does anybody have any track or horsepower numbers after switching to a 52mm throttle body?

TPI-Formula350-

i really didnt notice if the 52mm TB helped on its own because i installed other mods at the same time. It sure didnt hurt.

Hi Matt

Those are darned good times for the mods listed. I also have an 1989 Trans Am with Trickflow heads and ZZ9 cam to meet the times you have posted. Anyways I'm running a 52MM throttle body and I feel it has helped. With the 700R4 transmission I'm turning to 6000rpm in first gear for the 1-2 shift point and I feel the engine needs all the air it can get. Allen

1/4 mile, 13.30 and 103.59 last time out. Looking for high 12's next run.

i just installed the throttle body. can't really tell if it did anything. im hoping to possibly go 122.70's to 12.80's on the stock heads, cam, intake runners, and torque converter before i install the tpis big mouth kit with afr heads and zz409 cam.

TPI-Formula350-

yeah nice times. I've been seeing how fast I can go with external engine boltons. Best Ihave managed is a 13.21@104.6 Mods listed in sig. Anyway would be cool to see someone break into the 12's w/just boltons. good luck with it.

Damon

I agree- nice times for the mods. Best I could ever get out of a basically stock L-98 was bottom basement 13s, throwing every bolt-on part at it I could lay my hands on. I had SLP runners on mine and a ported upper plenum, though.

Sorry Matt, im calling BS on those times you posted...

stock heads, stock intake, stock runners... hypertec chip?? stock air cleaner, stock cam..

come on now.. you see what mods the other guys have and are running the same times... theres no way you are running that, especially with a hypertec chip.. and stock stop end..

sorry, not buying that one.

air pump is untouched and ac blows icecubes. i have gutted the catalytic converters but it ran 13.50 through the stock manifolds and converters.

Just clean up your plenum directly behind the T/B, and you will almost get the same flow as a larger unit for FREE, +labor.

well i stand correct and i am not afraid to admit im wrong. and i also appologize.

your car is a freak.. funny this i just grabbed my time slip.. and we are exactly the same to the 8th mile.. then for some reason i die off at only grab a 13.94 @98.89.. weird.. but your mph @ 82 and the 1/8th time are almost idential as mine.

damn those 3:23's

GTA matt

iTrader: (1)

those times were with 3.23's. i just installed the 3.73's 2 weeks ago. the difference is much better then any other mod i have done. at the same time as the gears ive installed the sphon torque arm, LCA's and drag radials. it is MUCH faster now.

by the way, apology accepted. nobody believes what i have done, not even people who've seen me run.

Way to go, making a huge ASSCLOWN of yourself...

I havent upgraded from the stocl 48mm with an airfoil to offer you any results.

Bu I am running the times in sig with the stocker, 48mm that is,

vladicore

i have a 91 z28 l98 that has stock bottom end and heads, accel superram intake, slp runners ported plenum, air foild knn w/ mod box, stock tb, no smog pump, no cats, accel wires and ac delco plugs, w/ a built 700 and a posi 3.23 gears. and i wont even post my reaction and 60ft times because they are that terrible and i ran a 13.7. my buddy w/ alot more respectable reaction ran a 13.2 in memphis motorsports park on a hot humid day.
so i can believe someone is running low 13's or high 12/s w/ bolt ons but i also agree you car is a freak! no other way @ it!

TPI

Well,

hes puts ideas into my head that
my car can get there ..
motivates me to say the least.

you have a Speed density system correct?
maybe the MAF car requires more to achieve those ETs?

ill have slips of what I put out within the next month.
(cross dem fingers ))
highly unlikely event I even crack mid 14s

brutalform

Best times 2 1/2 years ago, with a ZZ-9 cam, trickflow heads, and S/D.....13.00s @ 108. Never broke in the 12s with my 350, but probably would have with my MPH. Oh yea, I had all the other stuff too!

I also hollowed out my cats, and picked up "zero" at the track.
