The most powerful Galant V6 ...

[RAVEN]

Who has the most powerful 2.5 24v V6 Galant here? What BHP are they running at? And what have they had done?

[zedy1]

turbo or not

Dont think theres much you can do to the non VR4 Galant as regards tuning , just the usual air filter , exhaust combo...

:rolleyes: nothing is imposs to any car if you got £$£$£$£$ "ie,nitro,supercharger,turbo'd are all poss but be prepared for an engine rebuild at some point i'm more into how it look's now (hence the GLS power)but uptill the galant i alway's chased more power and there are a lot of tuner's waiting to make there mark on something different all the time,and let's face it"the galant is something different"to most tuner's. :scholar: if i were on the hunt for more power i'd offer my car as a guinae pig to a good tuner and see what they come up with.

no no no ... I was only asking who has the most powerful 2.5 24v V6 (non-turbo obviously). I can't do major engine mods anyway as I'll invalidate my warranty. All I will be doing is de-restricting the airbox (if it needs doing ... not yet looked in the airbox yet), adding a panel filter, and changing my exhaust. I don't like air induction kits anyway due to them sucking in hot air and zapping performance.

Seems though the above was said ... how much power increase will I be looking at with the little tweaks made above?

And out of interest ... how much power increase will the V6 get on chipping it?

Anyway ... back to the original question ... who has the most powerful 2.5 24v V6 on this site and what bhp are they running at? What have they had done etc ... Just be very interesting to know is all.

I know the VR4 can produce huge amounts of bhp, but I'm just asking about the normal aspirated V6. ;)

You need to look at the BDA bean tin mod!!!! :-D

I went to see a local garage who do a lot of specialist mods for cars, including exhausts and induction. He looked at the airbox and feed for the V6 and said that a replacement panel filter would work just as well, if not better than an induction kit. He reckoned that the box would shield against the heat from the engine bay but the feed had a wide enough diameter to allow a good supply of air in.
He did say that a good mod would be to tweak the feed so that there was a more direct flow from the outside of the car (i.e. bonnet vent or wide diameter tube from airbox to space behind grill/bumper). On his advice I replaced the standard air filter with a K&N panel filter. I could be fooling myself but I think it has made a difference.
Hope this helps.

here are some before and after pic's i used to have a modded air box with a k,n panel,drilled box and added cold air feed from the front .now i have seen the light by changing to an induction kit,i also feel your local tuner "don't know what he's talkin about" as you can see "been there done that" and the induction kit work's far,far better, :p well on my motor?

Do they do Viper Air-Induction kits for the Galant? I don't really like the sound of an exposed air-induction kit cone to the heat of the engine. I prefer the cone to be in a heat-protective shell. I travel a lot in traffic ... stop and start and the such you see. Being in these conditions the normal cone will just suck in more and more hot air. And when I do need the acceleration, the hot air would foul things up till the cold air hits it again.

If they don't do a Viper, I think I'll just stick to de-restricting the airbox and fitting a Pipercross panel filter. Doing that on Vauxhall cars has produced more power then induction kits in Total Vauxhall Magazine tests. That proved to be true with owners of Astras in another club I'm associated with too.

[Big Ian]

i think viper do a kit for all galant's ,as long as you have a mas adapter you could use any induction kit that is big'nuff and wont restrict the air intake,also i'm pretty sure simon-who's car was in the jap,performance mag has a viper kit? try www.funkyproducts.co.uk for fillter heat sheild's and induction kit's or do what i done and get it from america.

But What About My Bean Tin!!!!!!! :-d

[Big Ian]

:end: IF YOU ARE USING THE BEAN TIN AS A FILTER I RECOMMEND YOU COVER IT WITH PART OF LADIES TIGHT'S :lolz:NO THE GUSSET BIT AS THAT WILL RESTRICT THE AIR FLOW :nono:

[enigma]

No no no no no!!!

Looky!

[Big Ian]

are you using it for a heat sheild

[enigma]

I am using it to bridge the gap between the standard scoop pipe and my £25 X Power air filter........dont want that nasty hot air getting in! I originally lost about 20hp when I fitted the filter, but the bean tin restored that lost power!!! Beans beans good for your heart!!!

