Has anyone actually found the cc/stroke for the stock HPFP? What about using the HPFP from other applications to raise the cc/stroke for budget-minded individuals? lastly, what is the longevity of the Xtreme DI HPFP-35?

TIA Daniel

Yeah man I found it odd that when I bought these injectors from whoosh there was pound per hour or cc rating on the injector. Only stated on the website is 93% more efficient. So whatever I bought them. I went online once receiving the injectors to find out what cc they are or whatever they’re glow rate is. And come to found out they are OEM jaguar injectors. All the numbers match perfectly. SKU, part number, all the etchings on the injector itself match. Just a little odd to me dint ya say?
do you remember the part number by any chance

So, the ones I purchased from whoosh are the Uprated with the white seal. The puma speed injectors are the double sealed high flow. Not sure of the difference. However these injectors are absolutely the same as the oem jaguar injectors. I received the injectors I bought factory packaged in Bosch boxes. So unless Bosch is machining these themselves I’m not sure how they are getting machined and they factory packaged back up. I’m just really looking to debunk this and maybe make upgrades injectors for this community more affordable and possibly get something more exact for our cars. Like I also have b series civic that has Injector Dynamics 800cc injectors in it. I’m curious as to why these injectors have no flow rating? Maybe because they are just oem. Idk guys
part number?

Here is a picture of the Bosch injectors I got recently. Maybe others will be willing to post pictures of their own and it can help the community. 🙂
All injectors and packaging and part numbers are identical and the nozzle has 6 holes.

I'm curious about the measurement from tip to the 'left' side (bottom) of the seals that Puma shows here.

Thank you! I have a huge favor. When you pull the stock injector will you please post side by side pics and take measurements to see if they’re the same length. For science!!! Thanks again

I believe Tune+ installed the uprated injectors without the double seal with no issues. I remember asking Adam about it and he basically told me it wasn't necessary, however it was one of the things that stopped me from buying them when I had the FiST.

Ok! So finally had some time to get the injectors and Xtreme-DI hpfp installed. The most difficult part was removing the OEM fuel rail without damaging anything. Just to be safe/prepared I also ordered a new upper and lower injector seal kit from rockauto. I actually didn't need most of the kit since the new injectors came with almost everything needed already on. Two things I did need to add to the injectors was a clip that goes on the top of the injectors and a "seal/seat" that goes on the bottom. The latter I had to reuse from the old injectors because it didn't come with the kit. 😩 I was annoyed I had this "complete" kit and only used one piece and it didn't even have the other.

Here are some pictures and a few measurements. I hope y'all appreciate that I had to go and buy a micrometer just for this. 😂

Old injectors. I measured them from the top of the injector to the tip of the nozzle.

New injectors. Measured in the same manner.

Here is a picture of how the injectors look with and without the seal/seats.

Quick tip nobody tells you about installing the new XDI HpFp is you remove the low pressure hard fuel line from the hose then clip the hose directly to the new pump.

You will need to gently bend the fuel line that goes from the new pump to the rail.

I didn't use any special tools to install or remove the fuel injectors or pump and the car is running great.
