finally broke 10s

[ChevyKiller]

I was running a big 76mm PH set-up and that's one of the big reasons why it took me forever to spool. Literally 3-5 seconds to see 10 psi.

By 'Real' Racing I was talking heads up and brackets and referring to racing the guy next to you vs. going for an ET.

I certainly wasn't trying to downgrade your accomplishment as I think it is AWESOME. Like I said, just venting about some of the crap I went through with my particular set-up. On the 67mm, spooling wasn't an issue, but I ran out of steam on that thing after 16 psi and wanted more. The bigger set-up is what seriously challenged my ability to spool, no doubt.

I also have a 4 speed AOD with no lock-up and no kickdown which played a lot into my turbo troubles as well. I look forward to hearing more things from you!!

ChevyKiller,
Knowing each setup is different I can only expound on the results other PowerHouse customers are seeing. As for me, I can cut a good light while getting 1.4x 60' times. For example, on the PowerHouse turbo, I was able to cut 0.10x lights while getting a 1.4x 60' times this past weekend while running 10.5's. This is with a 4r70w off a transbrake on the 67mm turbo.

In fact, I need to keep boost at bay off the line. If I just floor it and leave at stall, I see all 18lbs well before the 3 amber light. I only need about 5lbs just to get the the car to squat a bit and roll out, then it's WOT & full boost.

The V8 kit, which Redfire (Will) and I run almost every weekend, puts out enough boost that we both can blow the tires off the line and that's well before 3rd amber.

I know you had a modified kit that may have resulted in different results but for those who don't take the route you did, the PowerHouse turbo is a great track & street kit.

As for Rygen's (Todd) RT, he does not need to sit on the green for 2+ seconds to run low 11's. He only did that since he was ET hunting for 10's and didn't give a damn about cutting a light. He was also having 3-4 trany issues. Since he's running a V6 with street rims with mostly stock weight, getting a "just right" RPM/boost is why he took his time. The fact he got into 10's with a V6 is very impressive.

No doubt very impressive and even 'mag worthy' IMO.

As I said, I didn't have a problem either on the 67mm spooling. I was looking for a 'monster' track car back then and went with the big 76mm on the PH with a blow through set-up. That's when I had the spooling issues.

After we took it a part, we discovered the exhaust housing Mike had put in my 76mm was a GINORMOUS D-trim, and then it all made sense why it was never going to spool under 5 seconds. The D-trim is designed for a turbo on a big block...lol

Anyway, we ended up using the smaller Q-trim exhaust housing and then I spooled quickly but my heat issues became ny nightmare. Now I was spooling so fast (full boost as soon as you went WOT) and the AOD was hitting so hard that the turbo produced instant heat way too fast for intake and TB to handle it. So I started blowing head gaskets almost instantly.

I was still determined to make it work and I still beleive by fabbing an additional water aftercooler and using an icebox at the track, I could have made that set-up work. It's just that, at the this time, Jim Bell came along with a good deal on a KB, and I had a buyer for my turbo so it just made sense to make the switch.

That's why I am where I am now or I would have made my turbo set-up work by now. Using a custom set-up and swimming in 'uncharted waters' was the source of all my woes. That's just the nature of developing something new. So I'm not 'against' turbos by any means and understand my set-up had specific issues that was relative to my specific set-up and don't weigh my experience to the standard PH kit. I have in the past before I had all the facts regarding exactly what issues I had and why I had them.

I'm blown away by the accomplishments of you V6 guys. Congrats to all of you owners, shops, and manufacturers that are making these #'s happen.

BTW, are the V6's easier to get into the 10's than the GT's if both are equipped with a PH turbo?

 

[ZmanM3]

Wow, thats awesome!

Tough question to answer depending on what you mean by easier. I have a lot of respect for Rygen and other pushing their daily driven V6 this hard but it's hard to ignore the fact that a larger displacement will have a greater potential power foundation when all other things are equal (i.e. power adder, reworked short block, etc.). However, as you probably know, going fast costs money. Going fast and doing it reliably is even more expensive.

Keep in mind that all three of the 10-second PowerHouse customer cars do not have stock drive trains. We all have re-built engines, rear-ends & suspension to handle the power and put it to the wheels.

 

[Rygen]

And another point on my transmission. I may get lucky and the 3-4 shift issue may be something minor, but in all honesty my transmission is on borrowed time, be it 10 second passes or 11 second passes. So cage and transmission are my next two immediate projects.

That's good info. I wasn't sure if the V6 had certain advantages such as weight. I know they have advantages of lower payments and insurance. LOL

ROFL ......

Congrats Todd, those are incredible times.

Way to go Todd!

That is a beast no doubt
