Top end power or bottom end grunt

[Tally TransAm]

i have a decision to make, need input

do you prefer high end hp or low end quickness and grunt

answer this: if you could run either a 11.8@114 or a 12.2@119, which would you rather do, why?

[Jericho574]

11.8...I always admire people that can run quick times with a lower trap. That proves you can drive and not just make the car powerful and have it make up for your lack of driving.
Just look at Tony. He ran a 13.2 at 102? and the guy he lost to ran a 13.5 @ 105....and who got more attention

[pendrgn]

low end, high horsepower is great for high speed nascar driving, but ont he street and dragging, low end torque is the thing... plus I like the push in the seat feeling :)

low end, u r not a import

I agree on both counts! Low end torque is definately more fun and is more useful on the street.

[Signal 12]

torque pulls tires, nuf said.

You changing cams? Id go for ET, not trap speed.

[Greg Kulbick]

ET good. Who cares how fast you go through the traps, as long as you get there first.

[Tally TransAm]

how about this question

heads or rearend?

90% of the races i get in arent at the track and arent from a stop

[Jeffro]

don't listen to them.

you want all out power, no matter what.

Both and be a beast!

You make more power than you can put down now. I say rearend and suspension. I always favor more low end grunt over high end. If you can make more torque at the shift recovery points than your opponent, then you should win every time. Plus, the stronger your car runs down low, the better the drivability and mileage will be.

[CrazyBosnian]

BOTH:D , but if you can only afford one, get a rear, u'll be slower on a highway, but the dragstrip story will change!;)

[slmdLS1]

go with the rear....touch the heads last...see what that cam will do with traction and 1.6-1.7 60's before you go all out balls to the wall with your heads/cam

REAR

leaning towards heads right now, they are on sale for 1049 with no core, if i sell them back my stockers i get 200 bucks, plus i can sell my current springs for liek 100 bucks

749 for stage two heads sounds fucking amazing to me

if i miss the sale because i dont get my money in time, they go up to 1249

Ryan,

I think this is an easy answer. What kind of numbers are you making now ,380 -400 right. Heads if they're done right might get you another 35 -40 hp. How much of what you've got can use now. More HP will make you king of the dyno, but won't make you faster at the track and IMO your rearend is on borrowed time even with the power and traction that you have now.

Remember that I went from a 13.6 to a 12.9 with rear end and traction, sure some of that is because I'm still not a great drag racer - but alot was because of the ability to put the torque to the road. The rear end and gears would make your car way more fun to drive - the heads you wont' notice except on a full out speed run.

JMHO

what are thse????? Patriot?

[99mustang]

I say get the heads while there on sale, and get the rear end later. Look at the big picture a year from now when you have both, you'll have the torque and horsepower and save yourself $500 by buying the heads then the rear end.

[Slow ET]

get the rear... but i rather have the 120 trap then the faster ET

[Tally TransAm]

see id rather have the trap speed too

the nittos are doing a great job on putting the power down to the ground, traction problems have been few and far between lately, but i do also know the rear is on borrowed time

ya they are patriots, i know they havents been out for a while, and because of the initial valve problem there arent hardly any dyno numbers or track times out there, but the flow numbers look promising

Havent had traction problems? Shouldnt you be in the 11's with ur numbers?

[Tally TransAm]

off the line traction problems are always gonna be there

before nittos anywhere under 60 and they would go up in smoke, now with the nittos theyll stick from a 15 punch

why?????

ET wins the race, trap speed pretty much means nothing.

[pendrgn]

trap wins the froma roll or highway race though, not that I am in any way trying to support trap over ET... I want torgue and low end power...

True that! Thank god for nittos!!!

Oh, and if you do get some heads, get a real cam to go with em too!!!:P :lol:

[redmach1]

If you don't look at it as a "system" approach, you might do yourself more harm than good. If you get the rear, then you can decide later if you need heads and cam. If you get the heads, then your low end might decrease to the point where you are actually slower than before, but with higher trap speeds. IMO if you get the heads, then the rearend is mandatory. If you get the rearend, then the heads are optional. You car will be awesome anyway, but you can't take advantage of the new heads if your car is down because your rearend exploded and you just spent $1000 on heads, springs, gaskets, etc.......

that out of 1000 dollar heads

granted he has a slightly bigger cam and lts, but i can see 420 outta my motor

plus that was uncut, i could cut mine 15-20 thousands for about .4 more compression

decisions decisions

[CrazyBosnian]

Hm, i might go for some of those pretty soon too, but i do have a special price on some "special" TEA S2xx heads;) 8)

[IUP99snake]

ryan, ive got balls-to the wall... top end horsepower... 510 to be exact... and youve got low end torque. you almost got me that time we ran em.

id say... youve got plenty of bottom end torque, and once you get to a certain point, it becomes useless. the objective is to find a good medium.

I wish i had more bottom end torque, but i would never own a musclecar again that pulled to only 5500 or so. driving a 7000RPM screamer with decent amounts of bottom end torque and a top end slap in the face is like nothing ive ever felt before. its awesome to set it in one gear, and let it pull FOREVER!!!

with my car, ill stomp on it, and ill get traction until the boost kicks in around 3 or 4K rpm's. its a sick rush.

good times. get the heads!! i ran a 12.75@124 with a 2.1 60FT time. but still!!! 124!!!! NUTS!

[97MattGT]

that's cool and all, but in the end you got a high 12 with a trap speed indicating a 10 second car.

[Slow ET]

Trap speed is kewl :twisted:

Matt dont be jealous, your trap and ET will NEVER be around the numbers anyone posted here in this thread :lol:

dude, you're sounding like a fucking ricer.

you can have your trap speed all you want, as long as my ET is lower then yours i'll be fine and dandy. 8)



of course, i got to get to that level first. :lol: :(

[IUP99snake]

i drive a street car, and having a higher trap speed is more streetable then working for a better ET. as soon as I run an 11.99, i need a cage. No thanks.

my perfect run will be a 12.00 @ 134.9

[Bryan02TA]

get the heads man, the only reason you would need the rear would be at the track. imagine yourself on i-10 and some ass hole trying to fuck with you in a viper, your rearend is useless now, but with the heads, youve go more top end power............wooooooooooot!

[97MattGT]

so basicly you prefer a car with a ridiculous amount of power and no way to really use it? Blowing the tires to oblivion in any gear and at any RPM point. Wow, that's brilliant...

[Tally TransAm]

well lets see matt,

your sixty foot is .4 seconds faster than mine, but your et is a full second slower at least

who has power they cant use???

well, you've never run a 12.6 (that i know of) so it's not "at least" a full second slower.


I ran a 13.6 with 254 rwhp, you're running 12.9's with what was it??? 361 rwhp?

:roll:
