What camshaft 310R?

Anybody know what camshaft is used for the 310R?  Anybody measured the lobe lift?

virtually no public domain knowledge on the sigma engine tuning compared to the K-series.

I measured the lift on the 125 BHP TiVCT when I changed the belts a while ago and it was 8.9mm IN and EX.  Camshaft was marked Ford 300610E

my guess is that Caterham use piper cams for the upgrade to 152BHP, but it is noted 'not suitable for EU spec', which I think means not homologated, so I might go my own way when time allows

Have a word with Sevens and classics, they converted mine, better value than CC.

Hi Dr Evil,

Cam profile is a Piper / Caterham profile.  Not available to buy direct from Piper, only Caterham.  Think others might be using a Kent Cams profile that is similar but does that make a non Caterham 310....still a 310?? 

Let the masses decide.

On another note, we're about to launch our throttle body upgrade for the 310 following rolling road testing this Monday.  Results are 174bhp and 135Lbsft of torque.  Should make for a great upgrade and one we can see as being very popular.

Regards

SKC

Many thanks for the info.  Heard nothing but great stuff from premier power, but I'm looking for a DIY option; part of the fun!

Searching online, looks like Newman cams might have a TiVCT option as well.

Hi Dr Evil,

The issue you're going to have is calibration. If you don't run the Piper cams that Caterham use, there is a good chance the calibration won't work.  If you then want an open ECU for a Ti-VCT Sigma, a replacement MBE ECU is about £1300.00 + vat and then there's the time on a rolling road to calibrate it with someone who knows what they are doing.

Fair point - may not realistic DIY.  I put MGTF135 cams in an elise together w/verniers and the MEMS ECU accommodates the mild increase of flow with grace, though to be fair I'm rarely in WOT.

My challenge is that is that my Caterham is an EU export model so has a Ford Focus/Siemens ECU with a drive-by-wire throttle body, so without changing all of that for a measly 20-30bhp at 7000rpm, I'd be thinking of adjusting the stock ECU base maps by running closed-loop and looking at the short-term fuel trims for clues.  Was thinking to try an experiment first with a freer-flowing MAF/air filter housing as the stock airbox looks to be a mondeo unit fed through a restricter pipe from the heater box but that's another story.  If that works, I might try for cams.

Is user SKC Premier Power?

For this upgrade, if you already have a full 310r are you saying that with just the throttle body change it will go up to 174bhp? Does it then need mapping or anything?

What is the cost please?

Hi SKC

Is this only for the Ti-VCT or could it be used on a earlier Sigma engine ?

Thanks
