How does the Evolve CSL intake compare to the Eventuri they also produce in figures & costs?

Sadly not, since the "before" stage was a broken engine. The whole bottom end has been rebuilt, head skimmed, new cams etc.

As mentioned above, the last time I was at Evolve I got quite low numbers, with their tune and the Evolve airbox. Will see if they still have it on file as I can't remember what it was but pretty sure it was mid-330s...

Completely different. The Eventuri is a Gruppe-M style cone intake with carbon shroud/heatshield, that still uses the MAF etc. "CSL" airbox does away with the MAF entirely, and runs an Alpha-N tune. Much larger air inlet.

Also, think with tune and airbox the CSL style is usually in the £2k-2.5k range. Eventuri not sure - but guessing about £400 (not every looked)?

Really happy this car is back on the road. One of the best.

True but its not dependent on getting the power down on rollers via the wheels

Still the point here is that your engine is clearly in a healthy state whatver the exact output

Sixspeed happy to see your car back on the road and stronger

Can I ask you if you see any differences after the tuning on the following situations:
1) At cold start the car starts the same way as before the tune?
2) What is your idle rpms?
3) Have you noticed a difference on the mile per gallon consumption?
4) Have you seen a difference between driving the car on with sports mode on or off?
5) Do you have a smell of gasoline out the pipes?

With the cams do you see any difference in the low rpms?

Thank you...

WOW! impressive numbers... sure you must be enjoying this amazing machine!

Very nicely indeed 6speed. Congrats again on getting it sorted mate. Sure as heck are very healthy those numbers.

Spot on! Did GS say anything about running in the bearings and cams/followers?

that must fly!

Really happy with the result, 378bhp and 290lb/ft

Spec is H&S exhaust (cat back)
Evolve "CSL" intake
Schrick 288/280 cams

Back at the 'Ring next weekend. Hopefully manage more than 2 laps this time!

Glad you got it all sorted and showing some good figures, but you know the only real way to test it is against my car on a airfield runway right.

Haha!

I'm there on the 6th? (although in my newly acquired Giulia QF, not the Z - but it could be there... )

Ha wouldn't really stand a chance against the Guilia, saying that will an Alfa make it to the end of the runway!!

I'll probably be at the goodwood breakfast, so will keep an eye out for you.

That's a very healthy figure! Yours, TomK's and Vanne's are my ideal engine spec Z4Ms

Wow.. Something good came out of it, very nice!

Hey FD3S, long time...

1. Cold starts are a pretty spluttery, lumpy affair, but it smooths out after a minute or so.

2. 1,000rpm

3. MPG on a cruise seems much the same to me. I'm sure in-town/city driving would suffer a bit just due to the increased idle RPM.

4. Ive never used sports mode on my Z, and haven't tried it since the new tune, but i'l try and let you know.

5. Not that I've noticed!

6. Low RPM is still very driveable. It's probably a little less torquey than before but hard to discern, and I don't drive the car as often as I used to. Either way it doesn't feel a whole lot different at low RPM to before, so far!

Brilliant results!

Have they sorted the heel and toe issue with their software now?
