197 tuning options

[Dan-88]

What sort of options are out there for some basic reasonably cheap (not thousands of £££) tuning mods for my 197? I know it's quite limited being Nat.aspitated but surely there's stuff out there.

Doubt it. Theyve already managed to squeeze out 20hp more than the same block on a 172 so without major mods your not gonna get much.

Induction, decat and remap I bet is your lot.

 

[Typhoon]

Yeah as above. Without turbo'ing, sticking a meg engine in, ITB's etc.. you're not gonna get much more juice than it already has unfortunately.

Timing adjustment will probably be your biggest gain, advancing the inlet cam a few degrees. Followed by a remap to suit with a slightly raised rev limiter.

I'm intrigued, I've not heard of that before, even on 197.net. Is there many people that have done it on here?

cams, exhaust manifold, decent exhaust...

Similar to what the rally engines do really. Group N timing I believe.

Is this with a upgraded cams?

I'm sure you can do it with standard cams can't you @NorthloopCup?

I've been looking at bolt on direct to head throttle bodies but can't find any for the 197s, any ideas?

Not really sure on bodies for these.

Isn't that on the mk2's?

Jenvey will do some but for the money it really isn't worth it, some guy on 197.net put over 10k into his n/a engine....

I'm sure Mark's 172 Cup was a 172 block with 197 head and cams which was timed up to group n spec.

Interesting, I'll have to try and find some info on that, technically free power right there.

There were a few Group N 197s so I wouldn't be surprised if some timing changes are possible.

Nah that was the original engine mate. The hybrid was dialled in on the standard marks. I've got a cam tool for the 197/200's but you also have a different cam to fit. It ain't 'cheap' horsepower either if you get me!
