It was recommended that I go with a 10:1 minimum with meth for a street/track car. Motors not built yet but it's next on the list.

I'm going to run a 9:3 compression but I'm going to be in the higher hp numbers so I will be relying on boost for most of the power.

11-1 for me and I run a Maggie....With our record holding GTO street car were at 10.4-1 runs 8.70s at 4000lbs... It uses a F1R at 24lbs and runs 93 0n the street...The old school guys like low cr,back when we used carbs it was a must but with todays pcm and fuel injection and a good tuner CR is your friend...That's my opion and its worked great for us,im actually nugeing at Farrad to up the CR on there record holding 5th gen ...

Racing we bump the boost to 25 lbs and run C16 race fuel... in the tank and to mix with the nitrous...With the 429 CI, this makes for a hell of a lot more power....
Unless you have HUGEEE turbos I think your 12psi 900rwhp estimate might be a little too optimistic?

True

You decide... Here's a few pics of the turbos and the intercooler... I've included pics of my old turbos for a side by side comparison... Note the size of the intercooler in relationship to the frame horns... In addition to the 5 inch thickness, We had to clearance the core support to fit it in... We were over 800 rwhp with the old turbos and the bad inefficiency due to the turbos overspinning to make the boost... They were fine for a 376 CI engine, but much too small for a 429 CI engine... We mount these on custom hand made turbo manifolds... and those are 3.5 inch down pipes... That's our fabricator in the pic from the front looking at the turbos... He is a clown... but a damn fine fabricator and welder...

New turbos... X2

PTE's PT7675 Turbocharger features the following:
• Exclusive CEA® (Competition Engineered Aerodynamics) compressor wheel machined from a 2618-aluminum forging
• Higher efficiency and faster transient response for maximum power and performance
• 76mm inducer compressor wheel
• Compressor cover options:
- "H" compressor cover 4.0" inlet/3.00" outlet
- "Ported H" compressor cover 4.0" inlet/3.00" outlet
• 75mm, 84 trim turbine wheel
• Turbine housing options:
- T4 Tangential .96 A/R with 3 5/8" V-Band discharge
• Air-cooled, dual ceramic ball-bearing center housing rotating assembly (CHRA)

Thi is v6 or v7 of this car and this build... We find the weak links by breaking something and fix it then press on...

ahh, Bull needs to give me a swift kick in the rear..... I told him several days (week) ago that I would find out what I could about the characteristics of my old turbos... and I forgot... ADD kicking in...

I sent Corey an Email so I wouldn't forget again... We'll get the info to him...
