My delta 264/272 camshafts Open down pipe 700-850 rpm. Automatic tranny.
YouTube - Eagle talon with 264/272 Delta cams

Hahah this reminds me of my old GSX. The sound of the open downpipe was rediculous, sounded like a dump truck. My favorite part was the turbo whistle. Sounds good.

Any chance you can help identify the cams I have? They have the 'J' stamped at one end, like deltas, and they also have a '24' stamped into them. Do your deltas have a 24 stamped in them?

The cams was my originals i pulled out of my car i then sent them to delta and they ground them to different specs. My cams does have a j stamped on them. When delta regrinds cams they paint them blue in a couple spots to show that they have a race spec. They also engrave on the end of the cam what they are like 264 or 272.

Here some pictures of the cams after they came back.

If i woulda known these were under $200 i woulda forwent my light flywheel and popped these in when my timing belt was off. Now the motors in the car, i cant imagine re-timing it without a tensioner tool jobby. Ill get the 280's in June then, when i put some valves/springs/etc. in.

With a M8 x 1.25 threaded rod and two hex nuts double nutted on one end I can compress the auto tensioner, and swap cams out in about an hour.
No need to re-time either...

I'm going to get some of these for my 1G AWD with a Holset turbo; since it's an automatic I want as fast of spool as possible. Did these make your spoolup slower, faster, or unchanged?

I found a long bolt (that wasn't quite long enough) and welded another bolt to it and ground it smooth again. It works great. I had a threaded rod, but regular threaded rod is too soft and it bent every time I used it.

Yep, you are right.
Threaded rod is too soft.
I actually have the tool that is made specific for the auto tensioner.
I had to thread my battery stay bolt to replace my buddies cam angle sensor on his 95.
Hardest part was finding a GD M8x1.25mm die....

 

[EclipticalGS]

Thats a good idea, i wasnt aware that worked with 6-bolt block, 7-bolt front case, and a modded 6-bolt timing cover. How does it work?

 

[Delta Cam]

dyno yet? want to see how they do, I'm finishing my personal 4g build. 272 cams, big valves, titanium retainers, dual springs very excited to get it running.

BTW I listen to the video weekly, keeps my moving forward on mine !

Thought I would post this video since the only clips on here with Delta cams that I'm aware of are RedTurboEclipse's (which I think is heavily modded), and Chanley Talon (open dump exhaust).

Here's my car at idle with the Delta 272/272's. The video is dark, but should give you an idea of what these cams sound like on a stock engine with full exhaust.

These were dropped in without degreeing.

[ZenkaiRacerDsM]

Is that the stock exhaust?

 

[kiddsm95]

No, it's a 3" catless TBE. What I meant to convey was that the engine internals are that of a stock 7-bolt. Other mods are in my profile.

Here are some pics of my delta regrinds after 800miles on my new rebuild.

 

[Delta Cam]

look new still

 

[GSXeclipsePSI]

Yes I was very happy when I pulled the valve cover, that and my arps where really tight and only 2 needed to be tighter, I just did 90ft lb on all of them for the hell of it.

 

[dsm-onster]

Well I'd expect cams that are identical material to stock since they are ground of of stock cams to have a great long service life . Regrinds are oem quality with aftermarket performance and all for less !!!!

 

[GSXeclipsePSI]

The more miles I put on I'll keep a photo update, my next one will be at 2k or more.

 

[Slippi84]

Which delta grinds did you go with they have B272s K272s H272s? They mimic other brand cams grinds and the first letter dictates which one.

 

[GSXeclipsePSI]

I did the H272 this was about Sept. 09 I purchased them I didn't know then they had the K272 I might have gone with those. I did notice way more top end with these cams as soon as I switched from the the 16g to the 6152 and I love them soo far.

 

[e85_4g63]

I was under the impression that there H and B where regrinds, and the K272's where ground from new billets? True? for the record, I own there H272's now. No complaints really, they just aren't aggressive enough. I keep my mods to myself but, in case anyone wants to know some basics (16g, e85, 25+ psi, Link v3, 950's, etc). Also an hx35 is on stand by.
