New project

Post by kiwicar »

Hello one and all
a few of you Know of this already but I may aswell come clean now, I have stopped building the Mclaren project, for many reasons but most related to the shear cost of building a road leagle kit car, it is being moved to the side of the garrage to be compleeted as a purely competion car when I retire.
To the new project
I am about to collect a chassis off Roy Wilding a week on Sunday, it is a 168 wheelbase slingshot dragster built for 7.5 second spec. It is going to have the SBC in it which I have built up for the Mclaren with an all forged bottom end, RHS 235cc ally heads, a 253/262 at .05" lift mechanical roller cam with a dry sump oiling system, pretty much all done. Megasquirt controlling the sparks, which I have, and mechanical injection (still to get)into a sheet metal tunnel ram inlet (which I have). I have a glide on the way from the states with a 2.03 first gear, which will hopefully arrive soon. Roy has fitted a 9" ford aftermarket axel case for me (which is new, I have still to get the gears, probably with 4.11 final ratio and 35 spline axels. I am aiming to have it ready for the track for the beginning of 2012 and to run like this for the first season, with the addition of 200 to 250 bhp of nitrous for the season after. This will be my first go at dag racing and I expect to scare myself silly, I intend compeeting in the wildbunch series and probably either ETII bracket racing or competition eliminator A/D class (I think but you try sorting out the classes, it is doing my head in!). As always I would welcome any input from you guys, as drag race cars are new to me and I think the best brains around post on here. To start with I would welcome any input on the above spec? Anyone on here know what spec tube do you recomend for the front axel on said slingshot with ford spindles and a torsion spring front suspension with leading links?
I shall post up some pictures of the new chassis when I pick it up and the build as it all goes together.
Best regards
Mike

Hi Tony
I will ask him on Sunday if I don't get an answer before then, I don't want to call him now as it takes up more of his time and I have taken up alot of that over the last few weeks. I was hoping if I got an answer before then, if I can I could start tommorow on this bit as I have some CDS tube in the garage.
Best regards
Mike

Hi Rich
I thought going for a slingshot was a good plan because I hate getting my knuckles skinned on body pannels when I am working on an engine and I wouldn't have to lean over anything to get at it. I am not sure that is the best basis for deciding on a project, but that is mine. So deep end it is should lead to some interesting times :?
Best regards
Mike

Get into the water and have a few mates trying to push back on the chassis while you snap the tranny into action to get the tyres to let go quickly :lol:

I have this image in my mind of a dragster crossing the line with two of the team standing on the weelie bars hanging on for dear life at 150 and the driver puzzled as to why his car was a bit slow off the line :?

Nice one Mike,

Front axle is normally at least 3mm wall thickness. You will be happy about the weight on the front end anyway. Make sure you build in plenty of caster, Around 18 to 20 degrees is normal for a slingshot. The wild bunch is a great place to start, I would imagine you will fit into PRO ET which is very competitive, you will need to be able to run within a few hundredths of your dial in to be competitive. As for comp eliminator, well!!!! To be competitive in A/D you will need to run 6's and nitrous is not allowed!!!! Just getting on the track in Wild Bunch and dialling the car in will be loads of fun, so worry about the rest later.

If you are going mechanical injection then run methanol, it is much easier to tune than petrol. Get the system flowed to have a good starting point and its much simpler than a carburettor. Flowing the system is without doubt the best money you will ever spend. Good luck, we intend running as many Wild Bunch meetings as possible next year so I will be over for a nosy. Just come and get us if you need a hand with anything, The guys are really friendly and you will get all the help you need in Wild Bunch if you just ask.

Alan
