How To: Identify 2.7RS MFI pump

[obrut]

Morning kids,

I'm looking at a MFI set up for the new race motor (this thing is eating $$$'s like you wouldn't believe - 7R case, 10.5:1 pistons, twin plug heads....)

How do I tell if the MFI pump is 2.7RS or 2.4E? - can you tell from the serial no. on the pump?? (It is very close to the no. on the pump of a real RS I have compared it to that I know has its original pump)

Is there something you can measure - stroke of the cam??

The rest of the setup appears to be ridgy-didge 2.7RS - 36 to 38mm throttle bodies etc

Any help greatlly appreciated

Cheers - Ryan

The first seven numbers are always 0408 126 followed by three more numbers which give you the type of pump as follows

69' E 002
69' E 006
69' S 001
69' S 005
70/71' E 010
70/71' S 009
72/73' T 015
72/73' E 014
72/73' S 013
72/73' S 021

These are the Bosch numbers that are written on the pump. I don't have the number for the RS pump. I got these out of the check,measure adjust manual.

Thanks for that, the no. on the pump is 0408 126 015 (ie. 72/73 T)

How do you check if the space cam is 2.7RS or not??

The number on an RS pump is 0408 126 019. Not sure about the the space cam, I have never seen mine apart.

This guy could probably tell you if there was a way to ID the cam without taking the pump apart:

Pacific Fuel Injection (Gus Pfister)
Suite B, 153 Utah Av
South San Francisco, CA
Tel. 650-588 8880

I think you should probably assume you have a T cam in your T pump. The RS cam is available if you decide to rebuild your pump to RS specs. I think the S and RS pumps have the same specs but maybe Warren Hall or someone else can clear this up...

other stuff on the pump???

PED 6KL60/120 R3Y 0408 126 015

I believe Otto (http://www.ottosvenice.com/) has a real RS pump available for sale and I bet he would "deal" on it.
