Finally some 1/4 times! Whatcha think?
Well I finally made it to a 1/4 mile track to see what all my work did for me. Before my best was 15.4 ...
Today was 14.23 at 97......good? That equates to more than what my dyno was at 224.....so Im thinking I have more than that...you think? The charts say Im in the 245 range..does that sound right?
Check out my dial in....I made it to the T! but lost it on my crappy R/T......PRO TREE SUCKS! I couldnt get the hang of it...I even went and tried to protest it but no chance so I bought back in and lost again on my R/T....My 60's stayed consistent all day in the 2.0 range. How in the hell are you guys getting sub 2 sec 60's on street tires and stock verters? I wasnt spinning at all that I could tell...
My 1/8th times were even better than my best at the local track of 9.299
Whatcha think about my timeslip....anything I can do to cut some more off the times? Do you think runners? MSD box...what? Im open for some ideas....
thanks guys!

that's a shame to run dead on and get beat by someone who is 2 tenths off...practice practice practice practice practice practice...
and practice some more...
not a TPI expert but an MSD is always a worthy investment

Good job man. You're only a torque converter away from 13's.

Well uh... u/d pulleys work well, when they are done correctly.
ALso, some SLP runners cleaned up a little with a ported stock base will work well too.

Good times man!!
I would have to agree that a torque converter would do wonders.
I have a Coan converter and my fiancee had a Vigilante and mine is just as good if not better than heres. (1.59 on Nitto 245/50r16 NA)
What does your exhaust consist of again?
Also bolt on a NX kit and go mid 12's ALL day

my exhaust is....SLP headers going to the SLP yipipe going to a 3" pipe where my CAT used to be and then from there is the factory 2 3/4" pipe...I think...and then to a Flowmaster.
Im running 26" Dayton street tires set at 24lbs. I dont get but a little chirp when leaving the line.

Base and runners, would be a next good mod for you. I also agree with the tq converter. Those are great times for a 305 with bolt ons

But I heard that aftermarket or even just ported base and/or runners would take away what lowend I have. It doesnt feel like I got alot now so I wouldnt want to loose anymore....
If putting some SLP runners would help then I wuld do that and then look for an aftermarket or ported/polished intake.
what do you think?

Intake and runners. I have aftermarket intake/runners on my 305 and I did lose some low end, but then it does rev to over 5000rpm at the other end. It pulls well. I'll hopefully have the dyno numbers and track times for my combo this year.

It may move your power band slightly but it can only help your overall performance to get more air into the cylinders. Breath in breath out, increase the ability for your engine to do either will improve performance.

When I dynoed the car I was still at 8* in timing and forgot to take the screens where the fog lights used to be...and I dyno'ed at 224....
So now I have it set to 10* and always remove my screens when I drag....
WHen I punch in my weight 3475/w me and my times, they come up with 249hp and 311tq..........is that correct or are the charts off a bit?

Lower control arms and relocation brackets. You'll definately need the LCARBs because your car is lowered.
I cut a consistant 1.9xs on cheapie 245/50/16 Kumho 711s with LCAs and a converter.

yeah I was thinking about getting a set of LCA and some BMR relocation brackets. Im not getting any wheel spin though and I thought that lowered cars get wheel spin bad...but not me. That might be cause I lower my tier pressure all the way down to 25lbs. So do the RB's help in the transfer of the weight?

I gotta agree with the people saying converter. I know I'm giving results from a LS1 but my Midwest 3200 dropped an easy 3-4 tenths off my time and 2+tenths off my 60ft time. Mph might have dropped maybe 1-2 but it's well worth it imo and is completly streetable
Or even with a flowmaster, a cutout might give you a little gain. I picked up .15 sec over a closed exhaust on my TA and even if it only gives you .1 or .05 for 30 bucks it's worth it.

Its only a 305, I doubt he would notice THAT much of a difference with ported heads.
I would suggest a converter. I have a corvette unit in mine and the car has a freaknasty launch compaired to before.

thats got to be the stupist thing i heard on here, thats how you get a 305 in the 300 hp area brother , matching a good cam to better heads makes the power
like i said before , there are way to many kids on this forum , post correct info next time

i recently put in a comp xe 212 218 449 456 112lsa cam and there kit ,
ported and polished the 416 heads with bigger 1.94 intake valves , new comp springs, retainers, 3 angle valve job ,
dynomax headers , with a crappy y-pipe , 3.42 gears and only 20 000 original miles on the 86 305 tpi ,, oh yeh i ported the base
still using the stock fuel pressure , timing is not correct , i think the iac is not set up , but let me tell you the car moves well ,
i need to get it tuned up properly , that 14.2 sounds great to me
