General Supercharger Thread.

I'll repeat myself....it's good to see consistent HP numbers on the Harrop installs.

I'd like to see the TQ curve as well....

 

I wonder what pulley and injectors and such that one has.

 

What was other tune?
What size Injectors and pulley?

 

2 months between runs?, and 20+ mph difference in start isn’t ideal for claiming any gains.

I’m guessing they did not hook up the optical sensor due to the mph on the scale instead of rpm, if so there won’t be a TQ curve to look at.

 

I may be mistaken but I think they would be the same for both since OTT is a remote tuner service.

 

What parts did you use?

 

He explains the reasons why that was done over on the tw thread. Something along those lines, the Dyno shop didn't hook something up

Don't know pulley size

 

To make the SABM? Or to monitor temps? I did it the cheap way using 3” duct plate (2) and 3” silicone hose (1) hose clamps (2). Same ones listed on the sabm thread think it was under $20. Also need a 3” holesaw.

I’m using obd fusion for temp monitoring.

 

so are you ~4 degrees from ambient now?

 

Normal driving was consistently 25-35 above. At 70*-90* ambient. In the cooler morning much less. Also noticed the IAT drop quicker than before.

 

I finally got a MPVI2 so working out details with John/Justin to remote tune it, won't be on dyno this time but will log it via racelogic performance box, should be more "applicable".

 

Sweet! Keep us posted on how it goes. Where'd you snag an MPV12 from?

 

The lowered Tundra build:

There is a gen 2 RCSB on here too, forget the name.

 

Received my Dragy today from Amazon. I'll try to get it set up and run some times on Wednesday if work time allows.

 

Doing my dragy run tomorrow

if weather holds

 

Thanks for the link! I finally got the jeep out of the garage and on the trails! And just now laid out the parts for the Tundra!

 

I got mine too. I just did a little playing to figure it out, but have to try and get a good run in. Seems easy to use.

 

No worries. This one is pretty interesting too, not lowered though.

This was my truck actually. The torque clamps don’t work on my truck so we had to use the drum but forgot to recalibrate it for fourth gear on the final run to compare my baseline. But the baseline tune was VFTUNER harrop file.The OTT tune we did with HPTUNERS. The previous run in 3rd gear was 459 Hp/472 tq.

650cc injectors
80mm pulley
JBA long tubes no cats
5.29’s
SABM
35’s

The baseline was like 104 degrees that day and last Saturday was 96 I think.

 

Here is the last 3rd gear run if y’all wanted to look at the TQ curve. Idk if it means much being in 3rd.

 

Make sure you floor it this time

 

not ideal, but inline with my other runs. I'll do better later today.

doing a run in the Plaid as well...because.

 

See on the report where it shows 0-60 (1ft) on the bottom left? Does that indicate the time with 1ft of rollout? I thought that was how most publications do the testing and report their time.

 

dunno
I think that's to replicate a drag strip trip lights.

but - this was in 4HI - my a/c was on, and no nannies were turned off, & tow/haul was off. not excuses, just saying it was not ideal.

next run, I'll watch the MAF reading..i want to see how close I get to the 512 limit.

 

I swear you are incapable of giving it full boosty bois

 

You are not wrong.

 

What's everyone running for air filters on the maggy? Also, ordered the insulation sleeves to do the following items. Heat exchanger lines, intake tube and adhesive for the airbox itself.

 

I'm just using the TRD intake setup myself and will likely do the SABM et Al before winter...

 

K&N POS that superchargers online sent when I bought the Magnuson intake. I actually just bought an AFE dry that I'm waiting to install.
