ESS TS Pulley Upgrades

Hi

I have searched the forum for info on what sized pulleys people are using on their ESS twin screws, the information seems to be very spread out and random. I was wondering what sizes people were running with the standard ESS ts2 and ts2+ tunes, as well as with standalone ecu's. I am running the standard 81mm TS2+ pulley and tune, and was wondering what others have done to get a bit more out of the setup.

Thanks

Dave


For ease of use, below is a summary of pulley sizes/ boost, as advertised (I will update as new info is shared):

Stock compression- 30 lb injectors
90mm diameter: 7 psi ESS Standard TS1
85mm diameter: 8 psi ESS Standard TS2
83mm diameter: 8 psi ESS Standard TS2
83mm diameter: 8 psi ESS Standard TS2+
81mm diameter: 8.5 psi ESS Standard TS2+
79mm diameter: (to be confirmed, not supplied by ESS)
78mm diameterto be confirmed, not supplied by ESS)
77mm diameter: 9.5 psi, not supplied by ESS

Lowered compression- 42 lb injectors
70mm diameter:14 psi on newer kits
68mm diameter: 15 psi on newer kits
68mm diameter: 14 psi ESS Standard TS3
63mm diameter: 15.2psi ESS TS3 Upgrade
60mm diameter: 16 psi ESS TS3 Upgrade

Thanks for the reply, stock ess tune?

Thanks cosmos328ci, that's with stock compression, 60 thou MLS head gasket, raceware head studs, and a haltech stand alone ecu if I'm not mistaken?

Close, but, the engine is stock (never been apart) except for the Haltech ECU.
Currently getting my final tune for E85 and Meth/Water injection, should be completed by the end of next week. (hopefully)

Really looking forward to seeing your figures with the e85

I spoke to my tuner today and told him to pull out the stops on my tune.
He asked how aggressive do I won't the timing, I said when it knocks, knock off 1 deg of timing. LOL

Oh my.


My first thought is that there's No Room For Error.

Meaning, that something as simple as a fill-up using "Bad" gas could mean a motor rebuild. Something to consider.

Something to keep in mind also, that knocking != peak power.... you may be 3-5+ degrees past peak power when it starts knocking...

Near the bottom of the page to the above link, Asbjorn from ess suggests it is possible, but would void warranty, to run a 9.5psi pulley with the TS2+ and 95 octane fuel.

Wondering if this may be a safe option for myself as I only ever run 98 octane.

If I'm not mistaken, your 98 octane is about the same as my 93 octane. I would definitely look into this.

We have 98 Ron, which is the same as 94 aki according to Wikipedia.

Hi, firstly sorry for thread jacking.


If 93 in the USofA is 98 in Aust, when Asbjorn recommends 94-95...... would that not be higher than 98 in Aust?

This is my Dyno using 98 @ 15.5 psi on a stock M54B30 engine.

DynoDynamics. This would be about 365 whp on a Dynojet.

All good cosmos328Ci, I'm all in for as much info as possible. I don't know if you have dealt much with rob43 but he is a great guy who is very helpfull. I thought his question was a little odd with octane ratings, but once you do a search, it seems every country has different numbers and systems for octane readings, some are quite deceptive to octane.

TS1 is 90mm ~7PSI
TS2 is 83mm (older kits have 85mm) ~8PSI
TS2+ is 81mm ~8.5PSI
TS3 is 68mm and 14PSI, 63mm with 15.2PSI

Found an old post of Asbjorn, will adjust the mistakes I have made in original post.

Will also share a bit of research I have been doing on camshaft overlap. I read a lot, probably too much, but ESS tunes for these TS systems are either based around oem cams, oem ZHP cams, or the 248/256 FI cams. I have noticed a few members are getting great power figures with other cams, but these require custom tunes, or being used with standalone ecu's. The list below is the installed overlap of a few of the more common Schrick camshafts, calculated from the Schrick camshaft catalogue.

248/256=41 crankshaft degrees
248/248=41 crankshaft degrees
264/248=43 crankshaft degrees
272/256=47 crankshaft degrees

I can't find the appropriate data for oem cams to calculate installed overlap. I am not sure which cams are approved for use by ESS, but I would suggest that the overlap would be far too great with the 272/256 and standard ESS tunes. I have read a few posts where people are using the 272/256 cams with stand alones or custom tunes with smaller pulleys (to compensate for loss during overlap) and making great results power wise.

Im more so adding this info as I see a lot of posts of people going as far as they can NA, and then switching to FI. I am aware of a member with the 272/256 cams installed, who was told prior to TS install that they would work with the ts2+ tune, but that doesn't seem to be the case

Would be nice if anyone could add to this also
