Discussion
Im looking to get a new car around september. I have been looking at cerb 4.5s but have heard alot about reliability issues which is putting me off. So in comes the vx220t which I hear is very tuneable. My question is how much bhp would I need to tune the vx220t to, to make it as fast in a straight line as a proper 420bhp cerb 4.5.
Thanks in advance for your replies.
Thanks in advance for your replies.
Realistically you would need about 350bhp to match the Cerb in a straight line. This is possible but you will struggle to exceed 290bhp without major madifications. There are Speedsters around in Europe with 400bhp but the most I've seen in this country is about 330bhp and they have had issues with them.
Quarter mile times shouldnt vary much between the two surely - they both hit 60 in around 4.5 - 5 seconds although a lighter speedster which is easier to launch should get there first. Quarter mile times of around 13-14 seconds at just over 100mph I would expect aswell... where on our roads are you realisticlly going to need more power?
Blimey i think you would need to tune it to around 300bhp to match the cerb in a straight line.A stage 2 vxt with 250bhp will hit 60mph in around 4secs and around 10.5secs to 100mph,this would cost around £2k.Not sure what a cerb does 0-100mph in but would imagine around 9secs?So would probably need a stage 4 or 5 upgrade to match that which wouldnt be cheap!
I have a stage two VXT for sale on this site. Miltek exhaust and a re-map from Thorney Motorsports costs around £2000.00. Mine is making 240bhp and 280lb/ft. The torque comes in at 3000rpm and stays in a flat line until just under 6000rpm. The car also pulls 25mph per thousand revs in fifth gear. Next step would be a charge cooler which gives around 260bhp and 300lb/ft, or maybe a bit more. You would then need a Astra VXR turbo and a Sachs clutch to get it to 280bhp and 330lb/ft. That would cost about £4,500. and take it to stage four. All this info comes from the Thorney Motorsports site.Can't post a link but Google will find it. Thorney are official Vauxhall Dealers and are in Milton Keynes.
My stage two will hit 60 around four seconds. Never timed it to 100. It will blow an M3 away and has "suprised" a few of the German and Italian exotica around Manchester. Plus it gives around 30mpg in normal driving and makes a wonderfull noise. Only selling it because of illness. It will going in P/X unless someone wants an absolute bargain.

Thanks for the reply guys. Denno B, where would I go for a stage 4 or stage 5 upgrade and how much will it cost because you said not cheap.

If you're main concern is straight line speed then the vx is probabaly not the car for you. However if you do fancy one you might also want to consider buying the n/a and getting it supercharged, you'll then have the straight line speed of a tuned turbo with the handling of the na. Details are also on Courtenay's website.
Your right wmg100. Im interested in straightline speeds but I didnt want to go for the norm, i.e 10yr old jap cars. The fact the vx220t is light is why I am considering it because It wont need 700-800 bhp to do a 10sec run(or would it). Im going for something different thats why Im asking the questions now and to see how tuneable the vx220 turbo is. I have searched the net and I have found it hard to find high bhp vx220s. I have come across 300s but nothing higher. Is it that the engine cant handle it or people just by something else. Also are there any companies that would consider doing it. You hear of and see high powered hatchbacks(i.e punto gts, turbo civics, golfs etc) and the vx220t is lighter than most of them. Im sure it will give them a run for their money. Im still awaiting the sale of my car before I choose my next project, but if the vx220t isn't the way to go I will have to go somewhere else. I welcome your thoughts on what you lot think of a straight line high bhp vx220t. Im sure it would beat a lot of supercars, without the price of a supercar been spent on it because of its weight. Let me know what you think.

The problem with trying to get high bhp with the VXT is that due to the mid engine layout there are alot of problems getting the heat out of the intake charge hence why anything over a stg 2 requires a charge cooler to be fitted. The highest bhp VXT is steven kalssen's in Germany, who wirtes courtenay's maps, which is running at nearly 500bhp, but about the only thing left as std in the engine is the block!

There are some 1/4 mile times here: http://www.vx220.org.uk/forums/index.php?showtopic...
And details of Klassen's car here: http://www.type116.com/forum/viewtopic.php?t=1675
It would be worth posting your question up on vx220.org.uk aswell.

I think if your prepared to spend the £££'s your probably best to stick with one of the main two players for tuning the vx and as mentioned that would be courtenay or thourney.The highest level of tune would be thourneys 350bhp with 450lb of torque!I think this is classed as stage 5.Theres no price on the website but id imagine you would be looking at £8k+ bearing in mind the 300bhp stage 4 is around £6k.This would be a high safe level of tune and with that much torque added to the fact of it being so light would leave most cars for dead.To put in perspective how a stage 5 vx would perform i'll compare a tvr tamora's figures.The tamora has 350bhp with 290lbs of torque and weighs 130kilo's more than a vx,it will do 0-100mph in 9.1secs,that is lambo gallardo territory!So the 350bhp vx is going to be astonishingly quick,not because of the bhp though but because of all that extra torque,thats 100lb more torque than a sagaris and around the same as your ferrari F430's but without all the extra weight!So basically i dont think the problem would be how fast you could get a vx but more so are you prepared to pay that much to get it that fast!If your prepared to spend £20k+ on a tvr then it could be veasible to buy say a £14k vx and another £8k to tune it,dont think you would be dissapointed with the performance!
It seems I might aswell go for the cerb because 8k would probably get me more power from a cerb and it been already faster seems like its the choice for me. Mind you spending 8k on a car just to get 150bhp(I know the torque is very high), doesnt scream value for money, but I guess thats what you get looking for performance out of the norm. Thanks for the info Denno B, Im not taking the plunge into my next car yet but your info was very helpful and was the information I was looking for. Any idea of the quartermile for the 350vxt. I think mid to low 12s. whats your thought?

No problem mate,bare in mind you'll probably spend £8k on a cerb in a year on serviceing and the odd engine rebuild!I do love tvr's,think there awesome and I myself was looking to go down that road with a tamora or t350 only a matter of months ago,but there is that much negativety surrounding tvr reliability(especially the speed 6 engine)that i was forced to look elsewhere.I didnt want to buy a car that would have me thinking in the back of my mind when is this going to go pop!So the vxt with its reliability,plus the fact its so much cheaper to run than a tvr,servicing etc and tuning potential was what i went for.The tuned vx is still very reliable,although admitedly expensive to tune for what seems like little bhp compared to what you could do to an evo for example,but an evo would need 600bhp+ to match a 350bhp vxt.Id say the 350bhp would give 0-60mph times in the 3's,looking at 7-8's 0-100mph and quarter mile times in 11's maybe even less.Cant stress how important all that torque is,the bhp of a car is just a figure you throw at your mates down the pub,the torque is what will blow the opposition away.If memory serves me correct i think the 500+bhp vx did the quarter mile in the 8's!!Obviously thats lunacy tuning but just shows what can be done.in the 8s!!!! Now thats what I call fast. 11s for the 350b vx, Thats what a cerb mapped to 420bhp(what its meant to have in the first place) will do the quartermile in. Iwas thinking of the speed six route, looking at tuscans but the unreliability dare I say worse than the ajpv8 is why I was looking at cerb. But I still got months of research.
