has anyone here put cams on their ea82 spfi before?? if so, i would like to know the results.

Not an an SPFI, but an n/a ea82 (Weber carb). I still don't have it tuned up for maximum performance yet, but it has definitely helped substantially. I would highly recommend doing this. The only drawbacks I've found are a slight decrease in fuel economy, and a bit rougher idle (Both might be alleviated once I modify the disty for more timing advance).

Fuel mixture adjustments will also eliminate the rough idle along with the timing adjustments.

I did. I had no muffler with the stock system, and a cone filter on the MAF....dont expect too much excitement until about 5500 RPM....on the SPFI EA82, it opens up the top end...doesnt do much for the low eng and mid range thats really noticeable....at least on the 3AT i had.

 

On an EA82T, it makes all the difference in the world. I would try to go with the bigger profile cam in the EA82 SPFI.

Just got off the phone with Delta Cams. Dude said they can do high end or low end performance cams for EA82 NA. I spose it depends on what you want. Personaly I want low end for offroading. He told me UP TO 10% gains from the low end performance cam. I would assume this was after tuning for the new cams.

 

Callem up!

I think thats before tuning.....i know that on the EA82T, theres really no tuning needed, but After i tuned mine in with timing adjustments....where it was just DA BOMB before....after playing with the timing it was DA NUCLEAR!!

Those are some big words! I have been seeing other here say the same. Does anyone have any before and after cam installation dyno numbers? I'm interested in seeing just how big a difference the cams make. I've seen your dyno sheets WJM but I may have missed others that showed a before and after scenario. You now of any links or what not to someone with this info?

We ahve TWO results of before delta cams....the RX i have now and my wagon on 9.5:1. Pleiades is planning on putting his RX with Delta cams on the dyno some time...and I will get the bigger cams and do I dyno run when i get some other things done.

 

My wagon put down 99.2 at the wheel, and the RX put down 88 or so.
