Will be interesting to see what numbers this beast runs. If their other car is any indication. It will be an animal.. Are they still going 2 run their other car??

Yes, we will still be running the other car (4.6L with the 85mm turbo).

Next year will be run as a 2 car team which should be interesting as far as the work load goes.

Compared to the Red car The White car has 44 more cubic inches and will carry a 3 mm larger turbo, but it also has to weight 146 kg more.

Joey.

[Camper]

Thanks for the update Joey.

This is a little different.

Animals, cannot wait till see both of them back on track...

[Camper]

I think this Vette has gone into the 7.60s on radials? :D

The photo below shows how much aero plays a part when you're going this fast.

Drag Radial racer Joey Bridge is sorting out a car for his new teammate, Sonny Biggs, and while it’s smooth sailing for Tony Akins (in the foreground), it looks like Joey and company need to shore up the splitter a little bit. Unless, of course, the “unintentional off-road encounter” look is what they were going for…

Any updates with the blown animals State Side??

[BridgeRacing]

The white Mustang should be ready to go by the weekend to do some more testing.

The car has been down for the past 2 weeks while we were waiting on a Reid SFI Power Glide trans case.

We built the car using the oem trans case for the sake of weight but we are making more power than our Red 4.6L Mustang so she was distorting under pressure/boost.

Our next race is 'World Street Challenge' up at St. Louis Missouri May 16-18.

It should be a huge event as there will be all makes models..... Imports, Ford, Chevy, etc. It will be like mixing a NOPI event with a Domestic sanctioning body.

Best ET with the car so far on the BFG radials is 8.19 , best mph is 181.67.

The event in St. Louis you are allowed M/T Radials so we hope to get in the 7.70's possibly 7.60's, it will all depend on weather.

[Zannaa]

So good luck at the world street Challenge!

[BridgeRacing]

Holy Crap, we ended up winning Drag Radial at World Street Challenge.

For fun and to see what we could do on them we decided to run the 275 M/T Drag Radials instead of the 325's.

Qualified #2 with a 7.88 @ 183.

Ran in the 7.80's 4 straight passes with the best being in the finals where I ran a 7.84 @ 184 mph.
The half track (1/8 mile) was a 5.16 @ 145 mph.

Let me tell you those 275's were on the edge pretty much every part of the track.

It was $5000.00 to win and man it feels good to leave a race track ahead for once.

That's awesome Joey! :) Well done to Bridge Racing

Consistent 7s on 275 radials...WOW :eek:

Congrats Guys, Fantastic Effort..

[BridgeRacing]

Just another little update.

We just got back from Milan, Michigan running Drag Radial (NMRA Event).

In NMRA Drag Radial the max turbo size is an 88mm and you must run on 325/50/15 BFG Radials.

Missed a couple of qualify sessions while we where swapping transmissions.... again!

Qualified #2 with a 8.24.

Made it through to the Finals where we were up against the 2006 & 2007 Champ John Kolivas.

We took the win with a 8.17 to his 8.20.

12 hour drives usually suck but for the first time it was actually enjoyable :D

wow :shocked congratulations again and keep us update with that wonderful job guys!

[Spoolin_20B]

congrats on your win
one very nice car

[BridgeRacing]

After a runner-up at Chicago Route 66 our next event was Atco, New Jersey which we just got back from.

We ended up breaking the National record with an 8.020 @ 178.
We backed it up with a 8.024 @ 177.

She went 5.25 @ 142 mph with a 1.37 (60ft) on the 325 BFG Radials weighing 3400 lbs (1545 kg).

It started raining Sunday so we will have to wait and see when the rest of the event will be run. It sucks to be on a good roll at an event then have to wait a few weeks to run eliminations.

I like this one Joey :)

I read on your site that it's gone 7.71/184?!

Man that sticker on the bumper is no where near being straight, we put that on down in Florida during a wind storm...... Super windy with a bit of sand thrown in :D

A couple a weeks ago he went a 7.64 @ 187 mph up in Ohio.

We recently changed the car from a Turbonetics 94mm to the Precision 94mm and picked up a couple of mph.

With the class rules he can run a max turbo size of 94mm, small block ford and must run on a 28 x 10.5 (True 10.5) slick.

He is having a ball :)

Here is another shot of the car testing in Chicago:

We took the white 5.4L Mod Motor to the NMCA race this weekend at Memphis.

We are considering heading to Las Vegas in November for the PSCA race so we put the little 275/60/15 Radials on the car. We also put the 94mm turbo on, no wheelie bars and weighed 3200 lbs (1455 kg).

