I think drag cars lang, see the way the rear suspension is set on the chopped top. But im not sure.

It'd be cool if they can be made for track ;D

ASCAL:  the guys I mentioned are all around Manila.  The other guy in Subic.   Just PM me which one you want to talk to.   Or, better, if you make to BRC for Oct 1 or 2, we can talk to them there

are those race cars or are they intended to be driven on the road?

follow up question... those are DRAG cars right?  not intended for circuit use...?

Those are strictly for drag, offroad use only. Nope, not for circuit.

I HAD plans of building an Ultima GTR but ive put it off for an off the shelf car (Z06) but the idea of making one still lingers in my head.
there are a lot of advantages of making a tube frame car:
 a. simpler compared to a space frame
 b. more rigid than a spaceframe, depending on design, quality of materials and workmanship.
 c. you decide what engine, steering and drivetrain to use.
 You guys have it easy, you guys dont have to worry about government regualations on safety and emissions!!

Isn't a tubular chassis a spaceframe?  Wondering what you mean by spaceframe.

aaagh...sorry about that. i meant a unibody.
spaceframe is still different from tube frame.

Haha, siguro me-crush ka kay Pebbles.  That's funny!  ;D

I saw one being built at Matonetics.   Goal was @650kgs.  All-motor daw.   That's amazing how they were building it by hand, using a plumb bob with some string and a steel ruler.   Pretty simple, I guess but definitely a very specialized drag car only.   Should be good for 10seconds with either a B20 or H22A   ;)

A bit OT:

Most racecars in the past used to have tubular spaceframes as their chassis.  There's the famous Maserati birdcage of the 50's for example.

Colin Chapman of Lotus pioneered the use of the monocoque (unibody) using two rectangular section frames made from aluminum honeycomb sandwich running the length of the car, a stressed floor, and bulkheads during the late 60's.

The art of the race monocoque remained the same until John Barnard of Mclaren pioneered the use of carbon fiber monocoques in the early eighties.  This has remained the standard to this day.

Most passenger cars today use steel monocoques as their chassis (stressed floor, stressed roof, with 2 bulkheads) replacing the old ladder chassis still used by trucks and heavy vehicles.  Some sportscars use aluminum monocoques.

I guess the above post was triggered by the picture of the 2 hatchbacks with floors sheared off and tube frames welded in. Basically shearing off the floor kills chassis rigidity.  What remains of the original unibody chassis (sides, roof, pillars, bulkheads?) then becomes basically an unstressed body, with the new tube frame taking over chassis duties.  

If they did the job to lighten the car (for drag racing), I wonder if the weight saved is significant enough to make the effort worth it.  Seems like a lot of work.

No offense meant to the builders.  Just raising a point of discussion.    :)

passenger car monocoque (sounds too european for my tongue)  design is totally different from race car one. hence, the need for a rollcage that doubles as a tube frame backbone.
the pics above seem to illustrate a design that fulfills its intended use, drag racing.
to remove a part and replace it with something that is more rigid certainly make sense. after all, what production based race car doesnt need a rollcage?  
colin chapman designed his cars to last one race. he made them light though. its a good example of designing to meet ones goals.

when i square a car to make sure that suspension pickup points and axles are parallel and true, i use plumb bobs, straight edges and strings. novel and easy way to do it.

I don't think this is new.  I think this has already been proven in the US.   i think the pinoys here are just doing it much cheaper than how they do it in the US.   Let's see if its effective.   The problem over here may not be the cars themselves but the track.   The track they use at macapagal has a horrible surface.   It cannot give the cars a good launch because the surface is dusty and not built to handle powerful drag cars (its asphalt lang I think).   The surface at BRC is ok naman but the track is only 800 meters long.   Delikado if you're running faster than 12 seconds.  

We may have the talent and the cars but the Philippines does not have a decent drag racing track
