What sort of power will it push your Integra up to?

To about 280 bhp, at the flywheel.

Traction not really a problem till you get to 300bhp.

What are they standard merlin, 220?

Are you serious? My sarcasm detector isn't registering anything but you've never struck me as the kind of person who would read a dyno plot wrong

They seem to make around 215 on Optimax, atf obviously.

The peak power gains aren't massive, but what you're paying for is the power/torque curves getting totally re-shaped, to give a longer power band. That's what makes them quicker really - rather than the extra top end.

I followed around Donington a UK CTR - maybe it was stock, maybe it had some mods - who tf knows - anyway, I think it was stock because it was slow. I mean dog slow.

below 5000rpm looks much worse no?

merlin · 27 Feb 2006 at 16:22

Red trace is before and blue trace is after - big improvement all round.

Torque on left, bhp on right.

I couldn't see this mentioned elsewhere but surely...

Red is before, blue is after.

edit... FFS! That's twice in an hour

Yeah that was pretty crap. I went past him like the minis. Driver more than the car I think

Pug · 27 Feb 2006 at 16:51

dubious Dynos tho really...

i mean the torque curve has an axis which is deceptive - give the appearance of double the torque after, when in actual fact its around 20% increase (best case) still impressive, but starting the axis @ 100 instead of 0 amplifies the increase.

Also are they from the same engine as Merlins? Because the before HP is way down on what it should be producing in the first place, again amplifying any increase to be more than it is in real terms. Obviously if they are sourced from another car completely then my points irrelevant

Nice bit of kit tho Merlin

Power is at the wheels I believe

A stock RSX will make around 165whp, if it's lucky. This one seems to have made 170whp.

At stock - the K20 (in everything except the JDM CTR and DC5 oddly enough) also exhibits the same nasty torque dip before vtec engagement.

Only a stock K20 with a Honda map will have that Vtec dip - the remap and breathing mods take it out, every time without fail.

The figures stack up from my readings. Lots of tell tale signs they are solid traces with nothing fishy going on.

ah i see, sorry stupid mistake

Dogbreath · 27 Feb 2006 at 17:12

Makes you wonder why Honda with their massive technical ability gave the engine the dip in torque, it surely can't be accidental. My suspicion is that it actualy makes the car "feel" faster by giving more of a pronounced kick after VTEC has activated.

Dynapacks are at the hubs, not that it makes that much of a difference.

TBH Ive also thought that was the case, especially on the K20 where its normally such a flat torque curve. It makes me laugh when people on the CTR website going on about the amazing Vtec kick when it amounts to about a 5-10 ft/lb increase.

Er why?

left is Torque, right is BHP surely?

Bluey line is the 'after' and the other (lower) line is before.

*wonders whether it was worth reading the rest of the thread to see if anyone else has mentioned this...*

edit - yep, it would have been worth it...

Slime101 · 27 Feb 2006 at 18:12

oops - i thought it was before after not seperate torque bhp graphs!!!

Must read images properly before posting!

Simon · 27 Feb 2006 at 18:22

Dip is probably for emissions / economy on some standard OEM test

The Running Man · 27 Feb 2006 at 18:42

sorry that will cost well over 4k USD to achieve:

"Our stock RSX Type-S produced 171.2hp to the wheels as measured on a Dynapack dyno. The addition of an Injen Cold Air Intake, TODA exhaust manifold, TODA exhaust system, and the TODA Engine Kit increased power from the stock 171.2hp to 231.1hp. That's a total gain of 59.9hp gain over stock, while maintaining factory smooth derivability"

so factor in the manifold? thats like 500-1000 bucks, same for the exhaust, and what 200 for intake? plus the VAT and shipping.

and then fitting...

might as well buy a 200sx for the upgrade cost...
