With the mods in my sig and a 17' mt the car went 11.63 @ 115mph. Cutting a 1.6 on motor. This was the first night I had the car out after the tune.

well according to the MPH i'm gonna guess maybe a bit more?

a head cam car going 115? i'd say there is 5 mph hiding somewhere in there.

as far as with your current results...maybe a tenth or so depending on how well you can get it off the line. with only a 3500 stall and prob 3500+lb raceweight...unknown suspension mods it is hard to tell.

Suspension wise it's not really anything. Eibach pro kit and umi adj lca / relocation brackets. It put down 380 on dyno.

definitely low on power for only 380 to the wheels...for a el torro and tfs heads...I would have thought at last 120s...unless you are racing in 8000 da conditions

I was expecting more on the dynojet, but then figured eh, numbers don't mean everything. I was gonna see what it'd do at the track. That was the cleanest pass I got of the night. I don't know what the da is.

I don't know if maybe my ls6 intake is maybe holding back some hp or what.

what gears you got, and if the cars is hooking well it will kill a few mph. i have a nova that runs 11.50's at 115mph w/ 1.55 60, you have a bit left in the 60 and i bet even with a dyno tune your likely still lean at the track the ls cars should have a few extra mph but i think your pretty close.

its got 3.73's. I will probably take it to test and tune this friday and get a little more seat time and find the best way to launch it and see what it does then.

i was trying to figure the DA but couldnt. All i know is the elevation is 1500ft and the temp was 42* at around 1 am sunday morning when i made the pass.

Ok I think I did it correctly and came up with a DA of 1921. If that is correct and could possibly effect my et, I still don't know why it only put down 380hp.

it's not good but it's not terrible either maybe 1-2 tenths max

Was your converter locked? Is there a cutout on the car , if so was it open? Are your heads still as-cast or have you had them worked? There are alot of variables here that could explain your dyno numbers but my car made 382 rwhp on Geoff@EPS dyno and on a hot August day it went 11.83 @115 and I had a 3600 fuddle() 12 bolt 3.73 gears ported 241's TH350 and it weighed 3565 raceweight. 60 ft was 1.68()

Locked, no cutout, as cast heads. Was about 85* that day. Maybe I was just hoping for too much thinking it'd make 400.

this is an identical et and 60ft as my car ran on a 100shot before the heads, cam, lt's, and ls6 intake.

You might want to check your stall on the big end and see how much converter slip you are having. My buddy's 99 ws6 ran the same 1/4 time as you but he put down 118 mph with a Vigilante converter with the stock 323 gears. It made 405 on the dyno but I think that was a happy dyno.

Some people have had good results with PTC converters but I haven't had any at all. Burned 2 transmissions and still had a balance problem besides that.

with it locked i would expect around 420,how is your intake setup,ls6 intake is not the reason your making 380 locked.
what lid,maf?
brand longtubes?

SSmoken

iTrader: (26)

the tuner didnt say anything about converter slip.

thats alot of hp. id expect that through a 6speed. i dont know if ive seen any autos putting that up but maybe im wrong. all lids are the same, a stock maf is fine, and all longtubes are capable of the same numbers for the most part. Anyway to answer your question its an slp lid and QTP ( which i have in my sig ) longtubes. so im pretty sure neither of those are the reason.

You can lock a converter on the dyno with the tuning equipment the dyno operator is using. Im talking about at the track on the big end.

I understand where you are coming from with the exhaust because I was just like you in my thinking about longtubes until I had to see it with my own eyes. A friend changed out his pacesetters (a header everybody uses) for some ARH's and re-did his TSP y to have a better merge and ended up gaining 18 rwhp. So all longtubes are not the same and I don't think he gained 18 hp from just re-doing the y

Edit: Just found this on the QTP headers and Y https://ls1tech.com/forums/generatio...er-y-pipe.html

that cam camonly should make close to 400rwhp on a locked run.when your cam only no parts are the same,and boltons are fine but some are great.hmm maybe stingy dyno
those headers a good but you can pick up mph by swapping to a ftp lid/85mm maf and get some sort of ram air.
