Whats the fastest 350 cubic inch TPI car that you currently know of. No nitrous, no supercharger and no turbos....Just all motor including heads/cam...but has to be fed by TPI induction. Just want to get a baseline of what a bolt on/cam 350TPI will do 1/4. Any input would be appreciated.

 

well i know of several TPI induction cars puttin down around 300-330whp.

thats good for mid low 12's.

some vette guys are 11's i believe

superam cars which is a form of TPI, are doing 11's easy on 383's.

but mainly TPI n/a cars are doing low 12's. thats about the most your gonna get without some weight reduction and more mods for strip performance only. i dont think a high 11 is out of the question tho with a great launch/chassis setup/trans/gearing/driver.

my car with full exhaust and gutted airbox for power mods and 2800 stall has done 13.88 at 98 but has trapped 100.9. on street tires

on slicks which i will be gettin soon, i should do mid lower 13s. i hope for 13.5's for now, then i'm workin on hittin a 12.99 if i hit 13.5's with the slicks only as my next mod my next time out at the track. we'll see

 

See signature. I know of some Super Ram cars a little faster but I'm going to fix that.

 

i need some help on quarter mile times i want to know like estimated what other 3rd gen owners think i wil run ,i have a 350tpi in my irocz and how much as an estimate will i run if i install a 2400 stall b &m torque converter,holley 58 mm throttle body,k & n drop in dual air filters,ported plenum,accel super stock wires,edelbrock high flow tpi runners,edelbrock high flow tpi baseplate,hooker shorty competition headers,hooker y pipe,magnaflow 3 inch exhaust,and i have a 3:27 rear end posi unit<thats all and eventually later on i plan to install a cam in it any recommendations on a cam with a noticable nice rough idle thats suitable for a tpi street car noting 2 big,i want a nice rough idle,and how much estimated hp do u think i can make with these modifications thanjs ill appreciate it alot

 

you'd have pretty much my car minus the TPI base and runners and slightly smaller converter and different exhaust.. but similar mods

i'd save your money and not by the throttle body. you will have plenty of flow with the stocker 48mm or else get a 52. 58 is abit too big.

with those mods. you will be mid high 13's easy on street tires and a 1.90 60 foot. thats where i'm at. near 100mph traps in the cool weather. another guy i know has TPIS TPI base SLP runner and runs 13.6's at 100mph or near that on street tires. 1.9x 60's but he has stock converter and 3.70 gears

slicks/radials will put you near 13.5's i would guess. i'll find out for yah as i'm gettin slicks soon
