Making a 4 seconds drag 1/4 mile Covet

I'm trying to make a 4 sec covet, I think I'm not that far off.
Right now, here's the modifications I made to it :

• Covet V6R4 hillclimb wheels and tires
• 500kW N2O
• SBR4 2.5L F4 engine
• AWD transfer case with lockable front and read diffs
• 7-speed sequential gearbox
• 196 PSI turbo (Not very realistic, I know.)

Currently, the best I managed so far is is 5.3 sec, so I'll let you know if I manage to go in the 4 sec territory.
I think the next mod I should make is actual drag tires, but I want to keep the car drivable.



Any suggestion ? Thanks.

 

I made it (included : kicking the N2O too early, engine blowing out like crazy)

I made a stage 6 turbo (250 PSI wastegate start, 300 PSI wastegate limit, 350 PSI turbine)

 

Try removing lights, body panels, glass, extra seats, etc, until it's just the car frame, chassis, engine, and maybe a drivers seat for realism

 

Yup that's a good idea. I also plan to rely more on N2O and less on boost.

 

also, add VTEC