Best pass of the weekend was a 7.73 @ 185.95 mph :)
On that hit she went 5.08 @ 148.77 mph at half track.... 1.35 (60ft).

Also went a 7.78 and a 7.76. Sure is a fun little tyre.

The 94mm turbo topped out at 26 lbs of boost so we are thinking we should get about 30 lbs of boost out of her if we go with a 98 mm.

[2rismo]

What does the red car weigh?

[fullboost]

7.7s on 275s! :eek: That's mad, well done Joey.

[SSN8R]

thats ace man
well done on the time, and the build altogether. very impressive.

[BridgeRacing]

What does the red car weigh?

3100 lbs (1410 kg) with driver.

Thanks Guys.

If I can organize everything right I will have to attempt to come down your way. I get back to Australia (Brisbane) at the end of December and will be there for about 3 weeks.


If your going to be at the Summernats might see you there :)

[2rismo]

3100lbs! Damn! That's honkin'!

[oke020]

The 94mm turbo topped out at 26 lbs of boost so we are thinking we should get about 30 lbs of boost out of her if we go with a 98 mm.

so what your saying is the engine flows so much that with the turbo running un wastegated flat out its only able to go 26psi above atmo, thats cool :)

[BridgeRacing]

so what your saying is the engine flows so much that with the turbo running un wastegated flat out its only able to go 26psi above atmo, thats cool :)


We control the wastegate with CO2. We have a single 60mm wastegate with only a 2 lbs spring in it to control flutter.

Through the boost controller I input how much CO2 I want on top of the wastegate.

Once your boost pressure in the intake flat lines the more CO2 you put on top of the wastegate does not increase the boost pressure in the intake it only increases back pressure.

Now you do have to have some back pressure to keep the turbo in it's 'sweet spot', all combo's are different so it's trial and error.

So if 26 psi of CO2 on top of the wastegate makes the same intake pressure as 36 psi of CO2 on the wastegate all you have done is increase back pressure.

The wastegate is working it's ass off all the way down the track trying to keep the exhaust system (between engine and turbo) a consistent pressure.

Enough rambling :)

[oke020]

Ah yes ok thanks for the info, never even thought of doing it that way, makes sense that standalone pressure source is a perfect way of knowing whats going on in the exhaust manifold :) could you make the smaller turbo work harder by increasing the turbine housing size and decrease backpressure? acutally you probably already run the biggest turbine housing, not used to large cube engines and all that nice airflow.

The reason we use the CO2 method is to be able to hold the back pressure at a certain level.
All the way down the track the waste gate is never locked shut (seated), it is opening & closing constantly trying to maintain the exact back pressure we are after.


This way we get to run a smaller exhaust A/R with out the negative effects of huge back pressure.

These things are making so much power that the torque converter's are getting tighter and tighter.
The problem with that is with a Power glide/Torque Converter they are a bitch to spool.

By running a smaller exhaust A/R and just relieving the back pressure through the waste gate she spools nice and quick but the system thinks your running a large exhaust A/R.

If the pressure in the intake is the same 'Say 26 psi' -- 30 psi of back pressure is the same whether your running a 1.0 Exhaust A/R or a 1.32 A/R.

If you have a Turbo maxed out (intake pressure) with a small exhaust A/R and you go to a larger exhaust A/R you haven't made the turbo make any more boost (compressor side) you have just freed up the exhaust side (more efficient).

By running CO2 on the waste gate with a light spring you can manipulate the waste gate to relieve exhaust pressure to make the system think you put a larger exhaust A/R on.

Also, in the Drag Radial classes you tend to have to peddle the car once in a while. With the smaller exhaust A/R you can recover a lot quicker (less lag).

We are currently building a Drag Radial car that is a large ci small block Ford (427 ci), We will be running a 114 mm Billet Wheel Turbo on it.

With such a large wheel and being a billet wheel (heavier) on a small block engine we need to run a smaller exhaust A/R so it's not a bitch on the startline with a Pro-Tree.

With an engine this size we will be running 2 x 60mm waste gates to try and control the exhaust side of things.

The 114mm Turbo is Huge :) :

Thanks for the info Joey, that makes a ot of sense re the back pressure.

Is there a turbo size limit in the DR classes?

[BridgeRacing]

In NMRA you are allowed a max of 88mm. It has to be a one piece compressor housing so your not allowed a 98mm with an 88mm sleeve inserted, etc.

Now Outlaw Drag Radial pretty much anything goes....... Single 114mm's or Twin 88mm's.
Outlaw Drag Radial is starting to turn in to Outlaw 10.5 on Radials.
