I have been thinking about what turbo I want to slap on my build...

The one I am going with probably will support 600RWHP max....

I was originally going to go bigger on the turbo but then thought...well hell..what can 600RWHP get me?...
So on a properly set-up car, that is still near full weight, 346, A4 (3600stall), 3.23s, what should it be able to run at a power level of 550-600 at the wheels?....

**I know there are a million variables, but any experienced thoughts?**

 

Hmmmm 10.00-10.4?

 

I would think no faster than a 10.60/70 unless you have some serious wieght reduction.

 

^ Yea, I was thinking the same.

Although I do not own a Turbo LS1, so my frame of reference maybe not as accurate.

I will say is that race weight will be more, compared to a N/A or Nitrous set up as you have the whole turbo set up on the nose or in the engine bay. Also the needed safety equipment will be required. such as a Cage (6 or 10 point).

My main concern and due to the power and racewight is that 4L60e will NOT survive, and if it last for a few pulls on the dyno or down the track a few times, I will be surprised. As everyone has seen one "last", what they are not telling you is how many times they have rebuilt it and on the 10th try, it stayed together but for the life of them, they cannot figure out what was tweaked to make the difference.

So with that said. A set up like that would be fun and def would get you kicked out of the track w/o much effort.

 

well im running N/A with 461 rwhp with a 3090 race weight thru a th400 ... 10.25 @ 130 with a converter that was setup for nitrous getting it re-stalled so dont know the finally numbers yet ......
so like Blk screaming said im not familiar with the turbo setups ....
but i would assume somewhere in the lower 10's as a guess ....

 

3090 race wieght for these cars is pretty light Id think. Im over 3500# at racewieght

 

Yea 3090 is nice and light! My car is 3414 right now without driver. (But Ill be adding a Turbo& Intercooler Etc. to the nose)...

So as it looks, 10s for sure should be not a problem?

As for the 4L60s.... Yea I agree...

The car just might get a TH400.... I'd go 4L80 but Im already gonna be heavy....

 

i made 498 rear wheel and went a best of 10.22 @ 129.9

 

^^^phoenix....aint your car like really frikken light?

 

There was a thread about this same subject a couple weeks ago. My guyss is that the car will run 11.60's@125

 

That slow huh? But decent mph...

 

i never put in on a scale. but its lighter then stock thats for sure. with me in it i would guess around 38-3900 (i'm 350)

 

Thats some great numbers at that weight!

 

Here's the link to that other thread

38-3900??? stock is 38 no? and ive seen a few under hood shots...lol like lookin uu a skirt...and dont you have like everything deleted?

 

 

When I made 390RWHP I ran mid 11's. (11.5's-11.6's) full weight except for drag wheels.

 

Mid 10's no problem, but I think 10.3 maybe 10.2 if you really work the combo.

I've gone 10.0 @ 551rwhp, 3340 raceweight. I've gone 11.0@123 @ 3600 raceweight blah blah blah.

 

i went 11.4 @ 123 NA with 405 rwhp and 10.74 @ 128 with a 75 shot. this was about approx 3450-3500#'s

in the later stages of my turbo build now looking for 550-575 rwhp and looking for 10.2-10.3 at 133-134

we'll see what happens

 

ell i did say with me in it, I weight 350lbs. so i think my car is about 3500.
