Its Back!!!! TWINZZZZZZZZZZZ!!!!!!!

I like the thinking. So how much trq is it producing? Are we talking mountin motor territory?

 

[JDSfastGN]

damn thats pretty impressive... it did seem to lag a bit, but i don't know how much that had to do with the driver easing into it or not. Seems like a cool setup.

I just watched the video and would have to agree. It seemed quite a bit laggy. I know the tranny is acting up but it didn't seem to build boost very fast on the street.

Then again it really hasn't been tuned either so maybe after it's tuned it will come on quicker.

 

[GNandGS]

I thought they were controlling that for traction concerns?

Watched the video, and was wondering where is the maf located? The turbos did not have any intake pipes.

They are running a MAFless system XFI on the car I think.
You can also do this with a Speed Density chip or MAF Pro.

Its going to have to be taken apart. We didnt build it, we dont know whats in it, and we are not sure what would cause the problem. Old Age?
We have something we can put in it for the TB.com meet up :wink:

I know where it came from and I am going to put it up someone's azz if it ain't right... It is brand new and I know where it came from! Remember having to get instructions on the transbrake?

 

[GNVYUS 1]

Wow, considering the stock turbos a 49.5 compressor wheel that thing made some sick power on low timing. Two TA49s at 58mm each would need a TA block for sure even at moderate boost levels.

It looks like you customized the lower intercooler pipe to work with any FMIC, correct? Good idea if you guys plan on cranking these out.

I might have missed it but what fuel pump, injectors and DC%?

 

[TURBOPOWERED68]

Awesome stuff.

 

[gbodygmachine]

Awesome, we need more road footage/burnouts:biggrin:

I'll work on that.

We never got a really good torque reading. It had some spikes in it. Looked like a solid 520 ft lbs.

I was taking it easy. No need for spinning on the street.

Yes, it is a custom piece

I will find out what fuel pumps, 60lb injectors at mid 80% DC

Awesome stuff.

Thanks

I think the best setup for this kit would be a pair of 44s with small 4 bolt exhaust housings. Like T3s with a .5x AR. It would make way more power than you could ever use on a stock block but should spool pretty well with the small housings.

Wow I hate you Jay.
Now you got me thinking!
Quick question, why the low numbers on the 71GTQ?

Our dyno just doesnt put out huge numbers. At 509 or whatever it made, the car ran 10.30s without really leaning on it. This is a full weight car with nothing out of it.

Which according to my calculator should be right for 3600# car...

It is often a joke how some shops crank up their dyno #'s only to have the cars then perform poorly on the track... I am not talking about buick guys so put the rocks down

How much do you think it tips the scales at with the guy who drove it on the 10.30 pass? Was that pass at the made with the same 28psi and timing as it was on the dyno?

I dunno.. Im purely guessing but probably 3600#s. Its still got AC and is all steel. The only thing thats been removed is the factory moonroof. The previous owner removed it and put Lexan in it.

The tune is EXACTLY the same as it was with the GTQ71. We didnt touch anything so yea, all the timing, etc is the same.

Very impressive work guys.

Big power with common parts. To take a car and improve on tuned 70 turbo numbers, untuned, and have the potential for more power is awesome.

All you guys sweating the details.... well that's just part of the process. Sounds like these guys were just testing an idea to see if it's worth it. I know I've "southern engineered" some stuff just to see if it's worth doing. I bet that details and packaging gets addressed as this progresses.

Give it hell guys. I bet you can hit those peak HP numbers with more conservative numbers once it's tuned.

Let us know how it behaves on the road. And with some tire on it.

We're not going to lean on it any more. I think that would be dumb with an engine with stock rods in it. I know based on how our dyno numbers translate to track times that we've long passed the safety level of stock rods with this setup.

We do have another transmission we can stick in the car. As soon as we get some time to do so, we'll get some more driving footage.

I agree. But there is obviously the potential, it just depends on how much your bottom end is built to handle.

Yeah, sounds like you guys have a stingy dyno but like you said, you know how it relates to track times.
It's still 100+ what people thought it would do on page 1.