Daves a skinflint !! he used sainsburys baked bean tin !! I used fortnum & masons !! :$ :$ It works though !! :-D

[Big Ian]

nice one dave sorry about that tight's bizz! :noshake: check my cold air feed hose on my £6.00 filter :wow: it used to be part of a hoover :thumb1:

[enigma]

It will still suck in warm air though? You need to put the whole lot in a cone, and then feed it with air through the vac hose!!!

[Big Ian]

i'm going to make a heat sheild in work,do you think this will be ok or should i try and enclose it more?

Who has the most powerful 2.5 24v V6 Galant here? What BHP are they running at? And what have they had done?

I got 140bhp approx at the wheels on a rolling road last year which equates to the standard power figure at engine - autos dont give precise engine bhp figure apparently.
car is standard v6 sport with no mods (yet??)

i reckon standard v6 will pump out 130 - 145 at the wheels, maybe more with induction / exhaust the next thing to go for would be a dastel unichip but they are about £400

[Big Ian]

so rich is you keepin it or not?

[ritch_w]

yes i is (unless someone wants to swap a mint vr4 for it??) :D :D

Ive just renewed the insurance etc and will be getting the door damaged fixed when i get home from the states.

BTW seen quite a few 8g's today quite a few of them have what looks to be vr4 type spoilers, loads of Diamontes as well which i think are like the austrailan magna (or Magma?)

been driving about in a nice Lincon Continental Deville 4.6 V8 :rolleyes5 :rolleyes5 :rolleyes5 makes a nice change but prefer the Galant!!! :-D :-D

[Big Ian]

you should try and take in a cruise somewhere an take lot's of pic's? and try get yourself a spoiler out there it be a lot cheaper :-D (big hand lugage though :rolleyes: )

Really? I thought the 2.5 24v V6 ran at approx 158-161 bhp standard. Top speed @ 137mph with a 0-60 in 8.2 secs. This is what is specified in Car Magazines ... in particular TopGear and Auto Express.

My old Calibra was dyno tested at 153 bhp and my Galant feels faster then that.

There's a hill with a swooping bend I use to test the power of a car as well, and in the Calibra the speed I managed to get up to by the time I got to the top of the hill was 50mph. In the Galant that speed was 60mph.

That test is not precise and I'll be sure to get a dyno test done of the Galant to compare figures with the Calibra I had.

The magazine specs 'feels' about right though.

those are the "engine" or "flywheel" power readings which the operator who dyno'd my car said would be correct for 140bhp at the wheels, given that the car has an automatic transmision which will loose some of the power.

Most Dynos will give you 2 readings;
1. engine power (at flywheel - which is what manufacturers quote - as this is the big number!)

2. Power at wheels which is the real life power figure that your wheels are transmitting to road after the drive train etc has robbed its share of the power

also some dyno operators "aledgedly" calibrate their dynos to give higher at wheel readings so that people are not disappointed when their quoted 130 bhp car only makes 100bhp at the wheels........

My 2.5 v6 made 149.8bhp and 149.6lbft on John Nobles dyno with an induction kit, de-cat pipe and full stainless system. With a Unichip as well as the other mods it made 154.3bhp and 155.8lbft, not a massive improvement on peak power, but the torque lower down the rev range was up by 40lbft in places, and as we know it's torque that accelerates a car. I also have a gas conversion, which uses a venturi style collar near the throttle body, and both Darren at Nobles and I believe that this may be restricting power. Also the pipe that joins the manifolds has a very sharp bend in it, and I plan to replace this with a less restrictive version soon. On top of all this I have a nitrous kit that has given an extra 50bhp, and that really makes a difference. I have also fitted Tein coilovers, uprated anti-roll bars and a big brake kit. The reason I mention these is that they are worth more than an extra 20bhp, as they allow you to use the car more effectively.

[ritch_w]

neil & Bob - any pics of your mods?
which stainless exhaust& induction did you fit?

[zentac]

Is the standard 2.5ltr V6 a normally aspirated 6A13 engine? I know mitsi made a NA 6A13 as Ive seen one transplanted into an FTO. If so its almost identical to the 6A12 in an FTO which rpw in australia have just produced a turbo kit for, which might be work looking into.

[neil and bob]

Ritch-w, the exhaust is a powerflow thing, if I had another it would be a real jap one, in fact I may still change it. The induction kit is a homebrew, made using a FK filter, these have a shiny cover around a conical filter, with cold air being vented from the standard place in the grille.

[neil and bob]

Ritch-w, check your e-mail, with any luck you should have a couple of pictures, forgive the quality, they were taken with my phone.
