only 150 bhp??
Discussion
hi all, i really fancy a vx220 na. but why only 150 bhp??? its a 2.2 engine!! years ago i had a 1995 honda civic vti that has a 1.6 engine that has 160 bhp!!! thats 10 years earlier. 150 bhp out of 2.2 is a bit weak dont you think lads??? im not dissing them just think its not much power from a 2.2??
all. Torque is what moves cars. I don't think a VX220 is right for you anyway.

But the 1600 Honda lumps need to rev to 10 squillion rpm to get anywhere and have such little torque that they struggle on slight inclines and head winds.
yeah i know what you mean, but with the vx being so light you dont need so much torque to move it. i know its at a normal state of tune so its going to be very reliable and have loades of torque. im into bikes (gsxr750) so i dont mind reving the tits out of an engine!! i like both!!!!bazzio said:

Probably to stop Vauxhall having an N/A car that would totally anhialate the Lotus Elise / Exige.
I can see it now......
Mr Vaux: Hello Mr Lotus, we have a 220bhp high revving lump that we'd like you to provide a chassis for and also construct along side your metro engined version.
Mr Lotus: Click, durrrrrrrrrrrrrrrrr

yeah your progably right, i think its a better car anywayI can see it now......

I think your missing the point. The 2.2 VX engine wasnt designed for a lightweight sportscar. It was built to shift Repmobile Vectras and Astras about. The Civic engine was probably specially developed for that car.
Anyhow the 2.2 is pretty tunable, Im picking my VX up in a few days and thats had a sports exhaust and rolling road remap and has 160 BHP (dyno printout to prove this). Next stage up has cams and gas flow head and adds another 15+ BHP. Not to bad for a shopping car engine!

PS. P4cks is well known on VX220.org and knows his stuff.

Fair enough Jap engines are a little different and yes, I'm impressed how they get 200BHP from a 2.0 in the CTR but in comparison to other vauxhall engines (2.5 v6 - 173BHP). Even Ford, VW and Rover etc... its about average, and because it is a recent engine, light weight torquey and timing chain'd it would probably be one of the most suitable engine for VX to put in the VX220.
Would rather one than the 1.8 K series in the Elise!

When you do get bored of the performance as I did, you can easily upgrade the engine, check out www.courtenaysport.co.uk they are fantastic guys and are the best in the business.
Sorry for the late reply I don’t check in here much
As mentioned above the 2.2 in the VX was designed by Lotus Powertrain to have a very flat torque curve in the mid rev range, which peaks at 155 lb.ft, primarily for pulling along rep mobiles. Where as most of the jap engines have a lot less torque and produce their power by running at high rpm, as power = torque*engine speed.
While power to weight ratio is quoted for how fast something is it is actually the torque curve to weight that defines how fast a car travels, as from Newton’s second law acceleration = Force / Mass and the torque curve is the force available as that point in the rev range.
Now one problem that has recently been discovered is that the inlet manifold while providing good mid range torque it strangles the engine at high speed, however the inlet manifold from the American 2.4 version of the engine solves this liberating another 15 -20 bhp for about £100-£150 and a power curve much more suited to a sports car.
