I'd say that with the amount of hp out of my TT it's probably impossible to get that much without a humongous camshaft and humongous everything else. 

John Vittone offered to pull a vlave cover and dial guage the valve lift, but I can do that at home.  There is almost nothing about the engine that I know.  Information I got was "It gains 200whp if you remove the airfilters you know"  When I run out of other projects I'll probably pull the engine down and see if there'll be a big advantage to replacing my JM heads with a set of ported GTSR heads and check the cam then.  Next couple months I'll pull the pan and check the rod bearings in the bottom end.  Yep, #3 and #4 at the very least.  I am also interested in whether the crankshaft has your modifications of a GTSR crank and what brand H beam rods are in it.  It'll give me an opportunity to double check that it has a swinging pickup and trap doors in the oil pan as well.

You must be running terrible air filters to loose 200rwhp through them lol.
The guy you bought the car from must not have been who built it if you didnt get any build info?

Even K&N air filters can't support 1500+whp of airflow without it being a major restriction.  I understand that when YOU instal 1 of my airfilters (they are 9" long x 5 or 6" wide) onto your Paxton it's going to losee you at least 50whp at 850whp ...  Mine also uses convoluted 3" mandrel bent tubing to get the air from the bottom of the car into the Turbos past the headers which at 26psi go cherry red after 30 seconds ...   There is a thread(s) on my car on Viper Alley and the filter restriction  was posted at zero loss (Must be at pump gas 10psi boost).

I bought the car from a big lawyer in Texas and the car was built by ART which has been providing me with "tidbits" of information on the build.  Todd has been helping me to convert the car to the Salt flats and offered free tuning ...  etc.

Their TT Viper coupe "Ballista" is the world's fastest Viper in the standing mile at 147mph(?).  I would presume that my engine/car is pretty much a copy of theirs, although they are running a standard 1800whp tune with perhaps as much as 2200whp on occaission?  I think that they would like to protect much of their build info because of propietary issues?

Oops, this is Joel's thread ...

I do think those 3 inch pipes are a restriction for sure.  Filters are not gonna help.  But turbo location is no better for the heat part either. 

On a second note got my striker diamond pistons today.
Custom cometic gaskets and custom full 360 grooved main bearings.

Now if I could only get my jesel lifters and rockers.

So how much are the slightly used Diamond pistons worth?

What is the problem with the rockers?  Are they custom or Gen 2/3 style?

You never said how your rod bearing were when You pulled it apart this time Joel ...

The diamonds are brand new from Drummond Racing. They had all the piston specs from Sal's car which is running the race heads. The pistons are very beef compared to my previous wiseco's
They are a very expensive piston at $2500. They did come with a special steel rings. In the past I was running moly rings , they had a thin chrome plating on them. Problem with these is I personally think they are a low boost option.  I wouldn't run them on anything boosted for me personally as a little too much heat ( detonation ) and the cook the coating off. This material flows through the oil system and you have bad results.
Now as for the bearings it's hard to comment with my previous statement not really giving them a fair chance.  What I can say is there was a big difference in discolouration. Before you could tell the bearing got hot. This year it looks like I simply had the moly material go through.

As for the lifters and rockers. Lifters are stock replacement jesels to go with the solid set up. I have no choice to run these with the big cam.
The rockers are a 1:7 gen 2 , but the strikers ask for custom stands.
Apparently they are ready to go from jesel but waiting on the vendor to pay for them. This has been a slow process.

Paolo received my mitech intake today. It's suppose to go out to me tomorrow.

So there was a problem with the rings before?  And the pistons from last year were Wisecos?  Sheesh.  Crank OK?

Sal's TT went 6 sec ... 

I'm wanting to see the new intake mods ...

The art record holder is a gen 4 ACR-X. DID 240.9MPH At 1800rwhp.
Why dont you run silicone tubes instead of aluminum? My snowmobile is 330hp on a 1 litre engine (that would be a 2600hp 8.0 litre in comparison) and we saw good gains going to silicone charge tubes and airfilter to turbo elbows. Something to consider.. I will dig up some dyno tests that were done on an 8.3 litre with different air filters and without an air filter. Not much difference in hp.

Even K&N air filters can't support 1500+whp of airflow without it being a major restriction.  I understand that when YOU instal 1 of my airfilters (they are 9" long x 5 or 6" wide) onto your Paxton it's going to losee you at least 50whp at 850whp ...  Mine also uses convoluted 3" mandrel bent tubing to get the air from the bottom of the car into the Turbos past the headers which at 26psi go cherry red after 30 seconds ...   There is a thread(s) on my car on Viper Alley and the filter restriction  was posted at zero loss (Must be at pump gas 10psi boost).

ART has 2 ACRXs ... well they did have when they quit running the 06 coupe Ballista (thought that was what Todd said).  There was a "other bad driver" accident that caused a serious crash with endo flips and one of the ART cars was tapped sideways causing their car to crash. Todd and his son decided that because of that they weren't gonna race that series anymore ...  But I saw the Ballista during the VOI 11 at Miller Motorsport track.  Talked to Todd and his partners there about that car and shot some pics ...  Pics back in 2010 (I think).  Here's the article ...  Tod said that he'd gone faster than 247mph and if that wasn't his record time I guess that was one of his testing runs.  The video shows the side windows - which the ACRX doesn't have because the side bars of the cage go through the inside of the doors. no spoilers, no canards, etc.
