9 sec run with a NA engine

[sven]

Hi Guys,

As the most from you know I'm trying to do a 9 sec. run with a NA engine, this weekend we achieved a 10.385 @ SCC, does anybody know if this is already been done in the past and with witch cars and engine.
If you know my car and have some ideas that can help me, I'll be glad to hear it.


Thx.
Sven.

[bang]

almost all prostock cars in us run 9 with n/a engines, roger crawford rund 9 in his superstreet ghia.

dont know if any in europe runs 9 with an n/a you, jussi, and kemp is on the way..

[Roman]

The only one I know that has a license plate and has been driven on the street was Mark Reilleys (Ex Dean Lowrys Pro Stock) with a ARPM 3 liter engine.
I know JPM was very close a lot of years ago with his pro stock (sold to Norway I think). He made a 10.02 or so as best and I think that is the fastest ever in Sweden.

Good luck - aiming for the sky is the way to go!

I still have my race car, one day I'll start to chase you.

Bus engines do not count 

Sven , what is the weight of your car ?

My Unlimited Street car ran 10.30 @ 133mph, street driven 2276cc. It made 180 hp on moter and 340 hp on nitrous on Heads Up dyno.

Hi Udo,

Sven's car is 640Kg now,he went on a diet this winter as he is also doing some cycle-racing  So i would guess he's around 710Kg all in...
Maybe Sven will confirm this...

Regards Steve.

If nitrous counts, then Bernard Newbury in Stitch Up is close - 10.001 @ 134mph I believe. Big Jaycee motor with a small-ish squirt of gas.

[BeetleBug]

Nitrous is supercharging and Svens car does not use nitrous.

GO GO GO Sven!

[Jesus]

Dave Dinning has run a 10.39 @ 129mph,

He is aiming for a NA 9 sec pass too!

Who else?

[marcus ösd]

maybe andreas åberg in the "herbie" i think his done 7.1 in the 201m so far with his "small engine" and theres alot of potential there. And wht about thomas kemp?

[Mags]

Marcus, Andreas Åberg have pro stock Chassi from Chassishop,
Sven,Thomas,Jussi and Dave have floorpan car

That's it . If you put a Ron Lummus chrom molly chassis under Svens car he will go 9's ....
640 kg is too heavy

Udo

[marcus ösd]

sorry i just thought it was a nine second na car in europe that was the topic.

[Roman]

Udo

I think it is possible anyway. Just add more power!

The super Street cars has smaller engines and about the same weight.
Super street regulations: 10.75 lbs per cui, minimum 1500 lbs including driver.

2789 cc= 170 cui, 710 kilos is 1565 lbs -> 9.2 lbs per cui.
If a super streeet can do a 9...

[sven]

Hi guys,

Total weight include myself is 710kg and this will  not change because i will not put any polyester or carbon parts on my car and the floorpan also stay.
I guess the only solution is find some extra pony's

What about bigger carburaters, currently i have 58 bergs but we have max. power with only 185 mainjets, maybe when we can more air into the engine we can use bigger main jets ....?
I do have to mention that we totaly have forgotten the venturis in the carbuarters they are only 48mm and the inlet valve's are 50.5mm, maybe I can start to make the   venturis bigger.

[Roman]

The jet size is depending on the vacuum signal from the engine.
It does not have much to do with the power.

I had 48 mm vents in my 58 mm Terminators with the same intake valve, but I never experimented with anything else.
I would go for a dyno session and experiment with different lengths on the intake and the exhaust and also vent size as you mention.

May the force be with you!

[ugly duckling]

i wish you good luck on your quest sven.  UD  .

My pro stock runs in the 9's with a 2442 engine NA

A way to get more pony's is to reduce spring pressure... in other words get a Raptor cam from JPM.

do you get free sticker from JPM? 

nah it makes sense what you say.

GO, GO, GO Sven.  don't forget it is a 'heavy latemodel' as well 

[JS]

My car improved from 12,65 to 12,17 from a change to JPM´s cam. And there is more in the car with a 1,7 60 foot. Before the 12,65 last year I had a proper dyno sessong, but not now.
Sven, call Johannes, I´m sure there is more HP to be found!

And NO, I don´t get a free JPM sticker either!!!

My early 59 is 75 kilos heavier... It made a 10 with a flat cam and street tires!

Dude, that is exactlly what he was saying: with a flat cam you need less spring....Its so simple, yeeezz! 

[BeetleBug]

Sven,

According to my calculations you will need 310 rear wheel HP to manage a 9.998 sec run - 132 mph when you car weigh in at 710kg - 1565 lbs.

Best rgs

Edit: I realize that my calculations are wrong. Your car is lighter than the weight I used. Good for you.

290 hp at the rear wheels should push you over the line in 9.920 secs.   

[Roman]

290 hp at the rear wheels should push you over the line in 9.920 secs.   

That means someting like 320 in the engine. With 2789 cc you need 114 hp/liter. Not easy, but is possible.

I know At the moment we have a bit more than 102hp/l. After Das Drag Day I will change some things and we'll try and hunt for that 9 second pass!

Hi Dominick

I have seen in Hot VW's from 2000 that Perkins did a super street record of 10,14 !! I think it was Dave and may be you know what car it was ? Nearly the same times that Roger does now in the same class

That is the car now owned by Jack @ Jay Cee Ent. and driven by his son Zack, and the Dave Perkins is not the same person that helps me, there is two of them.

[Udo]

Ok thanks . 10,14 was very fast at that time ...
