How One Thing leads to Another

[THensley]

Lit me start and thank the venders In Alphabetical order
Caspers (Justin)
Fullthrottle (Marianne and Steve)
Racetronix (Mike)
RJC (Jason)
Yes I have taken my car to what I think is its SAFE limit
What is in the sig will be taken to the next steep. I started at Fullthrottle for bigger injectors that lead to bigger fuel pump and lines.with room to grow into a E85.
I have. a new pump and hanger from Racetronix ship from Fullthrottle and my old Hot wire no longe will work.
My Holley harness from Caspers has a designated 30amp circuit, so I called Justin and he sent me 25ft of #10 red and black wire with shield with a plug installed.If you have a holly from Casper this is a must have. It came just like the I/O plug with lots of wire so I would have enough wire to do it my way.
Next was a new turbo and I spoke with Patrick and HPT and a few more and all took time to help Thanks Jason for time and real life experience with the turbo and the great Price.
Ractronix has been helpful with E85 sensor with plugs and connectors to hookup there pump and E85 sensor to my Holley.
I have made one pass at 10.8 @ 125mph and 8 at 11.00 @125 unable to repeat 10.8 pass. I had hoped to get the 5857 with 60's and 255 pump solid in the 10's. But I broke my second sprag in the convertor. This convertor has been replaced with a convertor with a clutch, and if it works I'll report back.
The new combo is a Next GEN 6062 Bosch 132lb a 450 pump. I hope to start running this new combo next week and spend a few weeks dialing it in on pump gas and ALKY then introduce E85.
Thank you venders and fellow Buick posters This new combo has been inspired by you, and I will need your help to make it fast.

It looks like you are on the right track with the upgrades.

Quick question; why a 6062? With your heads and cam (and new fuel system) I would think you could easily go with a larger turbo. I have Champion Irons and a small flat tappet cam with a PTC 17-blade converter with a HPT-6466 and it lights off and the response is like a much smaller turbo. When you go to E85 spool up will be even faster.

 

[THensley]

I was looking at lots of turbos and felt like 750 hp rating would be be enough and my first choice was 5658 the HPT 6466 was highly recommended
But my conversation with Jason he led me to the 6062
But most of all I like getting it done with less. And really the 5857 on the street with a 600 hp rating is quit impressive and hard to put the 500 hp I estimate I have down on the street.
and at the track people that have turbo knowledge could not believe it was a 58mm and one fellow said I was just lying my ass off. but did not have Ben Franklin he was willing to part with to find out. and 840 hp 6062 rating is a lot. and with a cam with less than .5 lift with Champion Irons Im giving up a lot.
Funny thing is I have a set of GN1's with 1.6 rocker and Timm in Phoenix has made me a supper deal on a very nice cam.
Like some Buick guys it was just a dream car to look cool and smoke your average Corvette and Mustang I can do that and .I want to keep doing that with out it lookin like I have a 88mm turbo and a parachute on the back bumper. If this turbo will really push enough air to make 840 hp and I think I need that much Ill cross that bridge, But today I have specced the new fuel system for 850 hp on E85. The champion Irons will do that with a 215 cam at .550 lift and I think I can do 725 with my 210 at .490 lift
the real trick is the convertor.Im traveling a road not often traveled in a Buick but a road that is used quit often in the new muscle car. with 60 ft times in the 1.6 and low 1.4 If I can get the Buick to do that ill be in the low 10's @ 130. I f I can crank a 100 more hp out of it too.

You are well past the "while we are here" and into "I got a few extra dollars"

Justin and he sent me 25ft of #10 red and black wire with shield with a plug installed.If you have a holly from Casper this is a must have. It came just like the I/O plug with lots of wire so I would have enough wire to do it my way

Update its #8 wire. you will need a few parts from Racetronix Plug for the new pump and a plug for sending unit to fuel level. Ill post pic because I can't figure out how to post link ,and I used 10 in of #10 to solder to the #8.
No more relay at the back bumper from the Hot wire ,that has been one of the best upgrades. This is a nice steep forward with Racetronix new hanger with # 10 wire and better ground setup. and large #8 from a 70 amp fuel pump relay. you can put any pump back there you want. I did add an extra ground ,probity not needed.
One peace to the puzzle has been on a short delay. but will ship soon.
I went to Bats last weekend and found out I don't own the only money pit. It was a great time

I have made one pass at 10.8 @ 125mph and 8 at 11.00 @125 unable to repeat 10.8 pass. I had hoped to get the 5857 with 60's and 255 pump solid in the 10's.

Weight of the car?
What is the backpressure at?

3480 that day with me in it. Back pressure I have no way to test. will I could just don't.
The day I made the 10.8 pass I was fighting a bad exhaust leak and could not hold boost above 22 but all 3 of my 60 ft was 1.6. @ 123-125 mph.
next outing all passes were 2.0 + 60 ft @ 125mph. good and flat 25 lb boost and I added 108 octane and 5 degrees of timing with no help with 60ft.

Unfortunately my money pit decided to bend a push-rod on Saturday and I couldn't drive it down. Still was a lot of fun as always. I have a spreadsheet with almost all the money I spent on this car documented.; hopefully my wife never sees it

3480 with driver with your combination on a 58mm billet turbo you really should be looking at backpressure when trying to push things to a point where you are experiencing the potential snowball effect..
Turbos make the power
Knowing what your turbo is doing is a major factor in performance.
Pulling your 58mm off for a 60mm without any bp data is the fastest way to set yourself up for the snowball effect in other areas.
Your 58mm combo has low 10sec potential if your not hitting super high bp with a hotter tune-up and the car working correctly to lay down a 1.4 60ft with a strong 330.
Unfortunately turbo ratings can be misleading as they work differently on different platforms.
That's one of the reasons why looking at the backpressure is super important.
Is your car externally gated with a co2?

 

[Mr.Spool]

One of the key points in running a small turbo combination is to understand the 60 and 330ft is the the most part of the pass.
to get the et out of the cars I've run on stockish builds for example,On an old 58mm cast turbo (ta49) i had to get the cars to 60ft low to high 1.4s.
That netted a 6.6 1/8mile and 10.6@125mph.
A 1.6 60ft yielded an 11sec pass like you describe.
Those cars the raceweight varied but some passes were made with weight 3800+.
the 58mm combo needed the whip on the tuneup and the turbo was all in with a car that was setup and took the hit right away.
Not easy, took time and good driving.
What's nice is leaving off the footbrake.
a bigger turbo puts these cars easily into 10s with a soft 60ft and a very mild tuneup.
Especially with heads and cam.

 

[Mr.Spool]

Here is the 49 58mm tuneup data
On c12/c16 36 degrees of timing and 25/26psi of boost.
On Pump gas alky twin nozzle 26-30 degrees in 1st/2nd gear,26 degrees in 3rd 30/32 psi boost would vary based on air quality.
Now before people go try this
Understand this is a hot tuneup with me pulling plugs and looking at afr and assuming responsibility if things let go.
Cause your not running in the 10s on a 58mm on a stockish type build at 20psi and low timing unless the car is a tin can

 

[Mr.Spool]

And the driving style was as aggressive as the tuneup

 

[Mr.Spool]

introduce E85.

This alone will change backpressure say vs the 108 octane you ran.
I go bigger on turbine wheel and ex system and fuel system to compliment the 30% more fuel requirement.
