TE-66 combo help

[SpeeednV6]

It's been 5 years since I've had her running. I purchased 60lb.er's a while ago and have not put them on because I see that there are 80lb.er's on the market now. There is E-85 out there now which presents a whole new dilema. My goal is 10.5 with 20-22lbs. of boost. My current set-up is: Precision TE-66 turbo, stock-heads, 50lb.er's, hot-wired Walbro, and all the other supporting stuff. I will be putting Champion heads/intake back on. I'd like to run 93 & Alchy or 100 octane. Thanks.

It all depends on your goals and budget. I had the same goal as you 10.5 street car and decided to go the E-85 route. I'd check out the E-85 section and give it consideration as it's a cheap alternative to race gas (you'll have a grabber when you price out C16), plus you wont believe the low end torque you'll get and power it produces. It'll make that 66 spool like a 49.
I've never been a fan of alky but lots of folks have made it work for them with good results too. Lots of ways to get to 10.5, just depends on if you want to get their with C16, pump gas with alky, or E-85. I like getting points at the grocery and picked up my last tank of E-85 for free!!

 

[SpeeednV6]

I'm leaning towards alchy, but If E-85 is around me, I might lean that way as well.

 

[jasjamz]

I like them both but you need 120lb injectors and a double Pumper in the tank to run that number on E85. Also forget it at 20-22 psi with ported irons unless you have like a 1.29 60ft LOL. Don't worry about how much boost you need to run to reach your goal. Just make sure you avoid detonation or running it lean.

I agree with jasjamz. You need a lot more engine to run that number at the boost you want to. Race ported aluminum heads, good converter, and be able to feed it. 100 octane won't cut it there without alky.

I see everybodys point. So what should I expect with my current combo? I have brand new 60 lb.ers and debating if I should go bigger high Z's? I will be installing a FMIC and ported irons and intake.

I say run what you have. If the FMIC and ported irons are around the corner the 60's can take you to 10.6's using a dual nozzel alky kit. Any faster than that, bigger injectors will be needed or you'll be on the edge.

i believe grumpy was only running 60# injectors and dual nozzel alky kit, and i think a single intake pump in melissa's car 9.94?

 

[bison]

Dual nozzle with 60's will go 9's. I wouldn't want to be relying that much on the alky as a supplement though. It's ok in warm air bit could be a problem when it gets cool out. Throw some voltage at that single pump and it will flow quite a bit more at high pressures

 

[SpeeednV6]

Wow...9's? I think I would tear up a crank on that pass. I usually run 100 or 110 octane. If I get alchy, I don't think that I would push it. Is the Precision 66 a good turbo? It's a beast on the high end but a tad slow at spool-up from a dig. I thought bigger injectors only because they were available in high Z's. This is my 3rd set of injectors and want to be satisfied for another year or two.

You wouldnt tear up the crank. The pistons and caps are more prone to failure. The Precision 66 if its a T66 compressor and 76 p trim ex wheel it will run very low 10's. You need to have some really good parts and some tune time to get the most out of it. With a proper converter and tune that turbo spools fairly well also.

Wow! I know the IDC was high too! That's the edge I was talking about.

 

[Grumpy]

Wow! I know the IDC was high too! That's the edge I was talking about.

the set up was not maxed out yet We have over 20k miles on that motor. It is a street car that she DRIVES. It's sitting here on the engine stand waiting for a new home "maybe" back in the Mazda. When we race the car we don't go there to run 15#s of boost .

 

[87WE4BOOSTED]

We all know you're the exception to the rule. Me personally, I'm not reaching for max effort with alky!!! Race fuel only! So, tell me where the IDC was on the 9 sec pass? You just don't see alot of people running 9's w/60's and alky! Next outing for me will not be at 15# of boost. It won't be MAX effort either. I'm still on my learning curve w/new motor. I still feel that's pushing it on 60's, hence me telling the OP 10.6's with alky. Some people LIKE living on the edge.

I don't think mid 10's is pushing it at all with 60's and alky. I went 10.40's @ 129-130mph in a full wieght T Type with a set of 55's with no alky on race gas . That car went 10's for 4 years with no issues at all. The T-Type had a similar combo to what the OP is planning. It still used the factory crank, rods and even pistons but was freshened up. The crank was 20/20 and it had center billet mains and used Champion irons with a stock unported intake and a 206/206 flat tappet cam and a TE-45a turbo which is a 66mm with a P trim wheel.

60's were NOT maxed out.. Really forget where it was .. We DRIVE out cars a LOT.. We won't run around with pump gas an get our ass kicked by "Scooter" and his ricer that would kill the average Buick. We allways have pushed our Buicks since 1986 !!!!

With 12gph methanol and 288lbs/hr 93 octane you can go 128mph with a 3500lb car. Theoretically 50lb/hr injectors would have that covered. With 25-30gph methanol and 60's which flow more than 60lbs/hr@43psi you could go considerably faster. With 16v and a higher baseline pressure it appears you could make enough power to run 9.60@3500lbs with 60's. I wouldn't try it on a single intank pump though. Voltage covers a lot of sins.

 

[SpeeednV6]

Yea, I was just wondering because this is a brand new turbo. The 60's are new and I thought that because 80's were out, might be the time to get those? I am sure that I am going to get some type of double pumper. Anyone use a Mustang Cobra double set-up?

 

[jasjamz]

No need for the Cobra setup, look at Racetronix for the pieces to build a double pumper.

I agree MID 10's w/one pump w/60's and alky is cool. He'll have a cushion since it's been PROVED that it can go into the 9's.
