135 Mgtf Cams Fitted To My Std S1

[KurtB]

Sounds like a good mod Jody, good work! I will be selling my Exige exhaust inc manifold if you feel the urge, just let me know. (available from mid Nov)

 

Cheers,

Kurt

Bill, indeed you would need this on an S1. However on an S2 they should drop straight in?

I don't know if the camshaft sensor pads would work in inlet.

Been talking to (pestering) Jody a lot about this mod, and I've purchased a 135 head + cams, another set of cams, a digital vernier to measure lift, and a alloy inlet/52mm throttle body (So far I'm in the hole £150, but need gaskets, locking tool and seals.)

 

 

I'll be doing a little how to if anyone's interested, covering how to ensure the cams are fine, they're correct, and how to fit, with some pics. Then a Dyno run to see if it makes a bit more powersssss

 

Granted, I'll be doing the same mod on a S2, I've bought another set for a mate who hopefully will fit them to his S1, and can grab a few pictures of fitting the ignition stuff to his too.

 

The only difference between a 135TF and the 120TF is the cams, throttle body and inlet. Wanted to check if the inlet side is slightly ported to match inlet but it isn't! 

IIRC standard cams have 9mm lift and 135 cams have 9.3mm lift. To measure the lift, take a set of verniers. Measure across the round part ( at 180 degrees from the pointy bit ) It should read around 30mm. Then measure the pointy bit from the back of the round bit. This should be around 39mm or so. Take one from the other for the lift.

 

I also have a feeling 2 x VVC exhaust cams used in a standard head will give good gains?

 

These guys make 9.5mm, not 9.3mm

 

This website has some good info too!

Ok so having the cams in now for a little while tonight myself and Marcus decided to get the cars on the Dyno, (We have just put Marcus a set of 135 cams in too) so here are the results (red line is my std cams from a 2013 run and green line the new run:

 

 

So all in all its a great little mod for the money ????

[un1eash]

Very good gains for the money.

 

You should of said you were going dynodaze and I would of popped along. Been meaning to see how the Elise is running, it hasn't moved since its service in October.

[Martin R]

17 BHP and 5 lb/ft of torque are good gains for the money    

[Alex B]

Good results Jody.

Brilliant for the money.

This!

 

Well done Jode :-)

Excellent result Jody.....

 

I often question myself why I ever went sown the slippery slope of big power ?

Agreed.

You cant escape the fact a 170 bhp or lower K is a cracking motor. Built right it will last for 100K and dozens of trackdays with a following wind

My standard 120 bhp motor has done nearly 96k miles now. Touch wood, it feels as strong and sweet as ever.

Get some 135 cams in Dean, you will not be disappointed!
