just wondering how much time i can expect to shave off my 1/4 with a valve body upgrade from sgp. Any input would be appreciated

 

it really depends on how much it is missing the shifts now, it wont really save or help you unless it is fixing an issue that you already have...


thanks

 

I have to shift like 5 or 600 rpm early and it is super sluggish

 

Look for a post by GurgenPB - he had some datalogs and videos status post SGP valve body install.

 

the sgp vb is sluggish?

I know that it's faster shifting than my stillen vb which I have to shift 500-600rpm earlier.

 

I beleive he means without the VB upgrade.

 

Can't say for sure how much it will take off in the 1/4, but it definitely shifts quicker and harder with the VB in manual mode. Mines a head snapper!!!!

 

what about GTM VB ?? they have like 3 stages

 

They have 3 different tranny upgrades not 3 different VB's...but I know what you meant, I think...

 

I looked at gurgens post and all I saw was the actual video he made

 

Hmmm... as I recall from the graph, the shifts drop from around .5 sec to .25. About twice as fast - I'm going by memory though so don't hold me to exact numbers... Maybe it wasn't Gurgen that did that data log - thought it was him...

 

Depends on the software in ecu as to how fast the cut and ramp back up the ignition advance is...tcu tells ecu when shift is complete.............2 shifts or 3 in your quarter?

You can data log ignition advance just before, during, and after and read in milliseconds time slices.

 

Not sure how it will help your times, but just for driveability's sake, I think it is a good way to go.

I could hardly drive the car with the OEM VB, and the Level 10 VB is largely insufficient at full throttle. With the Level 10 VB, I need to shift early in teh lower gears, although the highe gears are typically precise.

I spoke with Thomas at SGP and I plainly asked him if the SGP VB would miss a shift if I kept it in full auto mode and just rammed the accelerator to the floor from a stop. He said it would not miss a shift. I will hold him to that guarantee, and that will make me very happy.

 

So am I crazy to think this thing might save me .2 sec?

 

are you going with sgp?

 

Eventually, yes.

ProTorque is 10min away from me, so i will do the SGP VB and ProTorque TC all at once.

 

So what's the turn-around?

This is a "ship me your VB, we change it up and ship it back to you" type of deal right?

 

right, the answer i got was anywhere from 3 days to 2 weeks

EDIT: I'm hoping its not the latter

 

and whether or not you consider the "out of your hands" time or not. We are doing a lot of these so we are having always having parts coming in and out. It also depends on the back log and how badly your VB is messed up or if it has been modded before.

Just call us!

 

is the price the same if you redo a modded VB? I have the stillen VB. Can you pm me a price. Thanks
