Rare Sight?

[RichValver]

Cant be many about surely?

 

[Silent_Scone]

lol, nice. Although the 172 is a Ps measurement so technically your OCD should be tripping balls.

awww so it is actually less then

 

[Silent_Scone]

Well the official number is, yeah. It's about 170bhp officially. Chump change in the grand scheme of things

 

[RichValver]

So been back for another run this year, slightly improved on last year. Only change has been a better filter is now on the car ?

Few more mods to be done for next year I think

 

[Crybert]

What’s the details on your car? Ie mileage, recent service?

Seems strange a fresh filter would give 6hp. They don’t give much power gains with items like filters

 

[RichValver]

Not

Not been serviced for ages. It's 135k currently ? well it had a random filter that I had laying about on it before so switched it to a ramair which I think feels better when driving atleast. Seems to show an improvement

Other than that I don't think anything has been changed since the last time.

How much of a gain is likely to be seen from a 182 over a 172 manifold. Is it actually 10hp?

[RichValver]

Before and after filters

 

[Hxrry]

Looks far nicer with the ramair filter, irrelevant of how it performs!

 

[imprezaworks]

The fatty/ktec looks the best imo.

 

[Daz...]

Decent results there, although I always thought that filters placed there are less effective than behind the headlight?

It would definitely help with heat soak at least.

 

[Simon998]

What're those on your topmounts?

Iv changed it again now 😁

What do you mean? They are solid screw on topmounts if that's what you are asking 😊

I can tell you where the extra power has come from. No doubt you've done the power run with the bonnet up. Massive reduces heat soak.

Unless you drive around with no bonnet, try a power run with the bonnet closed. I used to see this regularly in my saxo VTS days.

See vid mate, bonnet down on both runs 😊

My bad. I was sat in the physio's waiting room so I didn't watch the video.

So iv got another RR coming up this weekend, same place as the past 2 runs.

Upgrades since last time are a homemade decat 🙈 and a set of matched inlets/tb

Anyone want to guess the power?

I'm not too sure what gains these 'usually' give

186.6

 

[RichValver]

186.6

I'd be chuffed if I got near that

 

[jameswrx]

It’s obviously a decent lump as SRR isn’t usually a place for over inflated power figures.

But... it’s probably a waste of time comparing the two graphs on different days though isn’t it? Especially with the large temperature differential there. I guess it depends how accurate the DD temp correction is.

What’s surprising is the 9°c intake temp on an open ended filter that’d be sucking air after it’s flowed over a radiator inside an engine bay.

I'm no expert with any of this just find it Interesting seeing what the differences are. I think the run this weekend will be more of a comparison with the original graph as temps should be similar seeing as they are the same time of year 😊

 

[davo172]

If you run the car today and then again tomorrow you would see different figures lots of variables affect RR results bit of a lottery to a few bhp each way.

 

[Greeny.]

The de-cat will do sweet fa for power really, just add noise, the inlets will help slightly though, im guessing 182

 

[Greeny.]

I think hes just doing it for abit of fun, everyone knows theres alot of factors to duno runs and no one should really take them to seriously, but it does at least give you a rough idea if your cars down or power or not... probably.

This mate 😁 I know it's a solid engine and I just pop it on the Dyno for the annual rr day I go to 😊

 

[iimushroomzii]

I'm gonna guess 179.2bhp

I went there years ago (maybe 10yrs or so) when the late JGM mapped my sti. Was on a film studio grounds or something, is it still in same place?

No it's in an industrial estate now 🤷

[Martin_172]

181 next time id say.

While there will always be variances in RR's, running on the same rollers at the same place is as close as your going to get to keeping it accurate and getting to measure your results of your work! Looks like a strong engine that one, good given the miles just shows that low mileage isn't the be all and end all!

Ime high miles on a car makes a stronger engine if Serviced well

 

[Martin_172]

agree, but you always hit that peak where it peaks then starts to go down hill, just shows if well serviced that's probably not until at least after 150-170k!

 

[DomP182]

Out of interest what's the worst bhp figure people have had?

I've seen 140's-150's from ones with poor timing.

 

[DomP182]

Will Torque pro give a rough guide?

If this is the case I'm blaming you at Mallory 😂

 

[RichValver]

New inlets now fitted ready for the weekend , see if they make any "difference" 😊
