326 whp dynojet pics inside

WHP VS RPM POWER BAND IS SICK.ITS ALWAYS OVER 300 WHP WHEN DRAG RACING.



WHP VS SPEED


WHP VS SPEED WITH CONDITION VALUES


DYNO VIDEO


Been working on this car for 6 to 7 years now.This is my brothers car but I do all the motor work,build of intake,header and tunning etc.The motor has been running nitrous for 7 years without a hickup.This has been the latest dyno on a new setup.Shows that the motor is still healthy.I check the compression on the regular and the compression has only gone down 2-3 points in the past 7 years.Wich Im Impressed because this car has been through hell with us.From drag racing to highway pulls to 150 + on nitrous and still strong.Thanks to Tuner Code and now the new Nemu wich I just put on for the new setup wich controls the nitrous,methonal injection,vvl etc.It ended up doing 326 whp and 251 wtq on 4th gear.Dyno in 100+ weather.Heres the set up.

Stock Block
Stock Ported Head
BC Springs & Retainers
N1 Cams
NEMU
STI Injectors
AEM Map Sensor
GM IAT Sensor
Custom Intake Mani,N1 Throttle Body & 3.5 inch Intake Pipe
Custom Secondaries For SSAC Header
9 Cold Range Spark Plug
4 X 22 Nitrous Jets Direct Port
Devils Methonal Injection Spraying 100% Methonal Tuned to Drop Just 1 Point

I'll be posting vids,pictures and time slips shortly





FIRST RUN WITH ISSUES BLOWING SPARK AND NITROUS SHUTTING OFF AND ON


ON THIS RUN I REGAPPED THE PLUGS AND GOT A BETTER RUN


THIS RUN WAS THE BEST WITH NITROUS ACTIVATING FROM 2ND GEAR AND ON AFTER 10 RUNS ON NITROUS


AFTER THIS RUN I NOTICE ON THE LOGS THAT THE NITROUS WAS COMING ON AND OFF AND I DECIDED TO DEACTIVATE THE PARAMETER TO TURN THE NITROUS ON BY VVS AND LEFT IT BY RPM AND TPS.I ALSO SET THE NITROUS TO DEACTIVATE WHEN THE ENGINE IS ON THE LIMITER INSTEAD OF USING THE VSS TO ACTIVATE AFTER 4MPH TO AVOID NITROUS ACTIVATION WHILE ON THE 2 STEP.AFTER RESOLVING ALL THE ISSUES WE GO TO DO ANOTHER RUN AND THE TRANSMSSION DECIDES BREAK.





And just on a side note.Car is still a daily driver.With full interior and were capable of listenen to music while we run the 1/4 mile.


ANOTHER VIEW OF THE SAME RUN


TRANS BREAKS

I have a reasons and tests why I used methonal over race gas.And Im benifiting more from the methonal.We also have a 4-1 header Im building for the engine.And Im working on a second custom intake mani.But this is a stock engine.We gonna throw all the new parts on a new build.Im just gonna spray some more nitrous until the rods give up.

As long as you start doing a progressive shot of any kind i dont see those rods or bearings giving out. Just dont hammer it in there and keep on top of that tune like you are and your gonna piss off lots of v8s runnin 118 torco payin 70+ for five gallons. Can ya tell i like your methanol approach? Lol
