10 second motors are not cheap to build correctly. It can be done but it will not last. Don't try to build one on a budget, you will be sorry.

[T What?]

I heard it's cheaper to build a 9 sec motor

 

[coach]

stock 109 w/ good machine work
ported irons heads and stock intake
stock crank
billet mains
roller cam
62mm or bigger turbo
TT chip and either race gas or ALKY.
good intercooler
good tranny

pretty much sums it up. A nice set of trailing arms and airbags.

My buddy just went low 11 and has a HORRIBLE 60' time. Will be 10's as soon as we get that fixed.

:biggrin:

Technically you are correct...after you break your first 10 second motor and build it again, you will only want to build a 9 second motor once, the right way.

what are some 9/10 second engine build up combinations built the right way that the stock 109 with a good engine builder would be lacking? i ask because im building a motor in the fall and want to get it right. thanks

I recently installed a Weber built longblock a few months back. So far I'm very pleased with the engine. We logged a 300 miles on it last Saturday in the 98 degree heat.

Grumpy,

If you don't mind how much boost and timing was on that run? What CR does it have? :redface: IF I ever lean on my combo HARD, that is what I would like to run.

 

[blackgn1]

Yes Grumpy how much boost? I know it wasn't 24psi. Haha. Its been a few years now!! Come off with a little secret info!!!

 

[87WE4BOOSTED]

Combo

I should have known better. That is like asking the Colonel for the 12 secret herbs and spices. I will figure it out with time.

 

[bad V6]

87WE4BOOSTED, what turbo are you running with that Weber built motor? And how do you like it? I'm trying to decide which turbo to step up to in the future.

 

[williambavila]

i have purchased one from thessman it seems to be great and very strong running have about 100 miles on it and am very happy.

hahahaha.. nah I don't live on the Buick sites like I use to .. relaxing on a boat with the dogs.. Oh the dogs like cars to but right now in the hot season they want to chill in the water Really forget what she had for timing.. come on !! That was 3 years ago !! Boost was TSM boost :biggrin:...
Combo's are all different so performance will vary . as far as tuning TT chips only have so many settings. This is not Rocket Science .. TRY different settings !! Of course EVERYTHING else better be up to taking a beating .. Oh NO KNOCK

Hey BadV6,

I have not recieved my motor yet. Bill (WRE) told me it should be leaving their building sometime this week. :biggrin: As far as the Turbo, I have not picked it up yet but I will be running the Billet 6765 JB. I think any thing 66mm & up should do us justice.

Hey Grumpy, I'm glad you caught the humor in that. I will be using a TT chip as well, so I'm sure I will find that sweet spot. It may take me a few seasons but I'm sure I will find it.

You have some beautiful dogs as well..
