Engine Question
Hello i am new to the drag racing scene and have a few questions if anyone could help. I would like to build a street car to run mid 11s N/A. Was
wondering what hp output would i need to produce these times. Also what would the weight be roughly of a 1969/70 model bug after it has been modified
engine wise. Any help would be much appreciated. Also have been checking out aussie dubs such as dave butlers and rod richardsons and was just curious
as to whether what horsepower these are producing at the wheels. cheers

lets start with about 250hp, and correctly tweaked / setup chassis / gearbox.

It is hard to say what weight your bug would be because of all the
extras and such that you might want to add for strength and saftey.
But just for interest, my bug is currently 1775lbs (807kg),
and I think Rods was about 1750lbs (795kg) before his new roll cage.
Dave Becker's car was around 1850lbs (841kg) from memory
This includes the drivers, so I would guess yours to be around this unless it is a lightened drag car.
With my best speed of 118.2mph the engine was making just under 229hp and about 199 at the wheels.
With Rods best speed of 112 mph, I would guess it to have around 192 hp and 167 at the tyres.
This is on Dyno-Dynamics brand dynos in shoot-out mode,
and are 'corrected' figures.

Awsome thanks guys for your help. So do you think it would be possible for a normal nonlightened bug (1969/70) to get into the 11 second time bracket
with about 200 hp at the wheels?

I would love to hear some details of your car and its previous combinations.
As would other drag racing VW guys.
I could just ring Mike, but he would probably check with you first anyhow.
What did it make at the wheels,
and what other details like tranny and suspension does it have?
Any pics?(if pics are trouble, emailthem to me and I can post them).

Hello again. Well we did have a 2276cc with 44 idfs which was quite potent but we did not have the tranny hardware to give it a hard run. It was an
awsome engine to begin with but decided we wanted to go faster. So we went with this final combination. 2442cc with 51.5 IDAs ( 52s maybe), cb comp
eliminators 48x40, 88mm Bugpack flanged crank, 94mm AA performance pistons, FK89, Pauter Rockers. These are just a few specs from the top of my head.
We had the gear ratios changed with a 3.88. Not sure on the exact gear ratios. When on the dyno she produced 199.5 hp atw on pump gas and full exhaust
with more still to come. The car is fully registered and our goal was to have a street car to run 11s. Just to give it to alot of the japanese sports
cars. Narrowed front and shorter rear axles and all neccessary parts to push it hard. As yet we do not have any photos but will try get some soon.
Mike built our last motor and again with this one. Mike has done an unbelievable job and always thinks outside the square. Full credit to Mike and
staff we are very happy and cant wait to see what it runs.
Its great to see your race car and what can be achieved. Hope to see and meet u at a meeting some time.

Also Peter Page drove Rod's car to an 11.96 with less power than it has now.
I think mid to low elevens are quite achievable on slicks.
Look forward to meeting you also.

From memory I think he pulled 11.88 at Heathcote and had something like 215 at the wheels at our club dyno day a while back before the car was rebuilt
1954 Oval long term project going nowhere
1958 Beetle drag car project
1959 Beetle project I need to sell one day

11.88 @ 110mph on a 33 degree day, not the best temps for racing. It made 220hp on the treads.
The car was fairly stripped inside and no bumpers, no back seat, 3" weld wheels on the front and slicks made for a pretty light car.
Wish I got to go for a ride before it was turned into a classic race car.

Hey well my orange beast managed a 12.5 with muffler and et streets however top gear was a bit tall ( as we wanted this for street use). This will be
now changed to get the mph up and hopefully et down. This time was produced after 2nd pass ever! Was very fun night blowin the doors off most cars.
If Deans around i will let him let u guys know how he went.
