I don't remember exactly, but I know I found 2 on this board that were making 500rwhp with LT1 castings. I'm guessing they spent a lot of time and money to do it. Don't get me wrong.

 

Well get it done already, slacker Just kiddin'...I can't wait to see the results.

 

If you want 500rwhp call Ai. I remember phil saying he was working on some packages to make 500rwhp on stock castings. That was a couple of years ago.

 

There have been a few to claim that on this site...still waiting to see a post on it being achieved.

 

A porter down here is claiming 300+ out of stock castings but they have to be welded on and 2.0 intake valves. That's 620+FWHP and with auto that's roughly 508RWHP so don't say it can't be done. One guy running his heads with a 383 went 10.3's in a 3400lb car so that would seem to prove the HP. 10.3's is low but it was on some of his first passes and needs more tweeking.

 

Not everyone one running someone's heads are on the net or post up results.

This is a tough crowd and can see why some just dont post. There is someone always qualifying why the results posted are BS or it dont meet some pre-formed notion, etc.

And what does the RWHP mean in the real world? That it can produce that much power, but what is that person doing with that power? Been to many a track with some 'high' HP cars that get waxed by the stock motor'd car. There is way more to a combo than just the dyno numbers and really those numbers done mean much if anything, what matters is does the car perform to what the end user was looking for.

The LE/Ai debate will probably never end but do enjoy seeing the track numbers and more importantly the MPH that is posted from these set ups.

 

Since you have been around this site long enough would expect you to know ful well that a company like AI would certainly create a post if they had a customer achieve 500rwp on stock castings. Any vendo would post this stuff, even ifthere customer wasnt a online type of person. Its good advertising. MPH doesnt mean s much anymore as people use think. What are you making powerwise....300rwhp??? You trap 113 which is what most mild heads/cam seups run with 60rwhp more than you. Suspension, gear and weight reduction like you have done makes a big difference.

 

Word of advice...just make a stout combo and put the boost to it and make an easy 500 rwhp...and be done with it with room to grow. You can buy an s-trim setup used for cheap.

500 rwhp NA is a tall order and when your M6 explodes and you decide to go the TH-400 route that number gets really hard to get.

 

Ai probably is spending time on R&D rather than posting up customer's power numbers. To me it is not Ai's place to post numbers from a customer without prior approval. I run a small shop and not everyone wants their combo released for different reasons, we all know that. I am an open book about my car, it's mine and is built to promote my small business. And when they have posted results there is always posts made "oh that's a race car" or that's not a street car, or some other BS.

And MPH dont mean so much!??! Suspension is key to getting the power to the ground and not waisting any of it. Choosing the proper gearing is key, this includes the 1st gear ratio and final gears plus the tire size is part of that equation. Weight reduction helps alot and running in good air but MPH is the key to it all, that shows the HP you are making. And my car tyipically runs in the 113s and has been in the 115 range, I am making little power but using all of it. I do not know how much power the car was making, it never was on the dyno and it needed to be, I bet there was a few more ponies to be extracted.

And all the racers that are out there TnTing to find that last bit of power, they dont look at the ET, they look at the MPH, did that change help them make power, if the MPH goes up then yes, if it didnt then that change didnt help. Then you start looking at ET and in our case we look at the 60' and then the 330' marks, after that the other lane is catching up.

Good luck to all of those working on new combos and trying to get the most out of them, it is not going to happen on the first pass.

 

Ain't that the truth my friend.

Tweaking my setup took me from 12.8's @ 105 to 12.0's @ 112 with no increase in power, just change in weather conditions and other small details Took me over a year to get there though.

That being said, I hope to be Lloyd/Bret's ET/mph posterchild on the board once I get my 355 up and running. Unfortunately, my old shortblock gave up the ghost before I could get decent times out of it. Full weight Z28, no plans on hardcore weight reduction.

 

And speaking of marketing, what can one say about the TA on Ai's site:
"Our new Fully CNC Ported LT1 Packages (190cc's) are finding great success at the track! Thus far Rick Abare's 94 TA has run 10.20@134.8mph in 2000ft Density Altitude! This is a 3420lb car with our STREET package." And did you know, that was with an A4 (4l60E)

 

As long as the customer wasnt being identified I can see companies saying they achieved "xxx" in house with stock castings and post a graph.

As far as mph, of course it is indicative of hp, but more so of the total combo (that was my point). People think 300rwhp fbodies trap 106-107mph...well that is what 99% of the street cars you see (normal weight and stock suspension)...but that is not what 300rwhp is capable of. 300rwp is capble of mph like your car (maybe more like 111mph), but the mph can drastically change with weight, suspension and gearing. Therefor mph doesnt mean as much aymore when people talk hp because the combos are getting better and better and more people like yourself are squeaking every mph/ET out of your combo thru chassis tuning and gearing.

If you didnt list your mods, and just said you run high 11's @ 113mph, 99.9% of the peole on the site would asume you have an auto with a cam or mild heads/cam and make 350rwhp... so your trap isnt necessarly indicative of what most people think the corresponding power is.

 

its hard to do. my cousin has a fully ported LT4, 383.....and just got 500hp. he dropped some money in the bottom end though!

 

HP at the wheels or at the flywheel??

 

wheels! the custom cam gave him like a 45hp increase. its wicked fast!
