I have seen a lot of people on ls1tech say "wish I put my car on the dyno when it was stock to get start point"etc so I thought I had better do a dyno run for a start point but 2 nights ago I fitted my new Loud mouth,Slp lid,smooth belows and filter from flo pac that everyone says is crap so not totally stock but (love the loud mouth by the way great sound)with stock tune I got 337.8RWHP is that normal for just these mods I couldnt belive it I was honestly expecting 280hp or something cant wait to do Slp diablo tune,pulley, SSRA,thermostat,3.73s, Bfg drag radials sfcs and lcas most of wich is going on this weekend and next week.Guess I will be into the 12s without headers,ory and stall.

 

great numbers. but some advice would be to get a tune from EFI live or LS1edit if tis possible.

 

Theres something wrong with that car. I'd get rid of it.

 

Why get rid of it? And I will do HP tuners or EFI live etc when I do headers next year.

 

so he can have it. those are some pretty good numbers for a lid and catback.

 

Yes I thought so 2 nights ago I also run 13.58 1/4 with old hard tyres(spinning every where) man fbodys have bad traction with stock suspension.

 

no, just bad tires... get some Nittos and you will hook up

 

great numbers, you put some 555R's on you will be much faster

 

Nittos or BFGs

 

Mickey Thompson Street ET Radial

 

Good numbers but you might end up changing you mind about the sloppy sound of the loudmouth after you get headers. Unless you like rasp. I have heard the LMII is better though. You could always try swappin out bullets also.

 

Or just run a catted Y pipe

 

They dont come in 315s do they?And Orangepeel & Lithium if you read this I guess it must have been the special oil in my air filter

No 315x17 so BFGs or Nittos

 

wow, good numbers, but guessing the dyno is slightly off. Unless you got a wednesday car. How did you have it dynoed? Mustang? dynojet? I would not waste any $$ on the diablo tune.

 

17" no but they are almost a little too wide as you'll have to hack the arches most likely and a little more sidewall is often beneficial.

I'd probably run 275's front and rear but not DR's on the front.

 

I have 315s now and no problem.And daryl2cb I am in Japan so dont know what kind of Dyno but it was a drive on strap the car down wheels on the roller type dyno.But one secret weapon I have is premium grade gasoline here is 100+ octane

 

how did u get your car in japan, i thought they had a law where you couldnt import cars there

 

Was that dyno number SAE corrected? If so then really nice numbers....and if not.......still not bad numbers depending on the correction.


Did you put a LS6 intake on there?

Did you figure anything out with the throttle body we talked about?
