to supercharge, or not to supercharge that is the question?

hi everyone,
im after some advice on my 2.0l GTV its getting decleared off the road at the end of this month and wont be back until the end of summer. whilst its off the road im saving up and was thinking of getting autodelta to supercharge it, im looking to make my gtv very quick and wondered if this was the easyest most cost effective way of doing so? what do you think? any ideas on how i can go about getting +200BHP whould be appreciated, and any bad points about superchargers would be helpful to. thanks sean.

Sell it, buy a V6. Cheaper in the long run. Probably not what you wanted to hear like..

Re: to supercharge, or not to supercharge that is the question?

i agree with Pud, sell it and get a V6. thats the easiest, most cost effective and best sounding way to get over 200bhp
seriously, give a V6 a go and you wont think about going back to a TS

You can still keep you car and put a V6 into it.

It will probably be cheaper to convert, run and easier to sell. Noise, handeling and all the other factors are your choice

Edit the bad point about superchargers are that there are very few specialist so so might have bother finding someone to refurbish it etc. There is no lag or sudden burts or power unlike turbos. I'd prefer a supercharger to turbo thb. Don't quote me on this but you don't need an intercooler with a supercharger either.

Re: to supercharge, or not to supercharge that is the question?

Slightly a killjoy comment coming up but it is just my opinion

how many miles has your TS got on the clock? I think over a certain number Autodelta won't do the conversion.
+ it's about 4 grand, you could get a fairly low mileage V6 for that and then spend the money from the TS having the V6 tuned to 250 !!

Re: to supercharge, or not to supercharge that is the question?

Definately showing signs of attachment, I vote charge it... Its your money and the v6 is nose heavy in comparison to a TS

Re: to supercharge, or not to supercharge that is the question?

Problem with a super charger is that it robs the car of power ... possibly better to go for a super charger ...


... but then if you "only" want 200 bhp you should relatively easily be able to get this just be changing the CAMs/getting other work done ...

EDIT: just noticed you're in surrey, best thing for you to do is take your car to AHM, tell Adie how much you want to spend and he'll get more power out of it than Autodelta can ...

Re: to supercharge, or not to supercharge that is the question?

Supercharging may not be the answer; I'm not sure the engine will take it and not fall apart - and yes you may lose low end power and it would be very expensive.

Possibly the easier cheaper way to do it is get a stainless steel custom exhaust (~£250 - £500) induction kit (someone has already designed one for your car I think, my mate has one on the GTV 3.0 and got a big gain ~£200) and a dhip/remap from Red Dot or similar (~£200). Then fast road cams are apparently a good thing, not sure of the cost. Anyway less than £1500 all in which is much cheaper than a supercharger and you're less likely to suffer a catastrophic engine failure. Should get you close to 200bhp with no lag at low revs.

Yeah... but if he sticks a supercharger on it, we'll have more fun reading about it. Chips and filters etc. is a bit boring by comparison.

2002 GTV T.Spark

Re: to supercharge, or not to supercharge that is the question?

Autodelta Supercharged T.Spark= 230bhp. Oh more power than a V6, without all that weight up front V6


It is very expensive though, i like my Twinny but there are limits.It would probably be best to get a V6 if it's power you want.

Re: to supercharge, or not to supercharge that is the question?

...or their turbo!!

Autodelta Shop

225hp, but a mountain load more of torque than the s/c I imagine.
But first off you should give them a bell and find out if they'll do anything on a 66k mile engine

Re: to supercharge, or not to supercharge that is the question?

I'd say 66k is too high for supercharging, unless you have owned the car from new and know that it has never been run low on oil etc. I am looking at doing it but i have a reconditioned engine which has done 15k so far. My old engine blew at 75k and am glad i hadnt spent any money on tuning it.

Getting a V6 isnt an option as i'd never get one to handle the same + there are no selespeed GTA Sportwagons around anyway.

Also its good to be different. 4 Grand is alot of money yes, but if you are keeping the car for a long time why not.

One issue i have is insurance. What happens if the car is written off, are you likely to get any of the money back for the supercharger add on? This is if the insurance company knows about all modifications of course.

Re: to supercharge, or not to supercharge that is the question?

Saw that yesterday,

A very nice car, but the owners made the mistake of selling it.

Probably worth less than a third of that price

Poor guy, sounds like he really needs to sell it - he won't get nearly what he's asking for though, I fear. What a lovely job he's done, very tasteful. Somebody will get a bargain.

I was with greenlight insurance for a couple of years, they're pretty good for modified cars and have a "like for like" and "agreed value" policy so as long as you declare everything and tell them what you think it's worth you'll get everythng back should anything happen

its always been dealer serviced up til i bought it, now i service it and metain it as i work at a x-alfa dealer. befor i bought it, the cam belt had snapped and the entire top end was re built so it runs like a dream with perfect oil pressure. i think its worth doing and am proberly going to scrape togeather the money for it.

Re: to supercharge, or not to supercharge that is the question?

I just hope your bottom ends ok after that cambelt snap Sean, But i'm sure its gone ok so far since so probably ok...so why not?!

I'm sure AutoDelta inspect the engine fully before going ahead.

Got a huge list of stuff to do myself before i think about getting it 'Autodelta'd'. 330mm disks and LSD come first

I don't think the engines are opened up. If you are charging an engine, any weaknesses will give way. Its a 'bolt-on' kit, designed that way so in theory forged internals aren't needed. But if there are any weaknesses already in here, they are obviously going to go. But it isn't AutoDeltas fault if the engine is already quite worn out.

If you were going to do this, I'd fit a new set of big end shells first, just to be on the safe side.

Re: to supercharge, or not to supercharge that is the question?

Suppose that even if the engine does give out afterwards you could get a recon engine fitted cheaply by another garage and the supercharger would be a simple swap?
