Holmes Racing - MGB MGC classic car racing

UPDATES 




The MGC alloy head updated casting has now been heat treated and is on its way to the machine shop. Plan is to machine on the new CNC unit and this should be the final form for all following heads. 
The main problem was wall thickness around the plug, the walls are thin even on the cast Iron head so for the first test head I used a 10mm plug. We have increased the wall thickness to the maximum without spoiling cooling round the plug. 
We intend to continue to use the 10mm plug which comes in all heat ranges as required for longevity of the casting this is the way to go. I am sure that at some stage someone will over torque a plug and will need to repair, the extra meat around the plug will allow this.
A new set of valves has been made for us to use which will be a nice improvement in flow. 
The amount of effort involved in bringing a alloy head to the C community has been huge on all parties from Steve and I to our caster, machinist and finisher. In taking our time to get it right we will ensure that the C will have a replacement cylinder head for many years to come.



Vernier Cam gearfor the C a must for getting cam timing correct. New small batch has arrived in stock.
£156 +pp







A mock up of Wilwood callipers and vented discs is in progress new discs  made in NI for us. Hope this will replace the Jag callipers and rusty redrilled discs on the Yellow car.
Steve Curtis has rebuilt the king pin/stub axle for me and next stop is replace the torsion bar bushes. 



























































The Alloy head is running well no issues and with over 1500miles now. The pattern has been adjusted to allow some more material in certain areas that we thought was needed. Casting will take place of one head and machined on a new 5 axis CNC which is now installed at 
Final finishing will be done by Darren at 





The head has been fitted with no issues, great work from the machine shop to scan the head and machine it to such tolerances that every bolt fitted first time.
We have done a couple of hundred miles so far with revs and driving over a range of town and dual carriageway work, raving up to 5000 rpm +
We have fitted a modified Dizzy to help use the head to its full potential on a standard car, a upgrade I can throughly recommend. Supplied by Steve Curtis.

Included is throttle arm and BSPP vac hose adaptor.
£525



Alloy Hubs 


One set left. Fitted with studs 50% weight saving.

£480 including new bearings.
The hubs are made mainly for racing guys with the weight saving on the front suspension but as the original hubs are becoming harder to find in good condition this gives an alternative to replacing those wires with Minilites (less maintenance). Weight is 1.296kg compared with 3kg .




Alloy Back plates.

£306 another few kilos off.
Only two left as of March 17.



Something a bit different from SC a twin cam Mini 1380cc

Very nice 150hp available with compressor or turbo

Snetterton Weekend Racing in the Rain.

Connor's second ever race outing once again in the wet, in a strange car to him. he has changed from  a FIA B to the MGC. With car not really set up for wet and some dodgy Steering geometry (went round right handers ok , not left ones)



Nice drifting by many, in the PBIC I think all came away scratch free even Jonesy! who I think retired early to preserve his P38 (plastic padding or bondo.)

One less fortunate in another series suffered no one hurt though.





.Another MGCGT has joined the collection. 
1968 steel wheel car restored a few years ago and still very nice in its blue coat.


This one of the cars for MGC 50 we will be taking along and hopefully two more.

New batch of Alloy radiators have arrived in stock I have a couple of black sprayed ones if anyone wants one not so shiny. £187 + pp 

Steve has a number of half engines/blocks which he is contemplating weighting in at the scrap merchant, most can be cleaned and would be usable. Make him an offer if you need a spare. He has some complete ones but will only part with for a pot of gold etc.
At present no spare cast iron heads available.



Weber inlets and alloy hubs are cast and the hubs machined ready for final finishing and anodising.
Alloy Front hubs

The hubs are made mainly for racing guys with the weight saving on the front suspension but as the original hubs are becoming harder to find in good condition this gives an alternative to replacing those wires with Minilites (less maintenance). Weight is 1.296kg compared with 3kg .





Steve Platers MGC is now in the shop.
 remarkable condition just a few battle scars, patina they say! Engine and box are out and will be overhauled or rebuilt. King pins to be rebushed and new bushes on the torsion bars.
