Hi
as above this is to go on a standard 1275 midget
we can get hold of a Shorrock supercharger
now I think this was a standard bolt on mod in the mid 1960
or do we get hold of a turbo off a mini
we don't want lots of power at the top of the rev range
cos when you are half way up a snowy mountain
in Scotland you don't want to change gear and wheel spin
and fall in a ditch
a bit more about the car
it is my daughters for every day driver she is 22
but the problem is she is now into classic car rallying
she has just done Le Jog meant to be one of the hardest events in Europe
we managed to come 30th out of 65 starters
she has entered a series of events over this year
9 weekend events over 12 months
run buy the historic rally car register
and she calls me a sloth when the triumph TR4 or earl porch overtake us
on the transit sections
so all help most welcome
the only problem is the car is a 1958 Austin A35
thanks

turbo would be cheaper overall to install (manifolds/etc are more common) and upgrades to newer more efficient turbos is easy as pie. You'll also get more economy over a supercharger. But.... Superchargers are awesome Those literally are the reasons for either  |

You're like a crazy backyard genius! |

Be sure to check the regulations carefully if you use the car for classic or historic rallies. You might not be allowed to use some modern modifications.

I think you need to do bodywork mods to fit a supercharger, might be worth asking on A35 club forum as they'll be able to tell your the upsides and downsides of both methods.

Ah the Austin A35 club
you will see a article about the car and the event it has just done
in the next club mag also in the next issue of practical classics
If I ask in the club forum I will get the answer that a turbo is the only way to go I think you know who I mean

Fair enough and I get both mags so I guess I'll see your car. If you can wait till Friday/Saturday I'll have a look and see if I can upload the picture of the super charged A35 seems I guess your familiar with the well known turbo A35  Probably won't be much help deciding but I can see if my memory is right and you do need to modify the body for a supercharger. |

Go for the turbo and use MG Metro parts.

Wouldn't a turbo or supercharger put the A35 into the class upto 2l?
An other idea is to keep it N/A, a nice stage 3 head and carb can give around 85hp (with a engine character). Or rebuild the block and go to 1380 and a wilder cam to achieve 100hp (and a more assertive engine behaviour).

Apologies for how long it took me, some other things got in the way. But as promised, supercharger installed on an A35.   Hopefully you can see the bit of modification that took. Not sure what this is compared to that of fitting a turbo though as I presume they won't just drop in either with the limited room in our engine bays. |

a turbo can give more overall power but a supercharger is instant power from virtually any revs.
would avoid the MG metro setup like the plague - LAG LAG LAG
although the manifold might be useful if you did go for a turbo setup, though no doubt there are good A series turbo manifolds readily available
turbos produce heat - a lot of it.
this requires uprated cooling, intercooling and possibly some sort of heat wrap for the turbo itself (all dependant on the size of your engine bay etc)
supercharging however doesnt produce lots of heat, though an Intercooler is always a nice idea.
a turbo is more efficient thats true
it uses a waste product (eg exhaust gases) to produce extra power
whereas a supercharger is more of a parasite as its run constantly by the engine crank via a belt
personally I'm more of a fan of supercharging
its instant and gives a much nicer power curve, plus can be run on boost for long periods without adverse issues occcurring

Thanks OVY 871 just the sort of pic I need have you any more or do you have contact deatiles for the owner the charger is a eaton and i think it was a kit bountyhunter just the sort of answer i was after use this and why it helps give me a good understanding yes i am minded to go for the supercharger because of the way the power is delivered no big bang in the power curve to spin the wheels and catch you out half way round a bend or in snow so now I am looking for a smaller supercharger I think about 5 to 6 pounds of boost is all i am after I have seen these www.rotrexsuperchargers.co.uk/Rotrex/index.htmbut its £1500 just for the charger would like something cheaper if possible |

Is the charger on the blue one above an Eaton ?
Moss Motors usa do a kit in the blurbe it talks about it being a Eaton
I hope to get my hands on one in the next few days
just a borrow to see if I can fit in the engine bay
with out any cutting about I can only live in hope
Engine mods well as far as i can tell 90 to 100 HP
not a lot if i only run 7 pounds boost thats about 95 HP
if you wamt more then yes engine mods are needed
bountyhunter can you confurm this ?
Insurance
hear is the idear
insure the car for me with supercharger
go out and rally daughter navagates its the bit she likes
because its the hard bit
come back unbolt the charger daughter drives
and do it all again for the next rally
if i get it right it is not a lot harder than fitting a inlet manifold
and the insurer is happy with this
because at the moment its only old fogeys that rally
and with out new blood the sport will die

Not sure what supercharger it is but hopefully someone can identify it, and I'm sure 100bhp will be enough in an A35, good plan for removal and only on when wanted. Also don't worry us young ones are coming through, I'm only 19, not sure if your daughter would be interested but there's a group of us younger ones on Facebook if she's interested. Let you know in case she hadn't seen it. facebook.com/home.php?ref=m_notif¬if_t=feed_comment&__user=0#!/groups/180246272066778?ref=m_notif¬if_t=feed_comment&__user=0 |

Sorry if I'm teaching you to suck eggs, but I'd echo Waveman's comments. As a regular on the British Rally forum, there are always posts moaning about how restrictive the Historic regs are, for example you can't even fit an Escort Mk2 indicator switch to a Mk1! Unless it was a period mod, I'd be most surprised if it would be allowed - sorry to put a dampener on things. Be sure to check the regulations carefully if you use the car for classic or historic rallies. You might not be allowed to use some modern modifications. |
