Thread: Its Alive!!!!....well...almost.

Just thought Id share and update you guys on whats been going in with the build progress of "BiGRed"...my 1994 Mustang GT.

For those who dont know or have forgotten...this is a "street legal" drag car that I will be racing in a nationaly sactioned event over here in the states called NMRA (National Mustang Racers Assosiation)...

The engine is a "bored & stroked" 427cid smallblock that is purpose built to hold up to the two stages of nitrous that I plan to throw at it.
This combo is expected to make ~650 hp at the flywheel naturaly aspirated. We should be able to double that with the nitrous for a grand total of something between 1100-1300 hp. This should be more than enough to dominate the class that I plan to race in. We'll see soon enough.

Will be starting the engine for the first time this comming Saturday and will have the new custom fabricated rear axle assembly installed by Wednesday of nest week. Then its off the the chassis dyno to get the engine broke in and write a base tune for the ECU so we can start shaking down the chassis/suspension.

Hope to have a vid of the engine running by Sat night.

Here are some of the new pics.

thats going to be very sweet mate.

good luck in the races.

Phew!!!! Justin that looks sweet

Very nice Justin.

Sorry about that.....its fixed now.



Here is a pic of the custom fabricated axle housing I had built....hopefully this one wont bend and twist apart like the last one did.

Looks great!

Lets just hope with that much power the rear axle is fixed firmly in place so it doesn't suffer the same fate as the Camaro in the vid that was posted very recently on here!

Arghhhhhhh....

Was not able to start the engine yet due to some electrical bugs...but will have them sorted out soon.

Will update asap upon further progress.

?? no updates on this one I'm guessing?

Hello all. Sorry for the horribly long delay.

As for the car....progress has been great.

I managed to get through an entire racing season with no parts damage and learned a lot about nitrous and suspension tuning along the way.

The engine combo did not make the hp I was expecting due to the volumetric limits of the engine. It just would not ingest any more than a 250 hp shot of nitrous. Just as well...as anything over a 150 hp shot and the suspension was overwhelmed and no gains were netted due to loss of traction.
The engine made 498 rwhp on the engine alone...699 hp with a 150hp shot of nitrous, and 781 rwhp with a 250 hp shot of nitrous (150 hp on the first stage and another 100 hp on the second stage).
I believe the torque converter was letting go (slipping) around the 700rwhp mark and the engine just didn't have the volumetric efficiency I had planed on it having.
Still....I was happy with the results considering I was still utilizing the factory stock ECU, factory electronics, and stock geometry suspension (aka stock mounting points).

The car went a best of 9.91 @ 134 mph, with a 1.33 60'.

Here are some vids of the beast...

Some fun at a local track that's known for its lack of traction (not the case with a proper suspension setup)

As I stated above...the engine combo fell short of my hp goal. This was due to the volumetric limits of the heads I had. They flowed 315cfm (cubic feet per minuet) at 600" valve lift. I have since bought a bigger set of heads that flow 360cfm at 700" valve lift and am also switching from fuel injection to a single Holley Dominator carburetor and a direct port nitrous system and nitrous plate (second stage).

Here are the pics of my new heads and intake when I test fitted them on my short block in the car, with the new headers that have 2 1/8" primary tubing and 4" collectors. As can be seen in the pics....its pretty much a straight shot from the carburetor base to the backs of the intake valves.

I took this year off from racing so I could fund next years engine build. Hope to come out with a strong showing in the Spring of 2010.

Test fitment of new heads, headers, and intake manifold.

Picture of the exhaust ports of the new heads (yes...a golf ball will fit nicely inside the exhaust port) lol

Formal request that an Admin/Mod move this thread to the "Motorsport" section of the forum.

I apologize for the inconvenience. I don't know why I posted this in the "photo equipment" section.

Thanks in advance....,

Justin

Bloody hell...thats fast

Thats awesome! Quick question though... whats the smoke thats coming out of the bonnet vent on a couple of vids? Is it to do with cooling?

Purging the air out of the nitrous system plumbing.
