172 cup rolling road with graph@174 bhp

[Fr05ty]

Just had a rolling road on the cup.

Was very happy with results. Only mods
Stealth cat back
Induction kit
RS tuner map
102k miles


Should I be happy or what you would expect with mods above?

Yep id be happy with that.

 

[Fr05ty]

Yep id be happy with that.

Thanks. I was at first, but then thought well maybe there's plenty out there running the same. Glad to know its a good engine.

At SRR, on a hot day like today, that's a great figure!

It's just a number, so who cares if it's 154, 174 or 204, it's how it drives that's most important, and now you have a benchmark so at least if you do make future upgrades or you just want to check that everything is still in the same ballpark then you know what your baseline was.

If you're happy then that's the main thing, I don't think you should be asking an internet forum to tell you whether you should be happy or not.

As long as it drives well that's the main thing. As budgie says it's a hot one today

I was asking as most long term members would of seen different figures over the years at different mileage, hence why I asked the question.

The main reason was to see if it's worth upgrading parts or not. Yes it's a figure but is it a good figure! I have my answer.

Wouldn't the intake temp be higher than the ambient normally?

I used to take part in a CS meet at SRR every year for about a decade. Healthy standard(ish) Cups always produced closer to book than others on those rollers.

 

[DaveDreads]

My 172 has the same mods and made 173 at the fly on a RR, so yours is perfectly healthy.

I dont get why some people say it doesn't matter if it has 154 or if it has 174?

Of course it does, the higher one will probably have better compression and be timed up correctly and generally be a healthier engine, even tho the one with 154bhp might still drive ok.

Obviously theres going to be a few bhp differences here and there but 20+ difference then imo theres something not quite right.

Exactly.

Why do you think that was? Larger inlets?

 

[Budgie]

Why do you think that was? Larger inlets?

No air con/better aux setup.

As above, some would also argue the 'hand picked inlets' story, really don't know the truth behind that.
