Forced Induction

Ok Guys how much boost is safe to run on the The stock bottom end without upgrading it. I aslo don't want to spend money on the tranny either. Do you think this is doable without blowing anything.

 

[Marc T]

There will always be concern, but 5-6 lbs should be oK as long as you are not racing her on a regular basis, but obviously there are never any guarantees!!!

ROE swears that the SC they offer is safe on a stock engine and tranny.

PROF has it on his RC with stock inernals. He swears by it. Give me couple months, and so will I.

Give me a few more months and I will report also!!! :rock:

roe 5-6
Paxton 7-8....I (and a few others) ran 9

I would say 9 would be close to the max on stock internals w/ a paxton.

I think Patrick is correct...the higher you go the closer you get to trouble.

"Trouble"...................a utilitarian euphemism for "kablooey"............

I run 22 to 26 without problems.

O shit , you talking about the FI , not the tyres...

Now serious Annu, If i'm correct :dontknow: you gain about 150 hp with the max boost within safe limits... I think boosted engines must be designed for that , they have a lower compression for a start. Knock will always destroy your engine as fuel-octane and compression ratio don't match...

Isn't there another way to reach those extra horses on a much safer basis and perhaps cheaper :dontknow: :dontknow:

The only cheaper way is by using NOS.

From the prices I have seen here for what people pay for heads, rockers, pushrods, etc., a rebuild to get you to the same NA HP would be 2 to 3 times the cost of the Roe or Paxton route.

 

[ViperTruck2933]

I think pretty much ALL of the QC guys who put on a S/C had to upgrade the tranny. Their may be a couple who didn't. They'll chime in I'm sure.

Hmm..I know ViperTruck is doing a NA build and I thought it was cheaper than the S/C route..maybe he will jump in here..Oh wait..I think he is having his heads ported..not buying new ones..So you are probably correct Silver. From what I recall seeing, the cost of the new heads is equal to the S/C cost..course Im too lazy to look it up,...lol

Even those who did had some tranny issues! lol

Any FI and your stock tranny is gone....but you don't have to go crazy on a trans build....$1000.00 worth of upgraded parts and labor will allow you to run a safe 600+ rwhp FI package...

N/A build with strikers = $13000ish for 550-570rwhp

And as Nowwhat said before, it'll prolly run around 6K to be in the 540 to 550 rwhp area with mildly ported stock heads, bigger cam, roller rockers (what I am doing).

30ish rwhp for the Strikers over the ported OE's doesn't soud so good...

Hey Marc T-

Is that intake manifold and, er, "throttle body holder", powder coated black?

It sure looks sharp.

I think everything Marc has is black...I'm afraid to check, but I'll bet that at least one of his boards is high gloss black! (Probably a long board, which by the way RULE!)

 

[BlackKnight]

For the QCs, would there be any issue with the stock rear end when running FI? I know the tranny won't last but does the rear end also need to be stronger than stock?

The stock rearend is a Dana 60, they can take a licking.
