Just FYI the 4 aluminum spacers are for the fuel rails. I didn't see that in the install guide and I read it at least 20 times.

you are correct, these were designed so the new injectors are properly spaced and can be clipped in properly. will need to add this to directions.

I'm assuming you mean the angle bracket spacers?

On page 17 they have a picture of them installed lifting(holding the SC up) but you're correct, nothing around to specify when to install it hardware to use. IF this is what you're talking about.

I'm also assuming the long bolts in the pack are for these four installs?

Actually, I take that back, these are installed earlier on page 9, I got ahead of myself.

Regardless, is this still what you are referring to here?

Yep, those aluminium templates are purely for aligning the four SC mounting blocks (spacers) that as you mentioned serve to "hold up the SC" at the correct height in each corner. Harrop probably include the alignment template(s) to avoid backwards installation of the four mounting blocks. The Harrop SC installation manual is good, but it is "open to interpretation" in some areas. Originally, back in 2015 the install manual wasn't even available for study until "after" purchase. I know, because I asked for a copy so I could see how difficult or simple the install would be. That's a story for another day.

Needless to say the shop who did my install ran into problems with some of the DME wiring and that shop is now no longer in business... Read the manual at least two or three times prior to attempting an install at home, and call Mike if needed since he is highly knowledgeable on the install details -> and all of the nuances that go with debugging any gremlins. In my case, my kit had a bad bypass valve actuator which Harrop expressed shipped to me from AU! DukeofAlexandria Good luck with your install. Can't wait to hear your review.

Hey DOC!

Yes, correct, the long aluminum flat template (not shown) was also included and I have all that, so this helps answer my question and I'm good to go.

When nycplumber mentioned 'spacers', in my mind I thought more along the lines of large stainless/aluminum washer for some reason and went looking through the hardware kit and was a bit confused ha. After reading the online guide, it was on Page 9 and does seem to cover that area, so all good!

I've gone through most of it and it seems relatively straight forward. I've built bare block engines, installed countless parts, and installed centrifugal S/C on other car's before, so I have a decent amount of knowledge above the average user. Even with advanced knowledge I'm no certified mechanic, but this doesn't seem TOO far out of scope for a person who doesn't know much and wants to tackle a project and has the time.

I'm going to take extra time to get this buttoned up because I also have the do88 big pack kit I have to install. I ALSO might have went on a shopping spree at FCP last night and I MIGHT have ordered a bunch of sensors and replacement items to reduce any heartache; water pump, thermostat, alternator, valve cover gaskets... - this is exactly what I told you I feared, running down a rabit hole haha!

Will send updates as they come, thanks!

Just to be clear, I do NOT have these anywhere in my kit. Not in the hardware kit, on the SC itself, or in any of the boxes/bubble wrapped items.

Are you SURE you had to use these? After some mock up last night, I believe the picture of the angle aluminum brackets I posted are what should be used?

Let me know, thanks!

OH WAIT WAIT WAIT. Is this for the NEW kits? I have a kit that has been sitting since the 'first last batch' (when Mike announced no more sales in US) of Harrops were sent out, back early last year.

I think this might be for some of the 'newer' kits within the last 3-6 months. Mine is coming up on a year so I think these don't apply to me.

Let me know what you think, thanks!

Thanks for bringing this topic up in this thread. I'm not familiar with these washer / spacer parts. Inside each bid red box shipped from Harrop is a parts list - sort of a blue print packing checklist. What is the description given for these washers? I posted the printed parts list that came with mine earlier in this thread from the 2015 vintage. Perhaps improvements were made? Can you post a photo for the benefit of others showing where these washers are installed? Thanks for your help and contributions.

Going to tag on with Doc here and say I've reviewed my pick list/parts list and do not see these washers described anywhere.

nycplumber Do you know what part number on your pick list these were and what was your build date for your kit?

Mine was 06/2021, if I remember correctly you purchased a new kit within the last few months, right?

I curious as to what others are seeing from IAT differences vs ambient temp?

As an example, when driving at ambient temps of 20C (68F), my IAT hits about 35C(95C). And it goes up from there if I drive harder.

I'm always at least 15C (do not convert to F) above ambient, even on long highway cruises.

Am I in the ball park of what others are seeing?

I believe it's the last item DukeofAlexandria. My "picked date" 30/11/21

OK, I do not have that part on my pick list. Additionally, the more I look around and find pictures or read through the thread, the more I believe this is simply because of the injector change in the later batch of kits.

This makes sense because those injectors (if I remember from someone else talking about it) are SLIGHTLY taller, which would require this washer to raise the fuel rail slightly.

I believe I'm fine and should be ok, thanks so much for posting that and unless someone tells me different or I find that installing the fuel rail back on is just absurd, I believe I'm good to go!

Thanks again gents!

-Duke

[nycplumber]

Yes they are just spacers for the different injectors. I would post a pic unfortunately though it's really hard to get a good one. But it's hard to confuse where they go when you understand their purpose. So to clarify you put them directly onto the throttle body and the fuel rail mount sits on top of that. Then the supercharger bracket sits on top of the fuel rail. 4 fuel rail m6 bolts supplied by harrop match up with the 4 spacers and 4 fuel rail mounts. If you don't install this spacer on the new style injectors you will start to put load on the injectors and not just on the throttle bodies.

For clarification, This is for kits that come with the black injectors only. The blue ones do not require these. It is possible to install the black injectors without these spacers although it's a better fit with them installed.

Still looking for my E90 to build but very impressed with this kit. By any chance is anyone selling 😅 As soon as I lock one down I’ll lock a preorder on a kit. Hoping to have this car ready by November for a half mile.

Selling their E90 or their Harrop kit? There's a used Harrop kit currently for sale here:

Both I guess. If I had an e90 I'd hop all over that kit, even if I need a few things it seems worth it. Just can be difficult to find an e90 at the moment.
