get'n the power downlow on a VR6

[tassie_euro_mk1]

Yep. I love the power on a the VR6. But i want it to come it a lower than 3200rpm.

I do understand that you can only reach about 190 - 200hp with normal mods. Needs a charger for more hp gains.

What are the mods to get more hp and get more on the downlow?

I have lightend flywheel, BMC CDA air box, and apparently it has a powerchip? but i know nothing about it and I really want info on this.
I need to put it on a dyno too. Im curious
yea. thats about it.

How about cams? are they worth it? ported/polished throttle body? Different chip?

Putting a shorter diff ratio in would definitely help, stock ratio is quite tall, made for autobahns i think Would probably be a costly exercise unless you can do the work yourself though

Interesting topic.. I am very curious too.

ZOOOOOOM!

You'd probly want a TDI 5th gear though to keep the fwy cruising rpm below 3k

shorter diff would work but I like the top end as well. I want best of both worlds lol. Might aswell bolt up a supercharger that would be soo cool.

In Performace VW or Golf+ mag it has a supercharged stage 2 VR6 Vento. Pushing out 250hp I think. still it only makes it up to 60mph (100kmph) in about 6.8 seconds. Now thats not that quick compared to volkswagens time for VR6's being 0-60mph in 7.1 seconds.


A shrick intake manifold would be good too... But whats the gains? hp and 0 to 100?

[Tim]

the gain is probly on 15HP up top. Its the low down torque u get that makes the difference. I have seen dynos with an extra 30nm at some points in the torque curve. 0 - 100 i have no idea. Its more about making the car more driveable.
A shorter diff wont make u lose top end unless you want to do 200km/h plus! The only problem is the above two items would cost a packet! especially getting the final drive gear installed.

I seriously considered getting the ring and pinion off you tim but alas I haven't the skills or tools to do it myself and I think the cost would outweigh the benefits if I had to pay someone else to do it

From my trip to the drags, we worked out that i should be doing 0-100 in the mid to high 6's, and i only have a pipe and CDA. if the vento can only do the same times with a blower and 250hp, why would you bother?
The blower must make a better gain on the golf, else somthing is going realy bady wrong.

[Tim]

i think u will find that with most boosted VR6s that traction would be a serious issue. I have trouble getting power down off the line without any major engine mods.

A vento is a bit heavier than a Golf don't forget also you have to look at other things than just a blower!

I know of a Golf at the moment in production which is hoping for about 170kw at the wheels his hoping to do 13s if not lower! This is NA and he is spending $10 000 on which I am helping.
