I'll bet it's just over 1800 lbs.

I am pretty sure Lizzards dad's car is probably closer to 2000 to 2050. his dad is a big dude. now he does run that thing on the ragged edge every run. it would probably run 40's for anybody else. I think lizard has been mid to low 30's in it because he is normal size.

ep-PAR makes the most HP for the $

It’s by no means tricked out and lightened extremely and yes my dad is old school hot rod mentality, if it can run 4.37 then he wants it to run 4.37, lol

LIZZARD: more importantly here though is I’m glad to know I’m normal size according to EP!! LOL

Not sure I ever met a racer that doesn't know the weight of his car that is talking ET's and MPH's!

There are a number of cars out there with 250+ lbs drivers that are under 1900 lbs and also cars that are over 1900 lbs with 175 drivers! So the weight of the driver means zero...

632 CID, Dart Pro20 Heads, Big Bubba's with 4.10 gears and a 1.80 first gear, X16 VP fuel (1/4 mile setup)
1/8 = 4.29/161.4 & 1/4 = 6.75/197.8 @ 1835 lbs race weight at that time & DA = 850'
Easy 4000 launch w/.999 60', 7700 rpm shift

The engine is as Paul would say, a home brew deal.

Normal summer heat mid to high 4.30's and mid to high 6.80's (DA = 2000 to 3200)

So based on SL's previous post, it will run 4.0's at 180 plus with those new Secret Squirrel heads! but pay no attention to that blue bottle behind the curtain!

EXACTLY!

No way that cars runs 30s with a 615 at 1900 no mind 2000 lbs.

Al, what do you think the numbers are your engine in my car at say 1905 lbs.?

I'd say .057 to .063 slower in the 1/8 and .09 to .10 slower in the 1/4 as a good ballpark estimate.

Another thing to consider regarding performance vs weight. This is not the only factor in this equation! There's a good amount of performance just in the trans alone never mind the 3rd member and ceramic bearings! Take a typical PG trans for this setup that has 8 clutches and no low drag gear or light weight parts and swap out the gear set to a low drag roller deal, lightened with 6 clutches, you will certainly see two different time slips.

agree 100%

I am in no way arguing the points made but I will guarantee that lizzards dads car is closer to 2000# than 1800# and I know that there are no tricked out light weight pieces in the trans. now that being said he probably has the most aggressive converter humanly made and leaves at prolly 5k with sub 1 flat 60'. it prolly is a true mid 40 bullet for anybody else.

ep-lizz dad says if it ain't leaving knee high what is the point

Ed, I'm sure you know that I believe nothing on read on the forums and half of what I see with my own eyes.

That said, The reason I know this car is no where near 2000 lbs. is not only would it be quickest if not the fastest too, 615 20 degree in the country but KB's dragster is sub 1800 lbs and has run a tenth quicker with a whole lot more cubes under those heads.

Further yet, another 20 degree PAR engine with a whole lot more cubes has run a best of 4.31 at 1830 lbs. and the driver of that car is 275 lbs.

What is Lizard's dad's name, first and last, I'll ask Scott about his combo.

ED I run with all these guys an there are several 615 running .30.s...an most are in the 1840 to 1895 range...You can’t compare KB motor to nobody’s but mine an it still ain’t as on the edge as his....

I'm not sure how fast my SR20 will go, but I can promise whatever I dial it can go atleast that. And I have yet to dial anything slower than 4.38 yet.

I know we are talking about dragsters here, but my sr20 PAR 632 has been 4.78 @ 144 in my 2525 pound door car with the converter no where close to being right for maximum ET naturally aspirated. So I see no reason why is hard to believe that 1900 pound dragsters run 430s.

lizz can tell his dads name if he wants to.

I also have a friend who has a sr20 632 in a 2300# door car that runs mid to low 4.60's and went 7 teens at 190 at d1 at Dinwiddie last year on motor. single 4 barrel. he sprays it some at pdra and goes mid 30's. I will give you his name if he will let me. PAR did it as well.

he not leaning on it either. he is scared.

ep-PAR builds fast stuff man

I bet cmanuels car aint that light either. but I could be wrong

ED’s car would run in the .30s with PAR standard 615’...but they will definitely slow down in the heat...

it will slow down after 1290 tunes on it whomper

ep-couldn't resist that one

You guys are cracking me up!

My converter combination is pretty flexible.
I've been 4.78 on motor. 4.45 on 1 system. 4.38 on 2 systems. And I don't change anything.

While I wish that were true, it’s not, low 50s is more realistic, maybe a high 40 in mind-shaft conditions

My only purpose in responding to this topic with original post was to say I know my dad’s car doesn’t have all the lightweight tricked out parts, it’s not a tricked out 615, but it is a 615, and it can run in the 30’s with my dad driving, it’s went 32 with a lightweight driver in it. I completely understand the entire concept of being able to run low ET’s takes a combination of weight, horsepower and etc, and I’m by no means saying my dad’s is the fastest and his engine builder, as well as mine, is the best or better than someone else. I was just responding to Ed’s comment that I quoted. I mean how many people think upswept Borla’s with the mufflers is the ultimate combination for speed and ET?? My dad enjoys going fast. It’s caused many an argument between his way of thinking and mine but it’s his dime and his ride so who else has any room to say anything. His motor is at PAR as we speak, got the call today that it’s ready to be picked up. As far as the exact weight goes, I’m sorry he just mainly races at our local track and they don’t have us cross the scales after every pass. I was told by a local chassis builder that he figures my dad is between 1870-1890 depending on how much he weighs. Not gonna get into a pizzing match just responding with what was being stated.

LIZZARD: I’m more ashamed Ed doesn't know my last name!! LOL, little fish in a big pond
