DD AMS 42R? Is anyone doing this? ANY 42R.
The ETS/ER Drag 1G has a 4202 on a 10:1 2.0l on E85. IT made 680whp at low boost, and made 820@37psi. The one thing that really impressed me (I will look for the dynosheet shortly) is that it was making 400+whp at 6k.
I think its more about how you manage the build and what goals you build for. I think Aaron's car is going to be a really good test, that will replicated at least 2 or 3 more times in the future

I like that debate that is going I just think a couple of you are off base in what this discussion is really looking towards, your combo. Mine will be done next March, at that time if you want to chime in what you don't like, do it then. It's pointless right now as all the motor is, Thoery from experience of a few very well versed tuners that I trust.
I'd like people to return to what your experience was with your build was. My motor is already preatty much on paper and awaiting alittle work, and alot of money.
Here is the dynosheet but the RPM wasnt enabled for some reason just mph. I will look up the gearing for a 1G and then calculate approx rpm values at speed with the 26" slicks.

So the 3rd gear in a DSM is 1.217, FD is 4.153 so the effective ratio is 5.05 (about like a IX in 4th). With a 26" tire this means every 40mph is 2612rpm. Enjoy

For the record it means that Jeff's 42R car was making 400+whp as low as 5230rpm. This isnt a typical build or fuel, but it shows whats possible when everything comes together. This car when it made the 680whp made it at 24.5psi as well.
Disregard the RPM per mph for now...somethings not quite right.

i disagree about doing a 2.3 with the 42r... it will help it spool up a little bit quicker, but a turbo that large needs at least a 9000-9500 rpm redline to fully use the power band it wants to deliver.
Keep it a 2.0 or if you want to get crazy do a 2.1 de-stroker. You will need a really good combination of bottom end components, Ditch the balance shafts (i would recommend AMS race BS, great quality regardless of price, and i had no BS installing mine), good bearings (im sure english racing wont have any problems building a motor for this setup). Have the head ported by somebody that knows what they are doing, high quality valvetrain is a MUST to survive really high rpm, 1mm oversized valves to match the porting. I would probably go with a bigger cam though... the kelford 272 is a nice cam (i have them as well), but i think something with a tad more lift and more "real" duration. Like the FP5r or tomei 280, GSC s3's ect...
keep us updated!!!

I disagree with your setup almost down to every last detail. If hes wanting a 42r for the street but is afraid the lag will be too much. Then going with the biggest of the biggest isnt the way to go about it. Take myself. Smaller 42 (non BB) with a smaller a/r.....1.15. Take my cams for instance....stock, yes, stock. But only for a short while, as Comp 101200s are what im wanting (but i have been looking at the fp4r cams). The reason for the 272 style cam is simply for one reason. I dont want to loose all my mid range. Trust me, the turbo will take care of the 8k + rpm part. You dont need cams for that. Not for the street anyway. Jake Montgomery ran 9.13 @ 160 i believe on the 101200s, WITH A STOCK UNPORTED 1g Head. They do the trick.
Also, **** the port work, you dont need that **** either. Your head is fine the way it is, if anything, touch everything up, smooth the runners out (if u look, they are rough, well, my 13 year old design is). There should be a lip inside your intake runners on the head, take that out to free up a little more room (i dont have that done to mine, mine is an untouched, "2g" head). If he wants to go oversided valves, fine. But like i said, Jake Montgomery was on an untouched head, but if you feel that you need to do this and that to the head for power, go for it. Its your money, not mine.
Buying the destroker would be something i agree with. They are ****ing awesome, simple as that. I run just a 2 liter with Manley and ARP everything. ACL Bearings. Pretty simple really, no BS either.
SMIM is a must, as your doing nothing for that turbo (up top) without one. I run a stock one btw. Keep the stock TB if u like. Hell, i would. Well a 1g for me (60mm). Not sure what size yours is.
Just my opinion. Nothing wrong with a gigantic turbo for the top end and smaller **** for the mid range. A lot of people do the EXACT opposite. Smaller turbo for mid range, big **** for top end.

if you would have read his post, the OP never said ANYTHING regarding turbo lag. everybody else did.... your setup will NOT make 800-1000 AWHP, thats the type of power he's looking for.
I have seen what type of boost levels it takes on a evo just to crack 800whp on a small 42r with small cams (HKS 272), 9.5:1 motor, and no porting, 60~psi and it eventually blew the head apart.
Im not saying the stock head isnt good... but its not good to make 800+hp with ease, neither are any of the cams you are talking about. And Dave Buschur went 9.1 at 15x mph on a f'in 35r, so im not impressed with Jake Montgomery doing the same with 42r. If his head is still stock with tiny cams for his 8.66 run, thats more impressive, but i bet his car is laggy regardless of what cams are in it with the 4202...
And comparing timeslips vs. setups is retarded, unless its the same car and same driver... more importantly the driver...
And i dont mean to bash your setup or ideas, just you were talking about running 9's and such, it seems he is looking for power first.

Really looking to do something sort of unique, build a bunch of power and have something where people just are in awe of a 400-500hp per liter car. I'm from Montana where there is very very few truely fast well built imports. I live in Wyoming right now and it's even worse here. I like going to the car shows and drag race events up here and having these V-8 guys appeciate my car. And then beat them.....Bad. My father is a drag racer and he races a 9.8ET 68 GTO backet car. I really want to beat him, then put the spare tire in the trunk and drive back to the house before he gets his car on the trailer.
I was looking at the speed during the pull and I realised that the gearing I listed is incorrect. Jeff's car is more like 3k per 40mph so its back like I had said before...400whp by 6000.

Are u ****ing ****ting me? I just got done doing a 3rd gear pull today getting the boost ramped up at 3:16 AM. The car has run for a while now. Ever heard of break in period? Why arent you gonna be at the Rock in Nov? Because your **** dont run worth a ****. Zack, your a ****ing idiot. Your car is useless. Ive heard from NUMEROUS people that your car felt stronger on the stock motor then it does on the built 2.3. So dont even think for one second you know how to build a ****ing thing. You dont even do your own work for the most part. From what im told. Chris does it for you.

Big **** will only make lag even greater. Big IC piping, big head, big cams.....get it? My setup was all aftermarket, just smaller things then 5r's or Tomei 280s. You can make power with this turbo without having huge everything. And not on 60psi. Ive seen over 700whp on Comp101200s, stock 1g head, stock valve springs, 1g TB (small 60mm), DSMlink, yada yada. And im not talking about 1 car in particular, ive seen a couple. 1 of which made over 700whp only pulling to 7800 because the PTE1000s were maxed @ 34psi. Each car was on 34psi. Only 1 of which is on e85.
The way he talks, overall HP isnt something hes gunning for. Not to mention, my way would be quite a bit more streetable then your method. Or the biggest of everything theory.
