Viper Parts, numbers, bulbs, specs and info / Re: GTS power steering pump

This pump comes in many domestic Chryslers, Caddilacs, GMs, etc.  Some have different Resevoirs and some use a different pressure valve.  Most pumps come bare pumps

BBB/VISION-OE7330111 (#6240, 6243) remanufactured, with no reservoir.

Normal way to remove bushings and bearings is using grease.  I tried that on my Roe during a clutch change and it didn't work.  This would work better because bread's viscosity is less LOL

I dropped the pan on a 97 GTS to check rod bearings and install a trap door oil pan from Roe Racing before porting the heads and installing a Roe Racing 710 camshaft, rockers, springs etc.  ALL rod bearings were damaged but the main bearings were good.  I changed the rod bearings, trimmed the windage tray and installed the trap door pan kit.  Tuning was an issue and this car went to Dan Cragin's shop since local Portland shops couldn't get the SCT tune correct but Dan did.  He also requires checking the rod bearings to work on car and he found that the new bearings were prefect.  He went over the car found a computer feedback problem and sent me an email that I'd done a good job.  That car is awesome now and 550whp/570wtq and a great driver even with the big camshaft. 
     I recently bought a 1998 Hennessey GTS with SVS TT system (875whp/987wtq) and only 900mi on a new build (rods, pistons, cam, jesels, GG heads etc).  When I drove the car it took several minutes for the oil pressure to com up over 20psi!  After a couple miles the oil pressure came to 47psi.  Weird but it seemed ok once it warmed up.  I drove the car 3.600mi to washington at end of January where I loaded it into my trailer and finished the trip to the "Great White North" protected from the ice and snow.  Low oil pressure on start up in the cold again.  Once inside the shop I put the car on blocks and dropped the oil pan.  Rod bearings were all junk.  I dropped 5 and replaced 3 but I did have to polish 2 crank journals.  I trimmed the windage tray to cream puff engine style with tin snips.  The rod bearings were standard so it hadn't had a bearings failure and I had no idea what caused all the rod bearings to fail.  Perhaps the 15/50 racing oil???  The oil filter I removed was a proper Viper filter from Mopar.  I worried and then called Kevin at Exotic Engines and ordered an external oil pump and wet sump system. 
How-to section / Re: SRT Style Diffuser blades made for a Gen 2

For the new Viper I bought a new set of 6 powder coated Diffuser Blades from KngSnk (John Rodriguez-Hardy). Diffuser blades come on all modern supercars and many newer junkers as well. The diffusers lower drag and add a little down force by straightening the "Caotic Airflow" coming from under the car.  Straight air flows faster than jumbled air.

On my Sapphire GTS I drilled and tapped 1/8" aluminium straps. I drilled an extra front hole in the middle and moved the inside blades to the edge of the frame. The 1998 GTS is different so I installed the blades the way most are located using 3 of the bumper attachment bolts behind the rear wheelwells and I drilled and installed RivNuts into support straps that go inside the rear bumper and hold the rear of the blades steady. Here is a picture of the blades attached at the front and the inner support strap holding the rear of the blades. Just need to drill the 3 holes through the bumper and move the support strap inside the bumper. Tighten all bolts and installation will be complete.
How-to section / Re: Tire and Wheel Weights and Fitment for Vipers
« Last post by RTTTTed on January 20, 2018, 01:02:30 AM »
Recently I bought a 98 Hennessey Venom Viper.  It came with 20" wheels and tires.  The fronts measure 25" tall and the rears measure 26" tall.
I currently have 3 ongoing Vipers.  2001 Roe supercharged GTS.  ported heads and a 720whp build using dual 70mm Accufab racing TBs.  2. 1999 TT Viper GTS with 1500whp stock Gen 2 modified intake and dual 70mm Accufab TBs.  3.  1998 TT 1000whp built engine using stock Gen 2 intake and dual 70mm Accufab racing TBs.  According to various ratings my airflow rating should be about 1400cfm.  Thinking of upgrading the 1000whp TT with sheet metal intake and Oval blade Accufab TB (1696dfm).  Would like the 1800 cfm oval TB for the big power TT Viper though.

I copied this info from Accufab website to help people (and me) choose Throttle bodies for their builds; 

CFM Air Flow

What is CFM? The air flowing through a product is measured in Cubic Feet per Minute, CFM.  It's important to flow test a performance throttle body and find the CFM rating.  A 75mm Brand A throttle body, may not equal the performance of a 75mm Accufab throttle body.

This airflow analysis is important because, basically, an engine is an air pump.  Based on the size of the engine and how fast it will be spinning, it will pump out a certain amount of air. Of course, there are many variables to CFM requirements, such as cylinder head flow capabilities, intake and exhaust manifold flow capabilities, etc... but the basic engine block will pump a certain amount of air over a specified period of time, measured in CFM.  An Accufab throttle body is designed to outflow the stock throttle body, hence, providing more air to the engine for it to utilize accordingly.

Best I could get with my TT GTS set at about 950whp and smoking R888s through 3rd was 10.4@ 149mph. This year the machine shop I paid to cut me an input shaft to bolt a Lenco and Gear Vendor to my dual disc clutch Never got it done and I asked (and received) my money back.  So this becomes the second winter project.

Joel Fortin got his 98 TT GTS running and with problems he ran 8.7@168mph.
