 x 4.7mm cam lobe profile XDI-35 (10.5 mm piston) has capacity of 1.221 cc/rev for 256 l/hr (36% more flow) and XDI-60 (11.5mm piston) is 1.465 cc/rev for 307 l/hr (63% more flow) at 7000 rpm

Edit 2: based on info from Dorch that the cam lobe is actually 3 lobes x 5mm lift for B58, revised calcs:

HDP 5 EVO (stock B58) 0.954 cc/rev = 200 l/hr at 7000 rpm
HDP 6 (B58 TU) 1.178 cc/rev = 247 l/hr (23.5% increase)
Dorch Stage 1 1.299 cc/rev = 272 l/hr (36% increase)
XDI-35 1.299 cc/rev = 272 l/hr (36% increase)
Dorch Stage 2 1.558 cc/rev = 327 l/hr (63.5% increase)
XDI-60 1.558 cc/rev = 327 l/hr (63.5% increase)

So, the HDP6 and Dorch Stage 1 provides about 8.3% more flow than the stock B58 HPFP

Anyone actually have actual specs, i.e. cm3 per cam rotation, for the XDI and Spool pumps?
if TU pump have just 8%more than 1-st gen B58 pump, why it can handle 600whp cars but stock pump can't more than 450whp???

450hp with stock turbo, 600hp is non stock turbo. remember that with the same fueling/boost bigger turbo will give more hp

Coming soon. I'm home with a 2 week old girl and a 2 year old boy that isn't used to not getting all the attention yet, so it's taking a bit but i'm almost done with the install. Working between naps + trying to make the video is just making it take longer than it typically would for someone that can focus on the swap. I also want to run logs before posting the video to make sure it's performing how it should. But as of now she's mounted and ready to test.

That's probably right. Just everyone needs to keep in mind that we can only use our cam sizing. The piston on the TU pump is longer and I'd guess that the lobe on the TU engine's cam is larger as well, so we may not be getting the full potential capacity of the pump without swapping cams. But still seems like a viable upgrade.

Not true. If you are fuel limited then a bigger turbo won't make more power.

of course it will. bigger turbo will have better flow and will need less wgdc, bigger turbo always makes more power with same boost vs small turbo. check VTT post where they just changed turbo and gained 48whp with exactly the same tune. Engine is pump. flow is important.

From the Bosch web site and data sheet here https://www.bosch-mobility-solutions...pressure-pump/

Bosch HDP5 (OEM N55 HPFP) has a maximum flow of 1.12 cm3 per cam rotation

Bosch HDP5 EVO (Rev C) has a maximum flow of 1.2 cm3 per cam rotation, if using a 4 cam x 4.7mm lobe. BMW uses a 3 x 4.7mm lobe so the maximum flow with the BMW cam specs is 0.897 cc/rev (188 l/hr at 7000 rpm) This product has a 250 bar or 500 bar internal pressure relief valve, reduced internal restrictions and introduction of EVO parts (outlet valve) For original B58 the 250 bar internal pressure relief valve is used.

Bosch HDP6 (has a maximum flow rate of 1.3 cm3 per cam rotation (210 l/hr) and 500 bar internal pressure relief valve. With the 3 x 4.7mm lobe the maximum flow rate is 1.1074 cc/rev (232 l/hr at 7000 rpm)

So, the HDP6 with the stock B58 cam profile provides about 23% more flow than the stock HDP 5 EVO (previously calculated 8.3% based on the maximum Bosch flow rates using the 4 x 4.7 cam profile for both pumps)

Based on the same 3 x 4.7mm cam lobe profile XDI-35 (10.5 mm piston) has capacity of 1.221 cc/rev for 256 l/hr (36% more flow) and XDI-60 (11.5mm piston) is 1.465 cc/rev for 307 l/hr (63% more flow) at 7000 rpm

So based on the above and all other things being equal (turbo, tune, bolt-on's), is the XDI the best future proofing option? These things scale based on need, correct? Ie. if the car is stock, the pump will perform at stock flow (as needed), and increase as the demand requires up to its above-mentioned limits (1.221 cc/rev)?
