Superstock engine trial (Read 32,405 times)

[nzf2stocks.]

Cheers for that. So you still have to find a carb, dizzy, flywheel? I'm assuming the harmonic balancer would be included with the crank. Still, good value with the forged crank, alloy heads etc. Would make a good base for a saloon motor

True, but its not rocket science, anyone that can fix a lawnmower can do it, so long as you remember to clean and oil everything before you put it back together you cant go wrong. (oh, and the torque settings of course)

Sorry for this question if it is stupid. I am very mechanically challenged but I would have thought most engines would rev well more than 6 thou.

If this is the case they shouldn't do engines as I thort, done properly, 6 thou was not to stressful for an engine.

[Stevo]

I would hope, if the engine goes through the trial process and is successful and becomes accepted as a legitimate engine option, that they will then look at a similar package to run a Ford, cos I know some who would cut off their left testicle before they would run a Chev. There are similar sealed engine packages available in the US for the Ford option.

Wonder if they're doing this for fear of losing guys to the new F2 class.

More likely to be a cheaper alternative than stockcars ;D

[pallmall]

It is a trial proposed by an individual and accepted by the SNZ Board.
The reason behind the trial proposal is to provide an affordable alternative engine for the Superstock class to help keep the class alive for the future. It may also encourage guys to step up from stockcars. This engine was chosen as the hp is about equal to the average current superstock engine, give or take a few hp depending on dollars spent.

Not sure how it could damage the F2 class as it this stage F2s are taking far too long to get going, and they are intended for a different end of the market anyway.

I know Brendan will post about the engine and his proposal in good time.

[nzf2stocks.]

Actually, my comment made in jest may not be too far from the mark. A bit like the sprintcar/ modified debate, having an affordable engine in a superstock may tempt a few more stockcar drivers to upgrade. This may mean that a superstock will be cheaper to build and maintain than a stockcar; eg diffs, what is the price difference between a quickchange and a 9" with spool and floating axles?

If these engines prove competitive and reliable, and I cant see any reason that they shouldn't, it'd be cheaper to upgrade your stockcar than replace that CSL that went pop.

[salooncar]

All we need now is to drag the saloon class back to using the same control engine as the superstocks and that'll be a second class without the ever increasing engine costs (and better economy of scale for importing the engines).

[nzf2stocks.]

Good point. Modifieds as well?

It brings up the question why do so many Superstock (and Stockcar) drivers pay thousands for engine builders

I'm pretty sure a 9inch is more expensive to setup than a quickchange is.. got a couple mates running 9 inches, and my quickchange was cheaper....

Grunter. Who the hell do you think you are to insinuate we don't have the right to be out there with the bigger spenders?
I and plenty of others spend what we can afford and would rather race a superstock than a standard. My car may not be high spec or high horsepower but over its time its been pretty reliable and Im sure the bumper hasnt bent for no reason. Infact it has even been used to teams race with a very budget motor.
If you look carefully you will find there are plenty in the standard stock class spending more than 10k and still not winning. I have nothing but admiraton for anyone that gets out there, no matter what they drive, spend or earn.
I spose if you have the millions that you must obviously have please share it round so the rest of us poor guys can get to the front. Actually NA, Id rather be a nuisance than wait for your expensive motor to explode!!
P.S. Im putting a stock standard Toyota in right now just to annoy you lol.
Jeff See

Too slow jeff, i'm running a stock ford6 in my superstock straight out of a road car with 30,000k on the clock. i may not be fast like you ,but i'm out there doing it. And on a wet track i can hold my own for a couple laps as you've seen.......Oh and i think the motor only cost $450.

[MadMarty13B]

and probably faster than my 30k Holden that blows up all the time lol

[penman]

The positive comments posted in this thread (well, all except for Grunter) indicate just what a great step this is for the class.
Fantastic to see someone like Brendon thinking outside the square and SNZ having an open enough mind to accept this as a trial.

Also, big ups to Grunter for making everyone else on here look SO much more intelligent than they did before he posted....

[kruga]

Hi, now I dont disagree with this engine for a trial but lets look at the other options.
There are lots of other engines out there that could be utilised.
Why not look at a size limit of say 5 ltr.
There are plenty of motors out there that would suit.
People could run stock toyota, nissan, holden and ford, even chrysler.
They could use the injected ford and holden V8 engines with carburettor manifolds fitted.
Also this would reduce the need for the nissan motors and others to be de-stroked.
There could be control intakes for these jap motors, along the lines of the restrictor plate type of deal but not as "restricted".
Maybe a engine rev limit still in place, 7500 would be enough.
Rear drive quickchange gear set restiction.
Engines could be restricted internally to only have standard valve lift, maximum that that manufacturer had done for that particular engine.
There are obviously other issues that would arise from this such as proper control/policing of the engines but it may be a start.

If you run a particular size engine, say nissan 4.5, you should be allowed to run to 7500, have headers etc of course but maybe limited to 8.42 diff gears only, only be allowed the maximum valve lift that that engine came out with.

Or the other option would be injected V8s, all of the above included.
Control computers, likewise engine internal restrictions, rev limits, final drive gearing limits.
Just as the stockcar guys are doing we need to be looking to the future and what is in the wrecking yards.
This sport needs to be one that is entertaining and affordable.

Obviously this would give some of the engine builders a hernia too but it is still an option.

[4zfed]

Nobody answered my original question?
What horsepower are the top Stockcars in NZ not Superstocks?
My point being that if Superstocks end up with a motor costing $10k they will be considerably cheaper than what some stockcar guys are spending on their motors

[The Observer]

If
a) the engine is allready here
b) mARTYS SUPERstock has been dumped in favour of 77p
c) and 77p has blown up the old motor

does this mean the 77p and trial motor will be at the biggest superstock meeting of the year - Teams champs - for a show and tell and race??

Now that would generate some interest. and be a great indication of how it would go - especially with a proven car/driver combination who will ge tthe most out of the motor (no offence Marty)

Why bother when you can get a CSL or Hartley engine for $30k thats already proven.

If people can't afford that, maybe they should try or stay in stockcars and leave the superstocks alone.

30k, cant believe that! I heard csl cams will do you a ministock motor for 6k and thats you suppling the motor!!! Also so heard thats these holden motors from Hartley's for a stockcar are 30k! If it cost you 30k for a new super motor then why do you have to pay 60k 70k for a super that you may win in?

I hope these new motors do come in. Ive wanted to buy a stocky for a long time now but haven't because of the cost!! So i enjoy watching but wish i was out there!!!

have u rung csl to see what you can get for 30k ull be suprised

Hey nzf2stocks , I have a good chassis to throw your Toyota in.
