Ok guys can this be done? I called AA yesterday to see if it can, I bet it can be done. A lot of you already know my set up but in case you don’t, AA Twin Screw Stage II, 418HP at the crank.

I spoke to some other guys on this forum and they think yes it can be done,
What I want to achive is 500HP at the crank, on 91 Octane fuel for a street car that will pass smog test.

Cant cut the cats, no race fuel and no NOS.

Maybe Cams?
AA Stage 3?
Different Tuning?

I want bragging rights, I was just at the BMW dealership and they told me there gonna be rolling the 1 series next year and they are already making the 335’s with the twin Turbo, but I love the look of a turbo guy when they cant pass me. Plus Stupid Ford and Chevy already have there 500 HP cars which seem to be the NEW thing.. :shifty

Any ideas??

this would be my next year project if i can afford it

Talk to ///M3///M5 I think his Twin screw hits 500...Maybe its 400, im not sure.

theres no way without going with a pretty big blower, at least a t-trim and some good tuning and a built motor, but everything is possible

Talk to ///M3///M5 I think his Twin screw hits 500...Maybe its 400, im not sure.

400+rwhp

yea i sent him a PM yesterday.. we well see what he says.. i think he hits 400 RWHP but im not sure either

isnt 500 crank about 425 rwhp ?

Yes:)

Ford inflates there hp figures.The new mustang engine is a heap of shit!(2valve)4.6 boat anchor.the gm lsxx engines are under rated or right on.Don't look at hp and say I want such and such amount of crank hp.On who's dyno?Ford's?

That was funny!

I saw a Centri non T Trim S52 in an E30 that runs 10's.

It was at the track and he said he has trapped 130+......... No Spray!

I was just stating that all dyno's are calibrated alittle diff.
I think I know of that e30,does he live near rockford?

to hit 500bHP may be possible,
BUT
bragging rights is a silly reason to do this.

Enjoy your new-found power.

Huh, I live in the detroit area and I know a few guys that have such cars as a GT and a Z06. Ford claims 550hp and it puts somthing like 530 at the tires, sounds like a deflated number. The Z06 claims 505 and puts down 450 at the tires. The 03-04 cobra claims 390 lays down 340's and ls1 commonly put down 280 in stock trim. Hows that inflating.

Thats from motortrend, But what do they know?

because they claim the crank horse power and every car loses power to the wheels. One number is the crank power the other is wheel hp noob

No way! for real.. Just cause I only havea few posts, doesnt make me a noob to cars. He said they claim higher numbers. They just simply claim crank hp, And sometimes its actuall less power at the crank then the cars actuall makes. You could get into the fact if his car makes 416 to the tires now, The engine actually makes more since it takes power to drive the blower.

I believe 410 whp was Thomas's best TS number, which is awfully close to 500bhp. More importantly, he achieved with ~10 psi boost, with a semi conservative (read safe) tune (WOT AFR's in the upper 12's).

I think it could be pushed a bit further (say go with 73-74mm pelley, vs the 76mm with Thomas's set-up), but that would require a retune and would probably whittle away at the safety margins caused by operating the TS blower at those higher rpm's and running higher net compression on a non-built engine running pump gas..... and to what end, for another 15whp?

I say leave good enough alone! This is coming from another Thomas-modified TS (exact set-up as his, making similar power) driver. 410whp is PLENTY fast enough, for cryin' out loud

well its not just bragging rights.. its also more fun to drive!! plus im addected to speed and have always wanted a 500 HP car :devillook

fine.. well i still want to know if it can be done.. but yes its fast already :buttrock

400hp or 500hp ither still = a serious car, and a fun car. Its kinda related, But when I built my mustang, going to the next level cost some serious coin and it lost drivablity.

fine.. well i still want to know if it can be done.. but yes its fast already :buttrock

OF COURSE it can be done, since several TS-equipped cars are maybe 15-20whp from that goal you set of 500bhp. It would involve cams, a re-tune, possibly larger injectors, higher boost and some drop in compression (exact amount of these two TBD). Feel free to lead that charge.....report back

im feeling like im going to lead that charge :alright

i got an pm back from Techno and he said he can make 400 to the wheels. im waiting to hear back on the cost and eveything involved but this is something i would like to research more and if it sounds good pull the triger sometime next year again asuming it will work and i wont be killing the engine life a huge amount.. a little is fine but alot is not :nono

im sure alot of people would be intrested if it all works out.

If you were interested in peak horsepower, why did you get a twinscrew? Not criticizing, just wondering.

Then you shouldn't have bought a TS.

We all told the guy to go turbo, he didnt listen. How long did it take before he needed 'mo powa', a week? :stickoutt

Yep, 7 days. He posted his first impressions on the 11th, and posted this on the 18th. And there was a day in there that he didn't get to drive it because it had to go back to the shop.

OMG Guys! IM soo Happy i did NOT get the Turbo!! I would much rather have the SC, and the Twin Scew to Boot, Each day that goes buy im more glad i did not get the Trubo..

Turbo are not my thing, and i was not orignialy going for MaX BHP anyway i was wanting to know if i could do 500 with my TS. as is the car is plenty fast enough and when i go with stage 3 at 450 BHP that will be insane

i already CANT floor it in 1st for more then maybe 2 Sec's and i have a Vert im not going to be going 150+ on the Highway or Track the car.. again cause its a vert..

and i got the TS a Month after i started that thread FYI

it shouldn't take 90hp to put it to the ground...that sounds like a lot to me

Not sure I follow, but perhaps there's confusion here. The OP wanted 500 CRANK HP on his TS, while there's a fairly well worked out existing solution for 410 WHEEL (Thomas's and now my car), so when you make allowances for drive train losses, the HP needed to reach the OP's 500 bhp goal is around 15 hp. Hope that helps.

FWIW, after expirementing with a "stage II" set-up (lowering compression and upping boost), I decided to go back to the stage I setting -- after my .140 cometic heagasket let go at MidOhio. Mind you, I didn't have a re-tune and that may have contributed to the problem.

In any case, I decided I'd rather trade-off a bit of hp/torque for greater safety margins and longevity, and my car was already plenty fast on the track.

Of course, YMMV*
