I concur, most of the shops I deal with are seeing about ~10RWHP gains with the TFS heads over well done PI heads on a combo like this. Logan Motorsports was the first to test 3 sets of TFS and find 8RWHP the biggest difference against his custom Livernois PI heads (and got roasted online for saying it). Change the graph in the opening picture to SAE and its ~330RWHP which is pretty close to a 233 duration cammed, TFS intaked, ported PI head motor in output. Some numbers I am seeing thrown around here make it sound like the TFS is making more power than a 4V head which I can assure you it is not.
Superchargers Vs. N/A
Blondes Vs. Brunetts
Both will give you a heck of a ride but once you've been with a Blonde for a while you begin to appriciate the brunett even more.
Are you people missing the fact that yeah if the stock TF heads only gets 8-10 more horses against a well ported stage III PI head imagine the numbers of a well ported TF head?
+ ∞.
375 rwhp from nothing but heads and cams? Pa-leeze. That's more than a stock Terminator makes. And it's got 4 valve heads and a blower. Maybe a car did make 375 (or 350, or whatever) on a particular day on a particular dyno with a particular correction factor, but I bet it won't run much (if any) faster at the track than a ported PI/cammed/full bolt on 2 valve (making 325) does.
the tfs heads outflow 4v heads rite out of the box
Yea, but they dont touch a ported 4v head.

oh most definitly i concur there, but still on the same note when the tf heads are ported theyre still up there with the ported 4v heads.
and to hotstang you posted a link to a b.s. electric s/c, come on man even the dumbest town idiot would buy that crap. trick flow has been around for years not to mention theyve one of the r&d departmants in the business. even corrected hp over standerd only shows a +/- 10-15hp difference.

I'm just proving a point...... that 380 claimed by t/f isthe manuf claims are all bs.
Sorry but you are wrong in this case. That 380HP we claim in proven in our own shop car from an outside dyno shop.
Sorry but you are wrong in this case. That 380HP we claim in proven in our own shop car from an outside dyno shop. Also keep in mind that this is 380 at the crank. Our car made 333 RWHP.

I wasn't born yesterday Gregg@TFS.... Maybe some people will buy your claim of 333rwhp by bolting that kit on with no supporting mods but not I.
Let's say for the sake of it though you were correct.....
The original poster had 340hp. and that number was blown up by not being sae. So let's say he's 330hp.
Let's see, he has your kit +
Headers
x pipe
SLP catback
Pulley's
Intake manifold.
He must have one weak car if it should be making 330 with just the head kit you guys have. I mean he must be down what, 30-40 hp?
He either has a very weak car, or your numbers are not correct.....being that I believe he has a very strong car then it's probably the latter.
PS, what would you expect steeda to say about 8hp on their UDP's? I'm sure they have "proof". How about JLT 8hp CAI? I'm sure they have proof. 8-12hp Accufab TB/Plenum combo? They have "proof" too. Will anyone ever see those numbers in the real world? I think not.
There is no way that you are outproducing a standard supercharger system like the vortech on a bone stock GT and if that's your claim put your money where your mouth is. You have claimed a 16hp advantage over a standard vortech kit per your claim. I have some deep pockets and would love for you to prove me wrong. We'll get a bone stock GT. and use a shop we can both be agreeable on. You bolt on yours, I'll bolt on Vortech. We'll put some nice coin on it ..... and, loser pays all parts/ service work. Send me a pm and I'll give you my contact info. You know darn well I'd be walking away with your $$ This is ridiculous, balls in your court greg@tfs.......
man o man, are you conceated, or just and igmo. dude you got 98cobra281 makin more then 300+hp out of a built, p&p npi headed car, youve got jim from cms raving over his cams in the tfs heads making more then 330hp, then youve got a guy from tfs itself confirming the claim, and for god sake man read the original posters thread start up, the dyno slip in the top right hand corner shows clear as day bright as a shiny star, (STD) were im from that means standard. the correct term your looking for is corrected, hell depending on were hes at the corrected hp rating could net him +/- 15-20hp. so what did we learn class, looks like hotstang is jealous cause he spent money on a f/i kit and now theres a head combo thats gonna eat his lil car up.but hey theres always somebody thats gonna be skeptical, hell i bet you still beleive in santa
