Robin Hood S7 Rear Suspension

Recommended Posts

Hi All,

 

About 6 months ago i bought a half built S7, Since i have been reading that the S7 are more work to get a IVA Pass. I will have lots of question but i would be greatfull if someone would give me advice regarding the rear suspension. the guy who originally built the car put coil over suspension which is great but would you have a look at the attchd picture and give me your comments as im not sure it will pass IVA inspection.

 

Thanks in advance,

Nick

I passed SVA with the same setup

An S3 passed IVA last year with the same

An Exmo is going through middle of Jan

There is no issue with this as long as its all bolted up solid with thick load spreading washers on the other side

 

The 4 bolts you can see in the photo, the lower ones need larger load spreading washers

These are the U clamps for the roll bar

You also need plates under the bottom of the roll bar to prevent them pushing through in a crash

As you have a S7 the seat belts attach to the rear of the boot tub, these are to low, a simple fix is another roll bar tube welded across the rollbar higher up which the seat belts loop over, this makes the roll bar the effective seatbelt mount and as such needs to be securely mounted.

 

Now your head will start to spin with the required mods to pass IVA but its not difficult

You need to look at the rear seatbelt mounting height

The seatbelt fixing plates behind the seats

The steering column support

Dash bottom edge radius

Boxing in the passenger footwell

Sharp edges

ive had a series iii for fifteen years, looking at pic i would suggest you strenghten the top angle iron bracket with another bolted underneath, as they tend to bend up over time, it was one of the mods to do

In the process of rebuilding my engine, nearly ready to fit just trying to decide which camshaft to use, I have been looking at the kentcam FR32 fast road. Does anyone have any experience with that cam or a better alternative?

I ran with an Fr32.

 

A very popular cam and in my experience a very good cam!

I had( still have) an FR32 in an injection head on a 2.1 with bike carbs, 130bhp

It's a good easy on the road cam that will rev to 7500

The injection head is worth 5 to 10 bhp

The cam rated at +16bhp

The Pinto likes compression so at least fit a Rheinz gasket (1.27mm) or the Felpro this will give about 9.7 to 1, ideal would be 10.5 to 1

 

People tend not to understand that more camshaft duration means the inlet valve closes later so the piston is further up the bore before the mixture is compressed, this has the effect of lowering compression ratio, so you increase static comp ratio to compensate

looking at pic of engine, have you a shortened sump, if not would suggest fit one before putting back in as ground clearance is very low on series 3

Thanks Snapperpaul for the info, my engine spec so far:

Standard 205 block from a low mileage Vehicle

Standard head which I have just had skimmed (to give a little more compression)

Felpro Head Gasket

Valves regrind/seated

New valve seals

New Newman camshaft followers

New Double Valve Springs

Twin 40 Dellorto carbs

Standard Sump

It will have a new Kent Cam FR32 (when I can afford it)

      Hi, im a new member and just bought a robin hood. On driving the car back, i noticed the coolant temp up over 120 deg. Sated! Seemed high. I stopped several times on the way home to let it cool. The seller had told me it ran hot, 100 deg he said!....not 120 deg! Anyhow, managed to get home ok. I assume the wind through the nose cone kept the rad just cool enough not to blow!
       
      Went out yesterday with my son. Can kept stalling in low gears and i had to keep restarting. The engine got hlt again, up over 120 deg so i tried to trickle home, but alas did not make it before the engine started smoking and i lost power.
       
      So 1 day old, my new dream car is stuck in the garrage! Really upset.
       
      Im no mechanic, in fact im hopeless with engines, so i need some help, any help! Is anyone on here local enough to spare me a couple of hours to help understand whats wrong and hopefully help repair?

      Sorned the car on Sunday. Judging by the weather on Sunday and today I may have been a little premature. Anyhow, I have started my winter project of replacing the rear shocks and springs. I have no problem with the mountings but wondered what poundage of spring to use and what length of shocks to go for? Any advise would be greatly appreciated.
       
      Also, while doing this I was wondering if I should fit camber wedges. I have heard mention of these many times. I understand the principal but could someone please explain what these are and where should be fitted? Is it worth fitting them?

      Hi. I'm putting rear wing on 2b, followed old videos exactly, I don't lik the large gap between wheel and wing. Does adjusting coil overs higher and lower car or just harden and soften suspension. Many thanks. Dave
