250 KTR Induction and RS Tuning custom map - What gains have you had?

Induction kit give very small gains on stock car.But on a map car there is a gain of 5 to 8 bhp and up to 12 if you are running hybrid.
The car will not be any smoother running induction kit.

 

Mostly just noise, on a standard map the car doesn't really make use of it. Even with the map maybe 7/8ish extra horse power, I have always just used a panel filter as the original intake is so well designed.

 

I have the ktec induction kit on my 250 and it does pull a little better. Although i think it would benefit from a map to really get the most out of it.

 

I have a piperx panel in. Little bit extra noise and car sits cooler in traffic. Either way both options are better than the stock filter.

 

Save yourself £250 by not bothering with an induction kit and putting the money towards your Remap.

I have emailed every company that makes induction kits for the MK3 Megane RS asking for proof of gains, none have been able to provide me with any which indicates to me that they are just very expensive noisemakers.

You should easily make 300 BHP with a map from RS-Tuning.

 

Paul at RS tuning told me a few weeks ago that they tend to make a bit more power with induction when mapped. Mines an R26 though not a 250/265.

 

KTR offer this as their performance pack. I had it done along with new exhaust and the gains were huge. Ran 6500 (ish) miles since having the work done and it's been a dream

They did have to install new spark plugs though due to misfiring

 

I had stage one at ktr awesome smooth pulls hard above 4k and temp not altered even on track

 

Morning I did the RS Tuning route Turbo back exhaust sports CAT, induction kit, intercooler and custom map turning out 306 bhp all usable very smooth delivery. I have had a few years ago a generic plug in remap and that was brutal seemed like the boost was too high. Whatever you do get the custom remap totally worth it. In hindsight if you are happy with the noise of theOEM exhaust just a remap and a better filter which is what many people on here say. Should get 285-300 possibly with that alone

Hello :-) I had my RS250 at RS Tuning towards the end of last summer. Stock it made 264bhp / 280lbs. With the map it made 300 / 348 and has run like a dream since then, highly recommended. Michelin Cup 2 tyres recently added help with traction issues on straight line acceleration in 2nd due to the extra torque (non cup sadly)

 

Genuine question: Is this discussion (along with most others relating to peak power output in this forum) claimed flywheel power?

If so, why? Considering that you wouldn't accurately know unless you put your engine on an engine dyno as opposed to a chassis dyno. Why not use the measure at the point of measurement? The tyres.

 

Because the flywheel numbers are bigger?

 

it's because people understand flywheel figures in relation to factory quoted numbers. it's a ballache. I have a mustang awd dyno that reads at the wheels. the only proper reading for a chassis dyno. anything at the flywheel is clever calculations assumptions and estimates through software etc. I have seen people massage brakes on run downs to bump people's figures on some dynos and as with anything like this it can be exploited. but I always look for whp reading. it's the closest dyno to dyno comparison there is.

I also PMSL when I see a before and after run show 40-50hp increase but the drive train losses increases 20-30 hp from stock to modified dyno runs lol.

net gain only 20-30hp in real terms lol
