Lingenfelter twin turbo, LS1427 S-15 4x4 truck - March CHP

Just got the new Chevy High Performance. There's a S-15 Sonoma pickup with a twin turbo LS1 427 in it. 700+hp at obly 5psi, 900+hp capability. Cool. They say it pulls 1.4g's peak, while accelerating, maintaining 1+g's up to 40mph. Who says turbo's don't make off the line torque?

Lingenfelter is predicting 9's once they get the tranny built fot it, while still getting 18 mpg, street driven with A/C.

Technology has changed everything. 20 years ago, these vehicles simply would not be possible on the street. That's why it's so fun to push the envelope. 10 years from now, there will be street cars running in the 8's AND able to handle. I truly believe it & hope to be one of the first to get there...

while turbo lag is a problem, as long as you are able to load the turbos at the line and leave with boost, the car will launch plenty hard. keeping the bottom end fuel curve a bit lean, retarding the spark, and having slick equipment like ball bearing turbos and the right convertor really help too.

you guys have really built some extreme vettes. LOVE EM :yesnod:

a racer trick with turbos is to inject gasoline into the exhaust before the turbo to get and keep heat in the turbo. exhaust heat turns the turbo not exhaust pressure. this has been outlawed in some racing assoc. because one equipted like this wrecked in a race and the fuel pump to the exhaust fuel did not shut off and a big fire started and they could not get it out because it was being fueled by the gasoline. some over seas turbo cars have this feature as standard equiptmnt. :chevy

What the turbo ricer cars use to get instant boost is a little 75 hp NO2 shot. The neighbors kid has a Mits' VR4 twin turbo. He has bigger than stock turbos and he told me to cure spool up time was a shot of laughing gas with a 6 lbs of boost NO2 shut off.
