I'm wondering what my mph should be with my 67bb turbo on pump gas, no alky. I was at 111mph with the 44 and since have added a 210/215 roller and a 70mm throttle body.
Going from a stock turbo(106mph) to the 44(111mph) was a gain on pump gas. I thought bigger turbos make more power and less heat at the same boost level. I was running 16lbs of boost on the stock and 44 turbo. Also, I have GN1 heads and ported intake. The stock throttle body was the last restriction I had as everything else (intercooler, dp etc. is at least 3inches).
I replied to your PM about the alky/no alky race fuel/no race fuel. You should be able to tune it to 120 mph on pump gas but you will need to rev it a little. You could remove some weight to make it easier. You really need a better tuning tool than a Scanmaster. An EGT or Wideband with data logging will make tuning much more consistent. I would not wait to install the kit. It will easily allow you to run 25 psi and make a lot more power.Bison,I have a 3200 stall from CK performance and trans so that should help. The 111mph was with no knock from the scanmaster 2.1 with the 44 turbo on 93 octane 16lbs of booost with 19 degree timing on the translater and the champion heads.. When I added the GN1s that was a huge difference even with the stock turbo on pump gas. My new engine is beening put together now. I am adding a 210/215 comp roller cam, 6776bb turbo, 70mm throttle body and plenum, pts radiator, rjc pulleys, girdle, bigger oil pan with crank scraper, power plate, wire and harness from caspers, double pumper, new gas tank and a few other goodies. I have a SMC alky kit if I decide to put it on. I already have Champion GN1 aluminum heads, ported intake, 60 pound injectors and a 3"thdp hooked to a atr exhaust and ported matched stock headers. When you ran the 117 was that with alky? I am hoping to run around 120mph on pump gas/no alky then add the alky later. I want to know what my car will do with the upgrades as I have improved mph with every turbo upgarde on pump gas. Then I will add race gas and get a time, the I might put the alky kit back on. I ran a 12.3 with the stock heads and the 44 with the alky a few years ago.
With my luck something will go wrong sooner or later. The last engine lasted 5,000 miles as it wiped a cam an I had metal everywhere. How much safer would a tune be using 93 octane with the fast system versus the stock ecm and a translater? I'm asking because I may go with it later.
I don't think fast will make it safer. IMO with the upgrades available for the stock ECM like the trans pro the advantage of going to FAST is minimal and really only shows up in the user interface department. So we're clear I've never used FAST but it doesn't look like it can do anything significantly better than the stock ECM with some piggyback options. That's my .02. james
Like I said I haven't used FAST. I think bruce (RIP) had traction control with the stock ECM so it is possible. I think you reaffirmed what I said in that it's just easier to get from point a to point b with an aftermarket ECU. You can still get to point b with the factory stuff though. As for reliability I've seen more posts about 2 month old aftermarket ECU's losing a driver or something and costing an engine than I have about 20 year old ECU's costing an engine so IMO the reliability thing is up in the air. Don't get me wrong, I think the aftermarket ECU's are great, I just think they're a little over hyped and that most people that go to them probably don't need to. Notice I said need. If someone wants to go FAST for the interface then it's there money and if you've got it I say spend it cause' it's no fun if you die with it! But, (and this is really a question because I haven't used FAST) is FAST going to do anything to keep an engine safe that you can't do with a stock ecu and some piggybacks?
You wouldnt understand unless you used one. It will add fuel instantly to prevent a lean out and there are a lot of cells to program. The cells can be shifted sot hat the user has more programability where the engine spends most of its time. If the stock ecm was more reliable then there is no doubt the really fast guys would be all over it. The stock ecm rev limit cant even be raised over 6375 without removing it totally.
