Isn't that everyones goal

For that trap speed, and depending on the cars weight, you are going to need/want a turbo that can do ~60lb/min worth of airflow.

So that means a GT35r, GTX3076r, Holset HX35 7-blade, HX40 6/7-blade, LR S65... And of course, it also means a decent amount of boost and good fuel.

I do think you are probably at, or near the limit of the K27/8... I have the same turbo, but not for long

The k27 is a dinosaur haha. I would like my next turbocharger to be a HX35, I would like to run e85, and I would like to run 20-25lbs of boost on a few trophy runs. Would you rather tune a car on E85, 104 or 110 race? What would be the safest fuel to use?

Rogue_Ant

If you go with the HX35, you want the last version, the 7-blade compressor wheel one. That turbo is supposed to flow ~60lb/min. For fuel, I would choose E85; though that means even bigger injectors as E85 requires ~30% more fuel than gasoline.

it depends on what you want to use

i have mine tuned on pump 98ron and e85 on the 2nd map

Was that offered in a late diesel truck? I have been eyeballing your tuning kits for a very long time. Would 83# injectors be appropriate for the application?

Do you have Rogues set up? You can have multiple maps?

Darwantae951

In all honesty, I figured the TT Camaro would have pulled harder.

Paulyy

mine's on order, should be here in a week or so. But yes you can have multiple maps and you change it by a flick of a switch or unplug the coded plug at the DME.

when you order josh asks you a few questions about your engine mods and you tell him the turbo, what injectors or his, FPR, and what maps do you want with your tune.

You'll max the injectors. Also I think an hx40 is the better choice for you considering the displacement. Pair that witha t3 .82 garrett hotside and that woudl be a great combo.

I guess I better get that clutch in quick. You're about to take the #1

Personally I think it should require a second run to set your time. Kind of like the salt flats and other drag records. I never got my second run right on my red car so I couldn't consider it to be valid for my record. I currently have my slower back to back run up on dragtimes for that reason. I'm hoping to at least repeat my 1.6 sixty foot this wednesday. That will have to be my record for now.

You obviously know how to drive these cars. Glad to see there is some interest in setting a new record.

Rogue_Ant

Yep, the 80# injectors will max out around 450rwhp on E85... I am looking into a 100lb/min+ injector for those who really want to push the envelope...

Sid is right, the HX40 would be less stressed than the HX35 doing ~500rwhp.
The best HX35 came from 98.5 to early 04 Dodge Cummins pickups.

That Camaro is a very fast car but my 2.8L is a peppy little machine. I am convinced that this 2.8L will allow me to keep up with a few more bolt on's.

Now that is AWESOME! All in a nut shell, I could run E85 daily and I could run 110 race gas at the track with the flip of a switch?

Where would I find such a turbo do you have any vendors in mind? I will finish the year with the K27 so I really doubt I will go much lower than a 12.4. I had a few 12.4-12.5 runs. Traction has been a big issue, my best 60' time was 2.0s. Your short time is crazy! How did you manage a 1.6!? It took me a long time to figure out how to launch a 944.

Hurry along and get that clutch installed so we can have a friendly rivalry I will be sure to do a few runs with my 2.5L as well. I would really like to get to the 12s with that too.

piperporsche180944

Would the HX40 have a peaky powerband? I would like something that offers a broad powerband. I am willing to be a pioneer with this, I would love to make 500+rwhp.

I currently have a 40super/35 hybrid on it. I haven't ran it yet with this turbo. I was out of turbo up here with the hx35 8 blade. The hybrid spools 15 psi at 3400rpm in 4th using a t4 .48 HS (similiar to the .82 t3). I really like it. It will destroy the tires in first and second with little effort. So far I have measured about 70 hp more worth of air with it. Unfortunately I can only use it on a roll on and I have to keep the boost down due to the injectors maxxing out.

I should probably not give away my launch technique quite yet . I will say that It came out on minimal boost and actually used first gear compared to my tire shredding previous runs. This was on Kuhmo radials too. I'm not sure if I'll be able to back it up but I'm going to try.

I am looking forward to using a full 40 super on my lightweight car in the near future.

If you are looking for a holset hx 40 you will want the 6 or seven blade version. It is very easy to mate a garrett hotside to them.

Darwantae951

I hope so. Your video makes me hopeful of the performance I hope to get out of mine. I'm only running 7lbs and can't wait to turn it up a little bit.

piperporsche180944

I will do a ebay search, hopefully there arent a lot of chinese garbage turbos. I have only ran my 951s with street tires, 255s on my 2.8L and 245s and 225s on the 2.5L. Maybe I should try some slicks out, I do have 2 extra transaxles.

Your launch advice would be appreciated. :P

How did you build a 3.1L? Your car should haul at a higher boost setting!

Darwantae951

Basically an overbored 3L (106mm) with internals to handle the power.
