Radical/Ground Breaking Builds ?

Post by nitro2 »

Anyone working on, or even contemplating, a radical or ground breaking or just way out there build ? Anything. Sorry.....getting tired of hearing about what cam to use in a 350 Chevy to run 11s lol, this is "Speed-Talk the home of racing's best and brightest".

Yup
i'm all for that too , even heavily modified rebuilds , like the ferrari thats here somewhere , or if anyone wants to share extreme development , even old stuff ,

Not radical or ground breaking but maybe a bit out the norm.
I will start first, just to get it rolling :) . At least its not a cam for a 350. :lol:
Not in full building stage yet, still gathering parts and scrounging everywhere on info etc, but in the works, chevy inline six 230/250.
Haven't decided which one as i still need to get pistons later , but currently building intake and nose piece to run 4-71 blower, still checking up on which carbs to use, i have a choice of 3, a qjet that is modified to boost ref the power piston. Or a single 48idf or maybe 2 40idf's.
Its my first blower build so checking all over where i can for info and getting ideas for the belt drive. Space is limited so i collected some various gilmer drive pulleys to use (those kits that do the normal v-belt drive on sbc). Biggest or widest belt i can get in about 1¹/²".
Its a slow build for me as i'm also completing 2 other builds (1xcar and 1x pickup) but normal finishing assembly etc. Small jobs but time consuming.

Hope it suits your criteria :D .

I think the days of people posting documented builds here are a thing of the past, I could say why I think that is but it would not change any thing.

Personally I questioned if I should even comment on this thread.

About as radical as I'm going to get is add a Derringer to my 19 L5P. Always wanted a 500hp truck to pull the 5th wheel. 8)

I think the issue is that the craft has split into two groups:

1. Budget constrained projects built from garage left-overs.
2. Late model performance cars that are so well optimized that an individual or the performance aftermarket can't afford the R&D to improve on the OEM parts unless they change the operating requirements. For this segment there isn't enough left on the table to chase after, let alone the emission's modification laws and warrantee.

I don't think there is a home for anything new in the market.
The nitro teams that I spent some effort to help could not afford to risk their tune to try even something they thought would work.

A lot of smart people working on new battery ideas but not particularly for performance cars.
A battery break-through will be a game-changer for lot's of projects.

I have moved on to electric powered vehicles for my regular job, but still design some castings for people in the aftermarket.

This might not qualify as radical or groundbreaking, but perhaps it might be interesting to some.

We have begun the engineering design process for a Porsche road race car; engine, suspension, custom ABS brakes,
aero, tires, gearing, and data logging.

The purpose is to optimize each performance area before construction, and then validate each aspect
with actual recorded data.

As such the data system is a bit overwhelming. Currently we plan over 150 data channels for the engine alone.
The aero, suspension, brake and tire sensors are another large mass of sensors.

And then, there is the data necessary to train the driver what to do to win every race.

While I cannot share specific information that the customer has paid a large fortune to obtain, I might be
able to discuss the type of information being collected and analyzed.

For example, the tires will have 16 infra-red temperature sensors reading across each tire, real time pressure
transmitters, and tire spring rate sensors. Vehicle aero data will use 24 pressure sensors, strategically
placed about the car. There are vibration sensors for suspension, drive line and engine.

We are having some difficulty asking the driver to accept a "pucker factor" sensor; perhaps that is because it
currently is only available in suppository form.

I'm doing something somewhat different. I'm trying to go low 11s but without a cam. Trying to see how quick I can go with a Gen 2 LT1 5.7L with a stock 160k mile bottom end, stock compression, stock cam, stock heads, and stock intake manifold in a '93 Camaro. The AC, PS, and alternator are deleted with a 16v battery, electric water pump, ATI small aluminum shell damper, 52mm throttle body, ram air from bumper, 1.7 rockers, thicker pushrods, 1-3/4" longtubes (and will be messing with collector extensions), Sunoco EXO2 fuel, Moroso 7qt oil pan with 5.5 qts in it, 0w-8 oil, 130-140*F staged temp, crankcase evac, 9" high STR 4000 stall in a TH350, 4.10 gear, 28x9 M/T PBRs, etc...

Haha a good cam will blow you away and be tame.

So what is? The only problem I see is the cam.
