ONLY 140 mph !!!!!

 

[bherman]

t That being said 5 passes in for the weekend in the hot humid air with a DA over 2000. Saturday my 1st pass was through the exhaust and 10.16 with exhaust out the back bumper with 4 lbs of boost.Uncapped the dumps and it went 10 oh something on the lean side.So I upped 2 jet sizes and gave it 2 more lbs and it went 9.9.
Sunday morn 1st pass was 9.7,2nd was 9.6,3rd was 9.8 and last was 9.6 with 10 lbs of boost No matter what I did it would only go 140 mph.Moved the timing around a little with no improvement.

Some might be able to see this>>>>>>>> ​

HEMI-ITIS, It's really nice to see your having fun with your beautiful car. Just think how much more fun it would be with a slant 6 and 3 on the tree! Brian.

You must be talking with Doc Fiberglass with the slanty option,he wants be to go with 2 thermobogs..LOL

What cam?

Comp roller mid .600 lift with 350# of pressure over the nose.

I thought you told me that the purists gave you a hard time about wrecking a perfect slant six car with 3 on the tree, maybe you were joking! Your car looks to be a lot of fun and is a bad fast street car, with a mega dose of Mopar personality. thanks, Brian.

I used to be a bigshot,,,now I'm just shot! If I said that it was pure jest as I have never seen a high dollar slanty.

I am rather disappointed with my performance.No matter what I tried it wouldn't go over 140 MPH even with 10 lbs of boost and open exhaustMy IAT was as high as 180*.
I have to find out at what temp the power starts falling,,,,,I think I was there!

 

[biomedtechguy]

Maybe you can adapt this to your needs..

Did you gain any weight over the winter?

Hey what does that tank weight anyway?

So 2 is better than one? Thought bigger was better

No,I'm the same 200 and the car is 3500.
Anyone else run a roots with an IAT sensor??

 

[bearman]

140 gees is that all. damn maybe I should ask got any paint left. At 140 I would be cleaning up a mess in the driver's seat.

Have you considered W/M injection?
And/or a shot of N2O?
Both are a good chemical intercooler.
W/M will allow you to be somewhat aggressive with total timing.
Nitrous has its benefits for providing a cool dense intake charge.
So, you were running the same MPH with 4PSI and 10PSI?

No,the pump gas passes were in the 130s. 6,8,and 10 lbs were 139 to 140 mph.
I would prefer the w/m over nitrous!!

What you need is a good front lower valance from Sled City. Makes it more aero dynamic

350# on the seat,,,,650# over the nose

video looked & sounded good
hard to see much sort of far away/little view
still cool as hell

sorry if this goes overboard,
or you don't have the time or availability/ability or software etc.
just curious

I don't remember what or if any, you have
tuning aides (electronics/computer or data logging)
can you data log at all ?
record &/or print out the run ?
see exactly where it's doing what

did you do any plug readings ?
if so, how's it look ?
I assume you have a AFR meter (can't remember what you have)
if so, what kind of AFR ? did it have in the traps or at 1000' WOT ?

maybe;
put more timing 'in' at the lower end, add fuel
better take off/launch & poss. better 60ft & ultimately better ET
& then pull some timing 'out' on the big end, add more fuel, run more MPH
if you have that ability to do so, not running out of gear or rpm
old school stuff

hard to tell in that video
but did it spin much on launch ?
do you have a way to check wheel speed ?

what kind of launch rpm ?
is there room for more ?
what kind of RPM in the traps ?
is there still more there ?
running out of gear or not enough ?
&/or converter ?
(what actual stall speed & converter slippage rate)
what kind of tires & air pressures ? any room there ?

maybe;
put a little (smaller diam.) pulley on top, than you currently have
&/or a big (larger diam.) pulley on the bottom, than you currently have
boost baby boost , add more fuel
(just don't detonate the **** out of it, do 1-2 HP improvements at a time)

Al it sounds like fun, I'm envious & thanks for sharing

MPH/Trap speed is HP available
(with a blower that's all variable for sure, early tire spin can play a big part too)
ET is the cars/suspension shocks/tires/traction all combined
& ultimate ability of the 'whole car' to work together
& proper tuning to get down the track, in that specific conditions
