Turbo or G60???

Recommended Posts

I've just had a look on the EIP website and seen a turbo conversion for the G60, I know it's been round a while but has anyone had their G60 converted to a turbo? Just wondered what it was like? It's crossed my mind before just for the sake of mental power, but now I'm looking at 1.9 bottom end with X-flow head and a few other bits and bobs :twisted:

What do you lot think?

Cheers peeps

I knew of a MK1 G60 that dumped the G Lader in favour of a turbo. It churned out somewhere in the region of 250bhp if I remember rightly. It was mental.

Depends what you use your car for. Superchargers give nice torque and pull at low RPMs and don't have any lag. If you spend a lot of time on race tracks or the highway maybe a turbo is for you, but it might actually feel slower driving around town.

TURBO..

 

Every Time ... sorry you g60 owners those ladders scare me... I'm to paranoid i think ... it all depends on the compressor your run.. you can get a real small turbo that will spool up as well as a ladder..the turbo technology has really moved on .. try the new gt range from garret its just as good as the ihi gear and has a lot better flow the old T-series .. they a bit old hat know.. plus you don't need to rebuild them ... just bolt up

and just play the evcr

(new to turbos/superchargers)

 

I thought the supercharger was the better ? (not reliability ) or is that just at low speed high acceleration ?

 

/me goes to do a google on supercharger theory :oops:

turbos provide more airflow that a supercharger at any given level of pressure(boost) a 10psi turbo will outdo a G60 in all but the smallest turbo's. Turbo has some benifits. for example a turbo is less prone to destruction in most cases than our G60 so more power can be extracted. problem is our engine doesn't particulary lend to a turbo. with the head being counterflow the turbo sits a tad below the inlet manifold and close to the firewall. this causes heat and clearance issues. downpipe/manifold problems are a biggy too. the Glader does provide a more seamless power delivery with more lowdown torque but this can be counter productvie once the boost is upped on a glader-wheelspin.

 

id have to say im thinking about it. the Glader is good but i too am a tad sceptical about its reliability on the 65mm im on. does sound like its screaming at 70 now.

 

the other thing is lag. dont happen with a glader but does with a turbo. my feeling on this is that you only see the lag for one gear or a cog down. once your in boost your there and stay there so that wouldn't be a problem for me.

Well Andy to be honest I'm bias as i'm running a turbo ..

Whats wrong with running both?

 

can be done and its done but its tricky controling all that boost. A 20v head with a supercharger spooling up a big turbo would be a real weapon :twisted:

I can't remember what car it was for, but I remember reading about some American nutter who made a super-turbo-charger setup for his V8 while I was at Uni doing engineering... :shock: The whole idea behind it opened my eyes a bit! :shock:

 

IIRC, it used a pressure sensitive valve and an electric clutch on the supercharger pulley. Upto about 3000RPM it was supercharged, with the turbo-boost being vented to allow it to spin up with no back pressure. After 3K (when the pressure valve decided it was time!) the valve flipped over, dumping the Super boost to atmosphere and directing the Turbo boost to the intake. The Supercharger pulley clutch was then electronically activated a little bit higher up the rev range so that it didn't spin to destruction while the engine was running on the turbo... 8)

On the way back down again the supercharger was spun back up to speed just before being needed and there was an almighty dump vlave in operation after the change over valve so that all of the boost could be dumped during braking to prevent both the S/C and T/C being slammed to a halt, or burning out the brakes due to still being under boost! :shock: :lol:

 

I remember figures in excess of 1000bhp being mentioned! :shock: Sound interesting?!? :lol:

to do both u would need to run some kind of clutch mech on the g otherwise it wouldn't last long especially on a multivaulve head that can rev freely

rob kisby is doing this at the mo using an eaton charger and a monster garrett gt he will get huge power from this

 

 

sorry henny i should of red your post first i seem to have repeated you...

is it not like comparing chalk and cheese?? both of them give tottaly diff driving experiances.

A friend of mine has a scobby and it is quite a beast when it comes on boost but is no where near as smooth or as balanced as Leia. The VR6 I imagine would give similar performance to the G60 for smoothness?????

 

 

PL :D

having come from a turbo escort with 183 bhp at the wheels i can honestly say that at the mo i niss the turbo kick.

which is best is a real choice as both are so differant to drive

if you want to have both on the same car then speak to chris todd at power engineering, he has a mk1 fiesta witha 1.9 cvh lump running a charger and a turbo, mental stuff.

i like me charger but its gonna take a lot to make it as quick as me turbo. at least its bootable in the wet as power is smooth, a escort turbo on a wet road is spining everywhere.

at donnington i couldnt keep up with a mk2 golf with a standard 2.0 in my escort, they were a lot quicker out of the corners.

power up to 90, a charger, more then 90 a turbo everytime

so.. say you had a pulley at 65/68, with no other mods except mapping, whats the top kind of speed ? PLS tell me its a hell of a lot higher that 70 !!

i run a 65mm with red tops and SNS and a frontmount. i have a 2.25" straight thru with no cat and a induction kit.

the tone has changed on the charger. the gearing is ther same so speeds are but it accels a lot quicker now.

 

i had a test last night. me and a mate were going to a friends house. he was following me when i came upon a mk4 Gti. anyway blew him off without any hassle. the difference was so much he gave up at 60. anyway we carried on as before the tune his car was faster than mine. he has a legacy turbo running no cats and 3" straight thru with induction kit doing about 13psi, probly 220-240hp.

coming off a roundabout i hit the throttle n started to pull away. not a lot but it was pulling. hit 4th n at about 4.5k it went BOOM like a balloon n i lost lots o power. he shot up behind me v quickly, id popped a boost hose off. now itll hold 16psi in third so not sure what boost i get in 4th maybe another psi or 2. enough to loose a hose.

 

 

think its time for a cam and some better brakes.

exturbo2003, How come your G60 is bootable in the wet? I went out in Brookecourts G60 Friday (which I have now bought:)) when it was wet. I had no chance of any traction up until third.

 

That wasn't from booting it from stationary either. Pull off nicely..press my right foot down...wheels spin...change to second...press my foot down..wheels spin :shock: God i've missed driving a G60.

 

Second thoughts maybe I should of checked the tread on the front tyres before giving him a deposit :D :D :D

Mine is the same, can be driving along in the wet, 3rd gear, floor it, and the wheels just spin the night away. But in the dry... :twisted:

Hi! I have changed the G-ladder on my corrado to a Garret T28 turbo. The thing you do notice is that there is less pull at the bottom of the revs, although once you reach about 3000rpm the turbo takes over and it is well quicker from there on in. The pull down low was increased by using a Apex-i boost controller,(Don't use a bleed valve - your only asking for problems, especially when the spring weakens) so that i can change the duty the turbo comes in at, the boost level it will run and rev at which the turbo comes in at. After that i got Jabba to set it up. Since then it has been a different car!!!

The new problem is wheelspin, i have fitted the Quaffe Anti torque-bias (LSD in old money) and had the gear box completely rebuilt although it will still spin up the 17 inch wheels in THIRD!! (even worse with the 15's).

I would recommend the turbo if you are going to be thrashing it up the 1/4 mile or using it for long motorway driving or a suppose blowing the fuck out of most of the cars on the road, but i do miss the bottom end grunt. I can only use 50% of the throttle about town and even it that you are tramping it along!!!!

its a 50/50 split depends on what you want to use the car for. :lol:
