Finally had my belts done with group n timing and mapped by EFI.
Red graph was from power run pre work in March

Thank you to @NorthloopCup for advice, making the timing tools and matching my inlets.
A thank you to Steve and Andy at Birchdown who have absolutely worked their socks off on my car.

Massive torque increase right in the middle, how does it feel on the road?

If I can replicate that graph I’ll be happy!!! I’ve got pretty much the same mods as you

Oh forgot 197 injectors. Chris advised me to get some when I did the power run

Chances are you wont, ITBs with little runners means you're sacrificing torque to have the power up top.

The way it picks up from 70 in 5th - it’s like a different car. Unfortunately the knock sensor spat it’s dummy out on the last pull so it’s killing power above 5k. Luckily Chris had finished an was just doing a final pull. Getting one on Wednesday so hopefully it will cure it

Hello, can anybody tell me if 182 with grup N timing EFI remap , 182 exhaust and cat will pass MOT?

 

[hipwell]

I was told by somebody once that itl struggle on the emissions due to overlap

 

[497adam]

Will have to see if mine will has I’ve got a sports cat

I've got the car in the original post (ish, i reshelled it due to rust but that's another story).
Currently in the process of doing a few bits and pieces and getting tempted by the idea of 197 injectors. Wondering if anyone has used them and seen a difference between them and stock.
Mostly because I want to get to the magic 200 mark and its been suggested as potentially helping it along. Got 4hp to find haha.

So is the group n timing on the 172 '6 degree and 4 degree' of the crank on the standard cams? Being ive Seen two claims one on that its 6 and 4 degrees to adjust it by. and one to that it was 7 & 7 degrees standard cams to adjust which I don't want to waste my time having to do it all twice or risk damage.

It’s 6 & 4. Inlet 6, exhaust 4.

Nice one for confirming that for me.
