supercharger/turbocharger *one for the engine builders*

[richglanzav]

hi i just wanted to ask, a 4efte is obviously built for a turbocharger we all kno that and with its forged internals installed etc it can handle huge power.

but has no1 ever built a supercharged 4e engine?wud be an interesting change...i think it was jamesbaa or sum1 on ere posted up pics of his trackday and his mate had a supercharged swift gti, bout 200bhp? so its obvoiusly possible.

so lets just say i had a forged 4e engine fully built etc. how much boost cud i run on a supercharger and what would you expect it to be like in a glanza or sumthing? or has any1 twincharged a 4e? is any of this even possible? i dnt know hardly anythin bout the mechanics of a supercharger, so wud a forged 4e take big boost off a one the same as it could from a big turbo, e.g. gt28, etc.

id love to see a glanza or GT with big power but supercharged, with the whining sound they make under power.

supercharger robs engine power to operate hence usually suited to larger capacity applications. it might work if you could twincharge like the new vw small capacity engine but would be complicated. obviously the point would be that the supercharger brings the engine on boost quicker. not worth the hassle i say.

problem with superchargers is the bigger/more you under drive the charger the more power it takes away from the engine to generate the extra power, so gains are minimal compared to the turbo options. twincharging would be an option to get round some lag, with a electronic clutch on the charger pulley so it could be disengaged at say 4000rpm and let the turbo do the rest, but its a lot of effort lol

it can be done, and ive had a shot in car thats had this done as standard, the micra superturbo, 930cc, and by does it shift, but there is all sorts of problems with it(well there was one the one ive had a shot in) but it shows it can be done on small engines

it would cost a small fortune,personally,i think its a waste of time on a 1.3.

you know and i know and everybody knows its pointless lol if you desire the noise buy a type R and s-charge it.

a goal of 200bhp and almost zero lag?

what about cams and a ct9 at 1.2bar? laggy? i think not.

I have seen a pic of a twin charged 4efte i think i have a pic somewhere.

 

[Dan3SGTE]

yeah it does sound pretty pointless. It is different but is it worth the money on a small engine? I think 200BHP would be fairly difficult to acheive from a 1.3 boosted by a supercharger. ALot of work would be needed.

Boost, well boost is boost weather its from supercharger or turbo. So it will take what ever the engine will take. Forged, then more then any supercharger will be able to phisically boost.

+ side superchargers generate less heat then a turbocharger. So reliability would "probably" be better.

my bro's polo g40 is pushing 208bhp and thats a 1300cc 8v we are just rebuilding the motor now with forged internals as it was running stock at 208bhp, going for more boost this time too.

superchargers are excellent for producing lots of torque. yes they do sap some power but theres always a loss to a gain, turbo charger's have lag, thats their downside..

 

[sx_turbo]

nothing wrong with super chargers, in comparison to how much power they lose they give much more.

superchargers are like turbos, if you have forged internals, pretty much run whatever boost you want (providing the compression ratio's are sensible)

 

[GP82]

Get rid of the 4E, do a conversion with the Lotus Exige 1800 supercharge engine, which is a Toyota engine available in 240 - 260 - 280hp package. Boost from 2000rpm to 8000rpm!

 

[Beaker]

Ive seen a Mk1 MR2 that had a twincharged 4age. It had approx 300 bhp and went like shit off a shovel. Sounded amazing as well. There were some vids of it. I will stick them up if I can find them, the noise will convince you that its worth doing.

 

[billzisia]

You mean something like this:

But with the turbo on too!!!:rockon:

 

[Fro]

My mate had a supercharged 106gti, 201.3bhp atw on a rr printout and by fuck did it go.

was it white?

 

[Fro]

aye, It was my mate that brought it up here from Hamilton about 3 years ago, had it on the road a couple months and, iirc, sheared the keyway on the bottom pulley? A mess anyway, then it sat for a long time, he sold it to another mate who then sold it to the boy that use to go about inver in the black gt (that you bought?) But supposedly its running a standard engine again?

What a long winded story! :homer:

 

[dantheman]

superchargers are obviously limited to what boost you can push through them though,just like turbo's are.. spin them too fast and the can blow up in a spectacular fashion :haha: also there are different types of chargers that have different characteristics ie. different power delvery. much like different turbo's do. so you need to find a charger thats suited to a small displacement motor.. an eaton m62 is a good size charger (commonly found on bmw mini cooper S) i ran one on my old 1275cc mini years ago and it was pushing around 156bhp at around 12psi. couldnt get it to run 100% on the carb's though.

2bh the idea of a supercharged or twincharged 4e engine in a glanza wud just be to build sumthin unusual and still fast. and there ya go 208bhp from a stock 1.3 supercharged. if ya get anymore power from that i dnt care what any1 says surely that wud apsolutely rape a td04 starlet say round the bends etc with the instant power?

 

[jamesbaa]

It was me who mentioned about my mate with the superchaged swift, its running a rotex supercharger so it means it is 99% officeint meaning it doesnt sap much if any power from the engine!

He has had it mapped and its making 205fwhp and that is with a 75mm pully, he has a 60mm one that he needs to do some calculations for but that will be going on next.

fun fun fun

A mate of mine has a polo G40 and feck me does it go!

Power is there constantly, which is evident being supercharged. But it really shifts without any lag what so ever. But when the glanza is on boost the story is mutual

Ninja1270 on here has seen the beast, not many G40s left at all.
